Define a Pet class that stores the pet’s name, age, and weight. Add
appropriate constructors, accessor functions, and mutator
functions.
Below is the C++ code for defining a Pet class that stores the pet’s name, age, and weight. The code also includes appropriate constructors, accessor functions, and mutator functions.
##C++ code for defining Pet class`
`
#include<stdio.h>
using namespace std;
class Pet {private: string name};
int age; double weight;
public: Pet(string n, int a, double w)
{
name = n; age = a; weight = w;
}
void setName(string n) { name = n };
string getName() { return name; }
void setAge(int a) { age = a; }
int getAge() { return age; }
void setWeight(double w) { weight = w; }
double getWeight() {
return weight;
}
void displayInfo() {
cout << "Name: " << name << endl; cout << "Age: " << age << endl; cout << "Weight: " << weight << endl;
}
};
int main() {
Pet myPet("Buddy", 5, 15.5);
myPet.displayInfo();
return 0;
}
`In the code above, we first include the necessary libraries and declare the Pet class with its private variables: name, age, and weight. We then declare a constructor for the Pet class that takes three arguments: the pet's name, age, and weight.
Next, we define the accessor and mutator functions for each of the private variables. These functions allow us to retrieve or modify the private variables of a Pet object.
Lastly, we define a function called displayInfo() that simply outputs the name, age, and weight of a Pet object.
In the main function, we create a Pet object called myPet with the name "Buddy", age 5, and weight 15.5. We then call the displayInfo() function to display the pet's information
Thus, the above code demonstrates how to define a Pet class that stores the pet’s name, age, and weight along with appropriate constructors, accessor functions, and mutator functions.

T/F: In a relational table, each row is unique and uniqueness is guaranteed because the relation has a non-empty primary key value.
True. In a relational table, each row is unique and uniqueness is guaranteed because the relation has a non-empty primary key value.
A primary key is a column in a table that is used to uniquely identify each row of data. It must contain a unique value for each row and cannot have null values. No two rows in a table can have the same primary key value. If a table does not have a primary key, it is referred to as a heap. This means that the table is an unordered collection of rows with no guaranteed uniqueness. However, adding a primary key to a heap can improve performance by enabling the database management system to locate data more quickly.
Explanation: Every record in a relational database has a primary key. The primary key is a single or group of fields that uniquely identifies the record. The database system can only identify unique records by using the primary key. It is a field or combination of fields that have unique values for each record. In a table, a primary key column cannot be empty or null. It must contain unique values for each row. When we create a table in the database, it is necessary to include a primary key column. A table in a relational database is a collection of records. The rows in a table are also called records or tuples. The columns in a table are called fields or attributes.Conclusion:In conclusion, the given statement is true. In a relational table, each row is unique and uniqueness is guaranteed because the relation has a non-empty primary key value.

