Program

Write a program that perform all arithmetic operation on two variable in C.

#include < stdio.h >

#include < conio.h >

void main()

{

     int x , y ;

     x = 2 ;

     y = 3 ;

     printf ( " %d + %d = %d \n " , x , y , x + y );

     printf ( " %d - %d = %d \n " , x , y , x - y );

     printf ( " %d * %d = %d \n " , x , y , x * y );

     printf ( " %d / %d = %d \n " , x , y , x / y );

}

Write a program that perform all arithmetic operation on two variable in C++.

#include < iostream >

using namespace std;

int main()

{

     int x , y ;

     x = 2 ;

     y = 3 ;

     cout << x << " + " << y << " = " << x + y ;

     cout << x << " - " << y << " = " << x - y ;

     cout << x << " * " << y << " = " << x * y ;

     cout << x << " / " << y << " = " << x / y ;

     return 0 ;

}

 

Output of the program 2 + 3 = 5 2 - 3 = -1 2 * 3 = 6 2 / 3 = 0

Write a program that converts 3.5 miles into kilometers and display the result on screen in C.

               ( Hint: 1 mile = 1.609 kilometers )

#include < stdio.h >

#include < conio.h >

void main()

{

     float miles , km ;

     miles = 3.5 ;

     km = miles * 1.609 ;

     printf ( " %f miles = %f  kilometers " , miles , km );

}

Write a program that converts 3.5 miles into kilometers and display the result on screen in C++.

               ( Hint: 1 mile = 1.609 kilometers )

#include < iostream >

using namespace std;

int main()

{

     float miles , km ;

     miles = 3.5 ;

     km = miles * 1.609 ;

     cout << miles << " miles = " << km << " kilometers " ;

     return 0 ;

}

Output of the program 3.5 miles = 5.6315 kilometers

Write a program that interchanges value of two variables using assignment values on the screen in C.

#include < stdio.h >

#include < conio.h >

void main()

{

     int x , y , temp ;

       x = 155 ;

    y = 40 ;

    printf ( " Values Before Interchange \n " ) ;

    printf ( " Value X = %d \n " , x ) ;

    printf ( " Value Y = %d \n " , y ) ;

    temp = x ;

    x = y ;

    y = temp ;

    printf ( " Values After Interchange \n " ) ;

    printf ( " Value X = %d \n " , x ) ;

    printf ( " Value Y = %d \n " , y ) ;

}

Write a program that interchanges value of two variables using assignment values on the screen in C++.

#include < iostream >

using namespace std;

int main()

{

     int x , y , temp ;

     x = 155 , y = 40 ;

     cout << " Values Before Interchange \n " ;

     cout << " Value X = " << x ;

     cout << " Value Y = " << y ;

     temp = x ;

     x = y ;

     y = temp ;

     cout << " Values After Interchange \n " ;

     cout << " Value X = " << x ;

     cout << " Value Y = " << y ;

     return 0 ;

}

Output of the program Values Before Interchange Value X = 155 Value Y = 40 Value After Interchange Value X = 40 Value Y = 155
