Answer 1

From method names, I am compelled to believe you are creating some sort of a Lexer object. Generally you implement Lexer with stratified design. First consumption of characters, then tokens (made out of characters), then optionally constructs made out of tokens.

Hope this helps.

3. When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested?

A. Series

B. Parallel

C. Control

D. Line

Answers

Answer:

B. Parallel

Explanation:

When using the ohmmeter function of a digital multimeter, the leads are placed parallel to the component being tested. The digital multimeter is placed parallel to the component because, current has to flow into the component so as to be able to measure its resistance. Without the flow of current in the component, the resistance could not be measured.

If the component were placed in series, there would be no way to close the circuit because, we need a closed circuit so as to measure the resistance and use the ohmmeter function of the digital multimeter.

Only a parallel connection would close the circuit.

So, B is the answer.

Your dashboard should show the sum and average as two separate columns. If you use measure names as the column field, what should you use for the marks

Answers

Answer:

Hence the answer is a sum.

Explanation:

Here the statement shows that the dashboard should show the sum and average as two separate columns if we name measure names because the column field then for marks we'll use the sum. Since the sum displays the sum of the values of all the fields, which refers to the marks of the person.

Therefore the answer is a sum.

If we use measure names as the column field, we should use "the sum".

A set of cells that are support equipment on about a similar vertical line, is considered as a column.

Usually, the name of the user or a client represents a field column, while the total and sometimes even averaging columns in our dashboards or screen are different.When using a summation of total summary, perhaps the column field (title), as well as its amount and averaging marking, are indicated.

The preceding reply is thus right.

Write a program that reads a list of integers, and outputs those integers in reverse. The input begins with an integer indicating the number of integers that follow. For coding simplicity, follow each output integer by a comma, including the last one.Ex: If the input is:5 2 4 6 8 10the output is:10,8,6,4,2,To achieve the above, first read the integers into a vector. Then output the vector in reverse.

Answers

Answer:

The program in C++ is as follows:

#include <iostream>

#include <vector>

using namespace std;

int main(){

   vector<int> intVect;

   int n;

   cin>>n;

int intInp;

for (int i = 0; i < n; i++) {

 cin >> intInp;

 intVect.push_back(intInp); }

for (int i = n-1; i >=0; i--) {  cout << intVect[i] << " "; }

 return 0;

}

Explanation:

This declares the vector

   vector<int> intVect;

This declares n as integer; which represents the number of inputs

   int n;

This gets input for n

   cin>>n;

This declares intInp as integer; it is used to get input to the vector

int intInp;

This iterates from 0 to n-1

for (int i = 0; i < n; i++) {

This gets each input

 cin >> intInp;

This passes the input to the vector

 intVect.push_back(intInp); }

This iterates from n - 1 to 0; i.e. in reverse and printe the vector elements in reverse

for (int i = n-1; i >=0; i--) {  cout << intVect[i] << " "; }

Answers

Answer:

5) I and III only

Explanation:

From the declarations listed both declarations I and III will not permit calling the doSomething() method. This is because in declaration I you are creating a superclass variable but initializing the subclass. In declaration III you are doing the opposite, which would work in Java but only if you cast the subclass to the superclass that you are initializing the variable with. Therefore, in these options the only viable one that will work without error will be II.

you are installing two new hard drives into your network attached storage device your director asks that they be put into a raid solution that offers redundndancy over performance which would you use

Answers

Question options:

a. RAID 0

b. RAID 1

c. RAID 5

d. RAID 6

e. RAID 10

Answer:

d. RAID 6

Explanation:

RAID is Redundant Array of Inexpensive/Independent Disks. RAID combines low cost physical hard disk drives in one hard disk drive. RAID is used to achieve data redundancy(data backup but with synchronization) or improved performance or both.

To get what the director requires he would need to use RAID 6. RAID 6 is RAID level optimized to achieve data redundancy but with slow performance.