This function returns whatever number the user entered. 1. This function receives no parameter, but returns the number of fruits 2. A function that calculates the price of the bag of apples 1. This function receives the number of apples in the bag, multiplies by 3 ($3 per apple) and returns the price of the bag of apples 3. A function that calculates the price of the bag of bananas 1. This function receives the number of bananas in the bag, multiplies by 2 ($2 per banana) and returns the price of the bag of bananas 1. This function receives the number of bananas in the bag, multiplies by 2 ($2 per banana) and returns the price of the bag of bananas 4. A function that receives the price of the bag of bananas and the price of the bag of apples and print it all in a friendly manner such as: "Thank you for shopping with us. You bought $? or bananas and $? of apples. Your final bill is $??" (replace ? with whatever the price is) Once you finish writing your functions, you can do the function call • Call the function #1 and get the number of apples in the bag o Receives nothing as parameter Returns the number of fruits in the bag • Call the function #1 again and get the number of bananas in the bag o Receives nothing as parameter o Returns the number of fruits in the bag • Call the function #2 and get the price of the bag of apples o This function receives the number of apples in the bag o This function returns the price of the bag of apples • Call the function #3 and get the price of the bag of bananas o This function receives the number of bananas in the bag o This function returns the price of the bag of bananas . Call the function #4 and print the final bill o This function receives the price of the bag of banana and the price of the bag of apple as parameters • This function returns nothing Note: • Make sure you have 10/10 on pylint. This is 10% of your grade. No partial grade on this • You are free to modify the functions if you want to. But you must write at least 3 functions. If you do this exercise without using functions you will get zero even though your code might calculate the final price correctly. I am more interested on seeing the functions than anything else • You are free to use global variables if you want
The Python program consists of four functions that calculate the final price of an order containing bags of apples and bananas. The first function prompts the user to enter the number of fruits in the bag and returns that number. The second and third functions calculate the price of the bag of apples and bananas, respectively, based on the number of fruits in each bag. The fourth function takes the prices of the apple and banana bags as inputs and prints the final bill, displaying the quantities and total cost of each fruit type
The program begins by asking the user to input the number of apples and bananas in their respective bags. This is achieved using the first function, which returns the number of fruits in each bag. The second function takes the number of apples as an input and calculates the price of the apple bag by multiplying the number of apples by the price per apple ($3). Similarly, the third function calculates the price of the banana bag by multiplying the number of bananas by the price per banana ($2). Both of these functions return the respective prices.
Finally, the fourth function is called, which takes the prices of the apple and banana bags as parameters. It then prints a friendly message, including the quantities and total cost of the apples and bananas, as well as the final bill. The program executes these function calls to obtain the desired output. By structuring the solution using functions, the code becomes modular and easier to understand and maintain.

The given regular expression is ((ab) | (0|1)). To draw the NFA for this regular expression, we can break it down into smaller components and combine them accordingly. The NFA will have states and transitions representing different possible combinations of the subexpressions within the regular expression.
The regular expression ((ab) | (0|1)) can be divided into three main components: (ab), (0|1), and the outer Kleene closure ().
To draw the NFA, we start with an initial state and create transitions for each possible input. For the component (ab), we create two states and an arrow labeled 'a' from the initial state to the first state, followed by an arrow labeled 'b' from the first state to the second state.
For the component (0|1)*, we create a loop within a state, allowing transitions labeled '0' or '1' to loop back to the same state. This represents zero or more occurrences of '0' or '1'.
Finally, for the outer Kleene closure (*), we connect the final state of the previous components back to the initial state, allowing for repetitions of the entire expression.
The resulting NFA will have multiple states and transitions representing different possible combinations of the subexpressions. It will recognize strings that match the given regular expression, which includes sequences like 'ab', '01', '011010', etc.
In conclusion, the NFA for the given regular expression ((ab) | (0|1)) consists of states, transitions, and loops to represent different combinations and repetitions of 'ab' and '0' or '1'. It provides a visual representation of how the regular expression matches various strings in the language.

The most common pipeline configuration for MIPS processors is the five-stage pipeline. Instruction Fetch (IF), Instruction Decode (ID), Execute (EX), Memory (MEM), and Writeback (WB) are the five stages (WB).
Pipelined Datapath for MIPS Processors [Source: Wikipedia]The branches are the most challenging instructions to handle in a pipelined processor. As we all know, branches modify the control flow, and the processor cannot predict the direction of a branch until the branch instruction is executed (i.e., the branch target address is computed). As a result, when a branch instruction is encountered in the instruction stream, all the instructions fetched after it are potentially incorrect, and the pipeline must be flushed, and the correct instructions must be re-fetched.
When a branch is taken, it must be detected in the EX stage, which causes the IF/ID pipeline register to be flushed, and the correct instructions are fetched starting from the target address

