Answers

Inheritance in object-oriented programming is a mechanism where one class is derived from another class to acquire its properties, methods, and fields.

The class that is inherited from is called the parent or base class, and the class that inherits is called the child or derived class.

Here are four types of inheritance in C++ programming language.

1. Single inheritance: Single inheritance is a type of inheritance where one class is derived from a single parent or base class. It allows one class to inherit properties and methods from another class.

Example:```class Animal{public:void eat(){ cout << "Eating...";}};class Cat : public Animal{public:void meow(){ cout << "Meowing...";}};```

2. Multiple inheritance: Multiple inheritances is a type of inheritance where a class is derived from more than one base class. It allows the derived class to inherit the properties and methods of multiple classes.

Example:```class A{public:void displayA(){ cout << "A...";}};class B{public:void displayB(){ cout << "B...";}};class C : public A, public B{public:void displayC(){ cout << "C...";}};```

3. Multilevel inheritance; Multilevel inheritance is a type of inheritance where a derived class is derived from another derived class. It allows a class to inherit properties and methods from more than one base class

.Example:```class A{public:void displayA(){ cout << "A...";}};class B : public A{public:void displayB(){ cout << "B...";}};class C : public B{public:void displayC(){ cout << "C...";}};```

4. Hierarchical inheritance; Hierarchical inheritance is a type of inheritance where more than one class is derived from a single base or parent class.

It allows multiple derived classes to inherit the properties and methods of a single base class.

Example:```class Animal{public:void eat(){ cout << "Eating...";}};class Cat : public Animal{public:void meow(){ cout << "Meowing...";}};class Dog : public Animal{public:void bark(){ cout << "Barking...";}};```

18) Construct an argument using rules of inference to show that
the hypotheses : "It is not sunny this afternoon and it is colder
than yesterday. We will go swimming only if it is sunny. If we do
no

Answers

By using the rules of inference, we can construct an argument to show that the given hypotheses lead to the conclusion: "We will not go swimming this afternoon."

To construct the argument, we can use logical rules of inference to derive the conclusion based on the given hypotheses. Let's analyze the premises and apply logical reasoning to establish the conclusion.

It is not sunny this afternoon and it is colder than yesterday.

We will go swimming only if it is sunny.

If we do not go swimming, we will do some other outdoor activity.

From the first premise, we know that it is not sunny this afternoon and it is colder than yesterday. This can be represented as ¬Sunny ∧ Colder.

From the second premise, we understand that we will go swimming only if it is sunny. This can be represented as Sunny → Swimming.

From the third premise, we can deduce that if we do not go swimming, we will do some other outdoor activity. This can be represented as ¬Swimming → Outdoor activity.

Now, let's apply the modus tollens inference rule:

From premise 2, using the modus tollens rule, we can infer ¬Sunny, as ¬Swimming is true.

Combining ¬Sunny with the first premise, we have ¬Sunny ∧ Colder.

From the conjunction of ¬Sunny and Colder, we can deduce Colder.

Therefore, based on the logical reasoning, we can conclude that it is colder than yesterday, and hence, we will not go swimming this afternoon.

1. Define class and objects with example program of four basic arithmetic operations. 2. Define virtual function with an example program of four basic arithmetic operations.

Answers

In object-oriented programming, a class is a blueprint or template that defines the properties and behaviors of objects. An object, on the other hand, is an instance of a class. This allows for modular and reusable code. In the context of the four basic arithmetic operations, a class can be defined to encapsulate the logic and behavior of performing these operations, while objects can be created from the class to perform specific arithmetic calculations.

In the first program, the four basic arithmetic operations (addition, subtraction, multiplication, and division) can be implemented as member functions within a class. The class can have member variables to store the operands and member functions to perform the operations. Objects can then be created from this class to perform arithmetic calculations.

In the second program, virtual functions can be used to implement polymorphism, which allows for different behavior based on the type of the object. By defining a base class with virtual functions for the arithmetic operations, derived classes can override these virtual functions to provide specific implementations. This enables dynamic binding, where the appropriate implementation is determined at runtime based on the actual type of the object.

Both approaches demonstrate the concept of encapsulating functionality within a class and creating objects to perform specific operations. The first program focuses on the basic implementation of arithmetic operations within a class, while the second program showcases the usage of virtual functions and polymorphism to achieve dynamic behavior based on object types.

