It depends on the way the script is called. For example, if you are using system you can preformat string that used to invoke bash script from system call adding command line arguments:

C

#include "stdio.h"

void main(int argc, char const *argv[])
{
    if (argc == 2) {
        char command[100] = {0};

        sprintf(command, "./example.sh %s", argv[1]);
        system(command);
    }
}

Bash

#!/bin/bash

echo $1

As a result

$ gcc example.c -o example && ./example Hello!
Hello!