Coding 5 - Classes The Item class is defined for you. See the bottom of the file to see how we will run the code. Define a class ShoppingCart which supports the following functions: add_item(), get_total_price(), and print_summary(). Write code only where the three TODO's are. Below is the expected output: Added 2 Pizza(s) to Cart, at $13.12 each. Added 1 Soap(s) to Cart, at $2.25 each. Added 5 Cookie(s) to Cart, at $3.77 each.

Answers

Answer:

Explanation:

The following is written in Java. It creates the ShoppingCart class as requested and implements the requested methods. A test class has been added to the main method and the output is highlighted in red down below.

import java.util.ArrayList;

import java.util.Scanner;

class Brainly {

   public static void main(String[] args) {

       ShoppingCart newCart = new ShoppingCart();

       newCart.add_item();

       newCart.add_item();

       newCart.add_item();

       newCart.print_summary();

   }

}

class ShoppingCart {

   Scanner in = new Scanner(System.in);

   ArrayList<String> items = new ArrayList<>();

   ArrayList<Integer> amount = new ArrayList<>();

   ArrayList<Double> cost = new ArrayList<>();

   public ShoppingCart() {

   }

   public void add_item() {

       System.out.println("Enter Item:");

       this.items.add(this.in.next());

       System.out.println("Enter Item Amount:");

       this.amount.add(this.in.nextInt());

       System.out.println("Enter Cost Per Item:");

       this.cost.add(this.in.nextDouble());

   }

   public void get_total_price() {

       double total = 0;

       for (double price: cost) {

           total += price;

       }

       System.out.println("Total Cost: $" + total);

   }

   public void print_summary() {

       for (int i = 0; i < items.size(); i++) {

           System.out.println(amount.get(i) + " " + items.get(i) + " at " + cost.get(i) + " each.");

       }

       get_total_price();

   }

}

Preserving confidentiality, integrity, and availability is a restatement of the concern over interruption, interception, modification, and fabrication.
i. Briefly explain the 4 attacks: interruption, interception, modification, and fabrication.
ii. How do the first three security concepts relate to these four attacks

Answers

Answer and Explanation:

I and II answered

Interruption: interruption occurs when network is tampered with or communication between systems in a network is obstructed for illegitimate purposes.

Interception: interception occurs when data sent between systems is intercepted such that the message sent to another system is seen by an unauthorized user before it reaches destination. Interception violates confidentiality of a message.

Modification: modification occurs when data sent from a system to another system on the network is altered by an authorized user before it reaches it's destination. Modification attacks violate integrity, confidentiality and authenticity of a message.

Fabrication: fabrication occurs when an unauthorized user poses as a valid user and sends a fake message to a system in the network. Fabrication violates confidentiality, integrity and authenticity.

Write a class Example() such that it has a method that gives the difference between the size of strings when the '-' (subtraction) symbol is used between the two objects of the class. Additionally, implement a method that returns True if object 1 is greater than object 2 and False otherwise when the (>) (greater than) symbol is used. For example: obj1

Answers

Answer:

Here the code is given as follows,

Explanation:

class Example:

   def _init_(self, val):

       self.val = val

   def _gt_(self, other):

       return self.val > other.val

   def _sub_(self,other):

       return abs(len(self.val) - len(other.val))

def main():

   obj1 = Example('this is a string')

   obj2 = Example('this is another one')

   print(obj1 > obj2)

   print(obj1 - obj2)

main()

Output:-

Write a class called Student that has two private data members - the student's name and grade. It should have an init method that takes two values and uses them to initialize the data members. It should have a get_grade method.

Answers

Answer:

Explanation:

The following class is written in Python as it is the language that uses the init method. The class contains all of the data members as requested as well as the init and get_grade method. It also contains a setter method for both data variables and a get_name method as well. The code can also be seen in the attached image below.

class Student:

   _name = ""

   _grade = ""

   def __init__(self, name, grade):

       self._name = name

       self._grade = grade

   def set_name(self, name):

       self._name = name

   def set_grade(self, grade):

       self._grade = grade

   def get_name(self):

       return self._name

   def get_grade(self):

       return self._grade
