Upload the source code (.cpp) of your applications. Upload a separate (.cpp) file for each question.

1-Create a C++ program which adds two numbers and displays the sum.

2-Create a C++ program which calculates and displays the area of a rectangle.

3-Create a C++ program which calculates and displays the average of four numbers..

4-Complete questions 3 of the chapter 3 Programming Exercises in pages 182 of the Textbook.

Upload your source codes to this link.

Answer 1

I don't have Visual Studio 2019 the program is the same only compile and running is different.

1- C++ program which adds two numbers and displays the sum

#include <iostream>
using namespace std;

//Declarating Num1/Num2 is an Integer
int addition(int Num1,int Num2);

int main()
{
        int Num1,Num2;
        int add;
        
        cout<<"Enter first number: ";
        cin>>Num1;
        cout<<"Enter second number: ";
        cin>>Num2;
        
        add=addition(Num1,Num2);
        
        cout<<"Sum of two number is: "<<add<<endl;
        
        return 0;
}
int addition(int Num1,int Num2)
{
        return (Num1+Num2);
}

Output:-

2- C++ program which calculates and displays the area of a rectangle.

#include <iostream>
using namespace std;

    int main()
    {
        int width, length, area;
                cout << "\n Find the Area of a Rectangle \n";     
        cout<<" Length of the rectangle : ";
        cin>>length;
                cout<<" Width of the rectangle : ";
        cin>>width;
        area=(length*width);
        cout<<" The area of the rectangle is : "<< area << endl;      
        cout << endl;
        return 0;
    }

Output:-

3- C++ program which calculates and displays the average of four numbers

#include<iostream>
using namespace std;
int main()
{

  double num1, num2, num3, num4;
  double sum, average;


  cout << "Enter Four Numbers :: ";
  cin >> num1 >> num2 >> num3>>num4;
  sum = num1 + num2 + num3 + num4;
  

  average = sum / 4;


  cout << "Sum = " << sum << endl;
  cout << "Average = " << average << endl;

  return 0;
}
