Write a C program to calculate difference of two numbers

Below is the source code for C program to calculate difference of two numbers which is successfully compiled and run on Windows System to produce desired output as shown below :

SOURCE CODE : :

/*  C program to calculate difference of two numbers  */

#include <stdio.h>

int main()
{

    int a,b;
    int diff;

    printf("Enter first number :: ");
    scanf("%d",&a);
    printf("\nEnter second number :: ");
    scanf("%d",&b);

    // check condition to identify which is largest number
    if( a>b )
        diff=a-b;
    else
        diff=b-a;

    printf("\nDifference between %d and %d is = %d\n",a,b,diff);
    return 0;
}

OUTPUT : :

************** First Run ******************
    
Enter first number :: 6

Enter second number :: 2

Difference between 6 and 2 is = 4


************** Second Run ******************

Enter first number :: 7

Enter second number :: 45

Difference between 7 and 45 is = 38

Above is the source code for C program to calculate difference of two numbers which is successfully compiled and run on Windows System.The Output of the program is shown above .
