Help with main function only allowed to declare variables and functions.

**machine392** · 03-10-2015

So I need to make a main function have no if/for/etc. statements so I need to move it to another function and call it in main. The problem is that it's a command line argument function so I'm confused on how it works. Here's an example:

Code:

#include <stdio.h>



int main(int argc, char* argv[])
{
printf("The program name %s", argv[0]);

if (argc == 2) {
    printf("Argument supplied is %s", argv[1]); }
else if (argc > 2) {
    printf("Too many arguments");}
else {
    printf("One argument");}

}

How can i make this into two functions with main only declaring variables and calling other functions?

You should pass argc and argv to a function that checks the command line arguments. You will probably still need an if statement in the main function though, i.e., this second function would return say, a boolean value to indicate if the checks were successful or failed, upon which in main you check the return value from calling this function to determine if the program should terminate or continue.

Sounds like you should take a look at Functions in C.
