Assume the existence of a Window class with a function getWidth that returns the width of the window. Define a derived class Win

Pepsi [2]

Answer:

Following are the code in the C++ Programming Language.

//define class and inherited the parent class

class WindowWithBorder : public Window

{

//access modifier

private:

//set integer variable

int borderWidth;

//set integer variable

int windowWidth;

//access modifier

public:

//definition of the constructor that accept an integer type argument

WindowWithBorder(int);

//definition of the function

int getUseableWidth();

};

//set constructor outside the class

WindowWithBorder::WindowWithBorder(int y)

{

//initialization in integer variable from function

windowWidth = getWidth();

//initialization in integer variable from the argument list

borderWidth = y;

}

//set function from outside the class

int WindowWithBorder::getUseableWidth()

{

//return output

return windowWidth - borderWidth;

}

Explanation:

Here we define a class "WindowWithBorder" which inherit their parent class "Window", inside the class.

Set two integer data type private variables "borderWidth" and "windowWidth".
Write the definition of the "windowWidth" class constructor that accept the integer type argument list.
Write the definition of the function "getUseableWidth()" which is integer type.

Then, we define constructor outside the class which accept the integer type argument list "y" inside it.

we initialize in the variable "windowWidth" from the function "getWidth()".
Initialize in the variable "borderWidth" from the argument of the constructor.

Finally, we define function in which we perform the subtraction of the variable "windowWidth" from the variable "borderWidth" and return it.

Write a static method that implements a recursive formula for factorials. Place this method in a test program that allows the us

matrenka [14]

Answer:

Written in Java

import java.util.*;

public class Main {

public static int fact(int n) {

if (n == 1)

return n;

else

return n * fact(n - 1);

}

public static void main(String[] args) {

int num;

Scanner input = new Scanner(System.in);

char tryagain = 'y';

while(tryagain == 'y'){

System.out.print("Number: ");

num = input.nextInt();

System.out.println(num+"! = "+ fact(num));

System.out.print("Try another input? y/n : ");

tryagain = input.next().charAt(0);

}

Explanation:

The static method is defines here

public static int fact(int n) {

This checks if n is 1. If yes, it returns 1

if (n == 1)

return n;

If otherwise, it returns the factorial of n, recursively

else

return n * fact(n - 1);

}

The main method starts here. Where the user can continue executing different values of n. The program keep prompting user to try again for another number until user signals for stoppage

public static void main(String[] args) {

This declares num as integer

int num;

Scanner input = new Scanner(System.in);

This initializes tryagain as y

char tryagain = 'y';

This checks if user wants to check the factorial of a number

while(tryagain == 'y'){

This prompts user for input

System.out.print("Number: ");

This gets user input

num = input.nextInt();

This passes user input to the function and also prints the result

System.out.println(num+"! = "+ fact(num));

This prompts user to try again for another value

System.out.print("Try another input? y/n : ");

This gets user response

tryagain = input.next().charAt(0);

}

Write a pyhton program to calculate area of a circle?

marta [7]

Answer:

The code to calculate the area of a circle is:

from math import pi

def circleArea(radius):

if radius > 0:

return pi * (radius ** 2)

else:

return None

if __name__ == '__main__':

radius = 5

print("Radius: {} Area: {}".format(radius,circleArea(radius)))

Explanation:

A detailed explanation of each line of code is given below.

#Define the number pi used to calculate the area

from math import pi

#We define a function that calculates the area of a circle

def circleArea(radius):

#Check if the radius is valid ( radius > 0) since there aren´t negative radius

if radius > 0:

#Compute the area formula for a circle $\pi * radius^{2}$

return pi * (radius ** 2)

else:

#Return None if the radius is invalid

return None

#Run the function we´ve defined

if __name__ == '__main__':

#Define a radius

radius = 5

#Call the function and parse the radius through it, then print the result

print("Radius: {} Area: {}".format(radius,circleArea(radius)))

cricket20 [7]

The components that is responsible for providing instructions and processing for a computer is a. CPU.

<h3>What area of the computer executes commands?</h3>

This command center's central processing unit (CPU) is a sophisticated, large-scale collection of electrical circuitry that carries out pre-stored program instructions. A central processing unit is a must for all computers, big and small.

Note that the CPU, RAM, and ROM chips are all located on the motherboard. The "brain" of the computer is known as the Central Processing Unit (CPU). It carries out instructions (from software) and directs other parts.