Why did UTF-8 replace the ASCII character-encoding standard?
256. Bits use the binary system, which is also known as the base-2 numeral system. So 2^8 allows us 256 values from 0 to 255
UTF-8 can store a character in more than one byte. UTF-8 replaced the ASCII character-encoding standard because it can store a character in more than a single byte. This allowed us to represent a lot more character types, like emoji.
255. There are 256 values in a byte, from the decimal number 0 to 255.
UTF-8 replaced the ASCII character-encoding standard because it can store a character in more than a single byte, allowing for a wider range of character types, including emojis.
UTF-8, which stands for Unicode Transformation Format 8-bit, is a character encoding scheme that can represent characters from the Unicode character set. It is backward-compatible with ASCII, meaning that the first 128 characters of UTF-8 are the same as ASCII, ensuring that ASCII-encoded text can be correctly interpreted by UTF-8.
The ASCII character-encoding standard uses 7 bits to represent characters, allowing for a total of 128 different characters. However, as technology advanced and the need to support a broader range of characters arose, the limitations of ASCII became apparent. With only 128 characters, ASCII was unable to represent characters from other languages or symbols like emojis.
UTF-8 addressed this limitation by introducing a variable-length encoding scheme. It can use one to four bytes to represent a character, depending on the Unicode code point of the character. This flexibility allowed UTF-8 to encompass the entire Unicode character set, which includes over 137,000 characters.
By using multiple bytes, UTF-8 provides a larger number of possible values for character representation. The initial 128 characters are still represented by a single byte, ensuring backward compatibility with ASCII. However, the remaining characters, including a vast array of international characters, symbols, and emojis, can be represented using two, three, or four bytes as needed.
The adoption of UTF-8 as the dominant character encoding standard brought several advantages. It eliminated the need for different encoding schemes for different languages, streamlining internationalization efforts. It also allowed for seamless integration of various scripts and symbols into a single document or communication medium. The widespread use of UTF-8 has enabled better compatibility, interoperability, and globalization in the digital world.

8. Read two names of your friend and order them in alphabetical order using Compare Methods of String Class.
You can achieve this by using the `compareTo()` method of the String class to compare the two names and then arranging them based on the comparison result.
How can you order two names in alphabetical order using the compare methods of the String class in Java?Below is the Java code that reads two names of your friends and orders them in alphabetical order using the compare methods of the String class:
import java.util.Scanner;
public class Name Ordering {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("Enter the first name: ");
String name1 = scanner.nextLine();
System.out.println("Enter the second name: ");
String name2 = scanner.nextLine();
// Ordering the names in alphabetical order
int result = name1.compareTo(name2);
if (result < 0) {
System.out.println("Ordered names: " + name1 + ", " + name2);
} else if (result > 0) {
System.out.println("Ordered names: " + name2 + ", " + name1);
} else {
System.out.println("Both names are the same: " + name1);
The code begins by importing the necessary packages and creating a Scanner object to read user input. Then, the program prompts the user to enter the first and second names of their friends.
The `compareTo()` method of the String class is used to compare the two names. If `result` is less than 0, it means `name1` comes before `name2` alphabetically, so the names are printed in the order entered.
If `result` is greater than 0, it means `name2` comes before `name1` alphabetically, so the names are printed in reverse order. If `result` is 0, it means both names are the same.
The program then outputs the ordered names based on the comparison result.

The given code will result in a compilation error because of incorrect syntax. It seems to contain several mistakes, such as incomplete variable declarations and incorrect usage of the List Iterator class.
The code snippet provided contains several errors that prevent it from compiling and executing correctly. Let's break down the issues:
1. In the line "List 1 = new List Iterator," there are syntax errors. It seems that the intention is to declare a variable named "1" of type List, but the variable name cannot start with a number. It should be changed to a valid variable name.
2. The correct syntax for creating an Array List using the provided array "a" would be: `Array List<Integer> list = new Array List<>(Arrays.asList(a));`
3. The line "li = 1.listIterator();" is also incorrect. It seems to be an attempt to assign a List Iterator object to the variable "li," but it is missing a valid reference to a list object.
Considering the compilation errors in the code, it is not possible to determine the exact output. However, once the code is corrected and runs without errors, it appears to iterate over the list using a ListIterator.

