 C program to find the difference between two numbers 

Note 

This is a comment written inside //. It does not have to be written while programming. The reason for using it is for the convenience and understanding of another programmer

Program

#include<stdio.h> #include<conio.h> void main() {    int a, b, d, c;    // taking input of first number    printf("\n Enter a first number");    scanf("%d",&a);    // taking input of second number    printf("\n Enter a second number");    scanf("%d",&b);    /* checking greatest number     when first number greater than second number */    if(a>b)    {    // subtracting second number from first number    d=a-b;    // printing difference    printf("\n Difference = %d", d);    // when second number is greater than first number     }    else    {    // subtracting first number from second number    c = b-a;    // printing difference    printf("\n Difference = %d", c);     }    getch(); }