Separation of duties as a security tool is a good practice and should be implemented to the greatest extent possible, Separation of duties is a principle employed in many organizations to ensure that no single individual has the ability to conduct transactions alone.

Answers

The false statement when discussing separation of duties is "Separation of duties as a security tool is a good practice and should be implemented to the greatest extent possible."

Separation of duties is an important principle in organizations to ensure that no single individual has too much control or authority over critical functions or processes. By spreading responsibilities across different individuals, the organization reduces the risk of fraud, errors, and abuse. While separation of duties is generally considered a good practice and should be implemented to the extent possible, it may not always be feasible or practical in certain situations. There may be limitations due to resource constraints, the size of the organization, or the nature of certain roles. In some cases, implementing strict separation of duties may introduce unnecessary complexity or hinder operational efficiency.

Matplotlib Assignment 1. explain and give example of 'equal axis
aspect ratio'

Answers

The 'equal' axis aspect ratio in Matplotlib refers to setting the x-axis and y-axis scales to be equal, ensuring proportional representation of data.

An example is using plt.axis('equal') or aspect='equal' when plotting to achieve equal axis aspect ratio. In Matplotlib, the 'equal' axis aspect ratio is ensuring that the plotted data appears in proportion without any distortion. This means that one unit on the x-axis will have the same length as one unit on the y-axis.

To achieve equal axis aspect ratio in Matplotlib, you can use the plt.axis('equal') function or set the aspect parameter to 'equal' when plotting.

Here's an example:

python

import matplotlib.pyplot as plt

# Sample data

x = [1, 2, 3, 4]

y = [2, 4, 6, 8]

# Plot the data with equal axis aspect ratio

plt.plot(x, y)

plt.axis('equal')

# Add labels and title

plt.xlabel('X-axis')

plt.ylabel('Y-axis')

plt.title('Equal Axis Aspect Ratio')

# Display the plot

plt.show()

In this example, the plt.axis('equal') function ensures that the x-axis and y-axis have the same scale, resulting in a plot where the units are represented equally.

b) Write the Java code for the Pet class.

Answers

The Pet class represents a pet with fields for name, animal type, and age. It provides methods to set and retrieve these fields.

Here is the UML diagram for the Pet class:

Arduino Code:

------------------------------------------

| Pet |

------------------------------------------

| - name: String |

| - animal: String |

| - age: int |

------------------------------------------

| + setName(name: String): void |

| + setAnimal(animal: String): void |

| + setAge(age: int): void |

| + getName(): String |

| + getAnimal(): String |

| + getAge(): int |

------------------------------------------

In the Java code implementation, we define the class "Pet" with private fields for name, animal, and age. These fields are accessed through public getter and setter methods. The setter methods (setName, setAnimal, and setAge) take parameters representing the new values for the respective fields and do not return a value (void). The getter methods (getName, getAnimal, and getAge) retrieve the values of the fields and return them. For example:

Java Code:

public class Pet {

private String name;

private String animal;

private int age;

public void setName(String name) {

this.name = name;

}

public void setAnimal(String animal) {

this.animal = animal;

}

public void setAge(int age) {

this.age = age;

}

public String getName() {

return name;

}

public String getAnimal() {

return animal;

}

public int getAge() {

return age;

}

What is the minimal number of edges that have to be deleted from K3,5 (the complete bipartite graph three-by-five vertices) in order to get a planar graph
OA. 6 OB. 5 O. C. 4 OD. 3 OE 2

Answers

The minimal number of edges that have to be deleted from K3,5 in order to get a planar graph is C. 4.

To determine the minimal number of edges that need to be deleted from K3,5 (a complete bipartite graph with three vertices in one set and five vertices in the other set) to obtain a planar graph, we can make use of Euler's formula. Euler's formula states that for a planar graph, the number of vertices (V), edges (E), and faces (F) are related by the equation V - E + F = 2.

In the case of K3,5, it has a total of 8 vertices (3 + 5) and 15 edges (3 * 5). Since we want to transform it into a planar graph, we need to remove edges in such a way that it satisfies Euler's formula.

If we remove fewer than 4 edges, the number of edges would still be greater than the number of vertices minus 2, and therefore, it would not be planar. On the other hand, removing exactly 4 edges reduces the number of edges to 11, which is equal to the number of vertices minus 2, satisfying Euler's formula.