What is the analysis of the CPU usage, memory usage, and swap space based on the provided "top" command display?From the provided "top" command display, the status of CPU usage, memory usage, and swap space can be analyzed as follows:
1. CPU Usage:
Status: UnacceptableThe CPU usage shows 2.3% in user space (us), 1.7% in system space (sy), and 8.8% in nice processes (ni), which indicates that the CPU is being utilized to some extent. However, the significant concern is the high percentage of wait (wa) time, which is 96.0%. This suggests that the CPU is spending most of its time waiting for I/O operations to complete, indicating a potential bottleneck in the system. The high wait time could be due to disk I/O operations or other resource-intensive tasks.
2. Memory Usage:
Status: AcceptableThe memory usage shows a total of 245,440 kilobytes (k) of memory available, with 241,084k used and 4,436k free. Additionally, there are 496k buffers. Although the total memory usage is relatively high, with most of it being utilized, there is still a small amount of free memory available. The buffer size is also relatively small. However, without further context on the system's requirements and workload, it is difficult to determine if the memory usage is a cause for the system running slow.
3. Swap Space:
Status: AcceptableThe swap space shows a total of 409,596 kilobytes (k) available, with 5,436k used and 484,160k free. Additionally, there is 182,812k cached. The swap space is primarily used as a backup when the physical memory (RAM) is fully utilized. In this case, the amount of swap space being used is relatively low, and there is a significant amount of free swap space available. The cached memory suggests that the system is utilizing some memory for caching purposes, which can help improve performance.
Overall, the CPU usage with high wait time indicates a potential bottleneck in the system, while the memory usage and swap space are within acceptable limits. Further analysis of the system's specific requirements, processes, and workload would be necessary to identify the exact cause of the slow performance.

When is it more useful to define a template, rather than
defining a base class? (2 marks)
How is new operator different than malloc? (2 marks)
It is more useful to define a template when you want to create generic code that can work with different data types, whereas defining a base class is useful when you want to create a hierarchy of classes with shared characteristics and behaviors.
Defining a template allows you to write code that can be reused with different data types without duplicating the code. Templates provide a way to create generic algorithms or data structures that can work with various types, promoting code reuse and flexibility.
On the other hand, defining a base class is beneficial when you want to establish a hierarchy of classes, with the base class containing common attributes and behaviors shared by its derived classes. Inheritance allows derived classes to inherit and extend the functionality of the base class, enabling code reuse and promoting modularity.

Haskell code for implementing resolutions.
First, let's define the necessary helper functions. We'll assume that you already have a module named Formula that provides the required data types and functions for working with logical formulas.
haskell
Copy code
import Data.List
import Formula
-- Helper function to check if two formulas are complementary
areComplementary :: Formula -> Formula -> Bool
areComplementary f1 f2 = case (f1, f2) of
(Not p, q) -> p == q
(p, Not q) -> p == q
_ -> False
-- Helper function to eliminate duplicates from a list
removeDuplicates :: Eq a => [a] -> [a]
removeDuplicates = nub
-- Helper function to perform a single resolution step on a pair of formulas
resolve :: Formula -> Formula -> [Formula]
resolve f1 f2 = case (f1, f2) of
(Or l1 r1, Or l2 r2) -> removeDuplicates $ (resolve l1 l2) ++ (resolve l1 r2) ++ (resolve r1 l2) ++ (resolve r1 r2)
(Not p, q) -> if p == q then [TrueFormula] else []
(p, Not q) -> if p == q then [TrueFormula] else []
_ -> []
-- Helper function to perform a full resolution step on a list of formulas
resolveStep :: [Formula] -> [Formula]
resolveStep formulas = removeDuplicates $ concat [resolve f1 f2 | f1 <- formulas, f2 <- formulas, f1 /= f2]
-- Main function to check if a formula is unsatisfiable using resolution
unsatisfiable :: Formula -> Bool
unsatisfiable formula = go [formula]
where
go formulas
| TrueFormula `elem` formulas = True
| null newFormulas = False
| otherwise = go newFormulas
where
newFormulas = resolveStep formulas
Now you can use the unsatisfiable function to check if a formula is unsatisfiable using the resolution method. For example:
haskell
Copy code
main :: IO ()
main = do
let formula = -- Define your formula here
let isUnsatisfiable = unsatisfiable formula
putStrLn $ "Is the formula unsatisfiable? " ++ show isUnsatisfiable
Make sure to replace -- Define your formula here with the actual formula you want to check.
Note that this implementation uses a basic form of resolution where it repeatedly applies resolution steps until either a contradiction (TrueFormula) is reached or no further resolutions are possible. This approach may not be efficient for large formulas, so additional optimizations might be necessary for practical use.

