Accessing command line arguments in C -

-

please forgive me if noob question, i'm beginner @ c, learning while. tried write program sums 2 numbers (provided params application). code this:

#include <stdlib.h> #include <stdio.h>  int main( int argc, char** argv) {    int = atoi(argv[0]);    int b = atoi(argv[1]);    int sum = a+b;    printf("%d", sum);    return 0; }

but incorrect results - huge numbers small inputs 5 , 10. wrong here?

the first argument program name of program itself. try using following instead.

int = atoi(argv[1]);  int b = atoi(argv[2]);
