[Solved] Passing argument to sub-functions in C

by


only main can accept arguments from the command line (argv). if you want to pass these command line args to a function then you need to pass them as a paramater. 

#include <stdio.h>

int passingvars(int argc, char **argv)
{
    int i = 0;
    while (i < argc)
    {
        printf(argv[i]);
        i++;
    }
}

int main(int argc, char *argv[])
{
    passingvars(argc, argv);
    return 0;
}