discuss the relative merits of throwaway prototyping as a way of eliciting the 'true' user requirements and prototyping as an evolutionary development method.
Throwaway prototyping is effective for eliciting the 'true' user requirements, while prototyping as an evolutionary development method allows for iterative refinement and continuous improvement.
Throwaway prototyping involves creating a prototype quickly and then discarding it after gathering user feedback. This approach allows stakeholders to experience and interact with a tangible representation of the system early in the development process. By using the throwaway prototype as a communication tool, the development team can better understand the user requirements and make adjustments based on user feedback. It helps in discovering and refining the 'true' user requirements before proceeding to the actual development phase.
On the other hand, prototyping as an evolutionary development method focuses on building an initial prototype and then incrementally improving it through multiple iterations. This approach allows for continuous feedback and refinement, enabling the system to evolve gradually. As the prototype is refined and enhanced with each iteration, it becomes more aligned with the actual requirements and user expectations.
Both approaches have their merits. Throwaway prototyping is effective in the early stages of a project when there is a need to explore and validate user requirements. It allows for rapid feedback and helps uncover any misunderstandings or missing requirements. On the other hand, prototyping as an evolutionary development method is beneficial when the requirements are not fully known or may change over time. It provides flexibility and the ability to adapt and refine the system through iterative cycles.
In conclusion, throwaway prototyping is valuable for eliciting the 'true' user requirements, while prototyping as an evolutionary development method enables continuous improvement and adaptation. The choice between these approaches depends on the specific project context, time constraints, and the level of clarity in user requirements.

a) How do the ascending order Merge Sort algorithm and Quick Sort algorithm (upto first partition) work on the following data? i- \( y p z \times r s \) Here, \( x= \) last two digits of your student
To analyze how the ascending order Merge Sort and Quick Sort algorithms work on the given data "y p z × r s" (where x represents the last two digits of your student number), we need to understand the basic concepts of these sorting algorithms.
1) Merge Sort:
Merge Sort is a divide-and-conquer algorithm that divides the input array into two halves, sorts them recursively, and then merges the sorted halves to obtain the final sorted array. The main steps of the Merge Sort algorithm are as follows:
a) Divide the array into two halves.
b) Recursively sort the two halves.
c) Merge the sorted halves into a single sorted array.
Using the given data "y p z × r s," we perform the Merge Sort algorithm as follows:
Step 1: Split the data into individual elements: "y", "p", "z", "×", "r", "s".
Step 2: Merge pairs of elements in ascending order: "p y", "× z", "r s".
Step 3: Merge the pairs again to obtain the final sorted array: "p × r s y z".
The final sorted array using Merge Sort is "p × r s y z".
2) Quick Sort:
Quick Sort is another efficient sorting algorithm that follows the divide-and-conquer approach. It selects a pivot element, partitions the array around the pivot, and recursively sorts the sub-arrays. The main steps of the Quick Sort algorithm are as follows:
a) Select a pivot element from the array.
b) Partition the array into two sub-arrays, such that elements smaller than the pivot are on the left, and elements greater than the pivot are on the right.
c) Recursively apply Quick Sort to the left and right sub-arrays.
Using the given data "y p z × r s," we perform the Quick Sort algorithm (up to the first partition) as follows:
Step 1: Select a pivot element (let's say the first element "y").
Step 2: Partition the array around the pivot "y":
- Elements smaller than "y": "p", "z", "×", "r", "s".
- Elements greater than "y": (none).
Step 3: The first partition is complete. The array becomes "p z × r s y".
After the first partition, the Quick Sort algorithm would proceed recursively to sort the left and right sub-arrays, but since we only considered the first partition, the sorting process is not complete.
