Add two numbers using Command line arguments in c

By
Source Code:

#include<stdio.h>
#include<stdlib.h>
void main(int argc , char * argv[])
{
    int i,sum=0;

    if(argc!=3)
      {
      printf("you have forgot to type numbers.");
      exit(1);
      }

    printf("The sum is : ");

    for(i=1;i<argc;i++)
        sum = sum + atoi(argv[i]);

    printf("%d",sum);

}

Output:

 D:\D INSTALL\TDM-GCC-32\Programs>add 2 4
The sum is : 6
D:\D INSTALL\TDM-GCC-32\Programs>add 5 4