Therefore, the minimal number of edges that have to be deleted from K3,5 to obtain a planar graph is C. 4.

Yes, f(n) = 5n^2 - 5n is O(n^2). The highest power of n in the equation is n^2, indicating that the growth rate of f(n) is proportional to n^2.

Big-O notation is used to analyze the time complexity of algorithms and functions. To determine if f(n) = 5n^2 - 5n is O(n^2), we need to compare the growth rate of the function to n^2.

In f(n) = 5n^2 - 5n, the highest power of n is 2, and the coefficient of n^2 is 5. In Big-O notation, we ignore the lower order terms and the coefficients, focusing only on the term with the highest power of n. Therefore, we can say that f(n) is O(n^2).

When we say f(n) = O(n^2), it means that the growth rate of f(n) is at most quadratic. As n increases, the impact of the lower order terms and coefficients becomes negligible compared to the dominant term, which is n^2.

By definition, for a function f(n) to be O(g(n)), there exists a positive constant c and a positive integer n0 such that for all n ≥ n0, f(n) ≤ c * g(n). In the case of f(n) = 5n^2 - 5n, we can choose c = 6 and n0 = 1. For all n ≥ 1, 5n^2 - 5n ≤ 6n^2.

Therefore, f(n) = 5n^2 - 5n is O(n^2).

Identify and correct the-syntax and logical- errors in each of the following statements. (NOTE: There could be more than on error) 1) float numberl, number2; scanf("%d%d", number1, number2); int x=129;y=323, z; z=x+y; Printf("The sum of %d and %d is :x+y ",x,y, z); 3) int x=5, y=5,r; x*x + y*y= x; I 2)

Answers

The final corrected statement is as follows:```float number1, number2;scanf("%f%f", &number1, &number2);int x=129,y=323,z;z=x+y;printf("The sum of %d and %d is : %d", x, y, z);int x=5, y=5, r;x = x*x + y*y;```

The first statement has the following errors:Syntax Error: The statement `float numberl, number2;` has an error because the first variable `numberl` is misspelt. It should be `number1`. Also, the semicolon should be removed because the second variable `number2` is on the same line.Logical Error: The `scanf()` statement is incomplete. The variables `number1` and `number2` should have an ampersand sign `&` before them to indicate their memory addresses. The correct statement is: `scanf("%f%f", &number1, &number2);`. Also, the last argument of the `printf()` statement is incorrect because it does not display the sum of `x` and `y`. It should be: `printf("The sum of %d and %d is : %d", x, y, z);`.Therefore, the corrected statement is as follows:```float number1, number2;scanf("%f%f", &number1, &number2);int x=129,y=323,z;z=x+y;printf("The sum of %d and %d is : %d", x, y, z);```The second statement has the following errors:Syntax Error: There is no syntax error in the statement.Logical Error: The statement `x*x + y*y= x;` has an error because the left-hand side is an expression and cannot be assigned to a variable. Also, the variable `r` is declared but not used. Therefore, the corrected statement is:```int x=5, y=5, r;x = x*x + y*y;```

To realize the code in C/C++ programming, you would need to define the functions for the ODEs, implement the Runge-Kutta 4th order method, and calculate the error at the right end of the interval for different step sizes. The specific implementation details would depend on the programming language and libraries you are using.

The explicit one-dimensional Runge-Kutta 4th order method is a numerical method used to approximate the solution of ordinary differential equations (ODEs). It is known for its accuracy and efficiency in solving ODEs. The method calculates the solution by evaluating a set of intermediate stages based on the slope of the ODE at different points.

The numerical implementation of the method involves the following steps:

Define the ODE dx/dt as a function f(t, x) that returns the derivative of x with respect to t.

Choose the initial conditions, such as the initial value x(0) and the integration interval [a, b].

Choose a step size h, which determines the spacing between the points at which the ODE is evaluated.

Initialize the variables t and x to the initial values.

Repeat the following steps until t reaches the end of the interval:

a) Calculate the intermediate stages k₁, k₂, k₃, and k₄ using the formulas derived from the Runge-Kutta method.

b) Update x based on the weighted sum of the intermediate stages.

c) Update t by incrementing it with the step size h.

Output the values of x at different time points as the approximate solution.

Here are the examples of integration using the Runge-Kutta 4th order method:

a) For dx/dt = t on the segment [0, 1] with x(0) = 0:

The exact analytic solution is x = t²/2.
