Thread: program arguments

Ok, I'm stuck again.

I'm want my program to accept different arguments from the command line, but haven't been able to get it to work. I want something like . . .

Code:

#include <stdio.h>
int main( int argc, char *argv[] )  
{
	if( argv[1] == "-h" )
        {
		printf("This is the help message");
        }
        return 0;

}

I also tried using a switch statement, but no luck so far. Any help would be appreciated. Thanks.

You may want to check out the usage of getopt().

Thanks.
Here's what I finally got to work!

Code:

#include <stdio.h>

int main(int argc, char *argv[])
{
	switch(argc)
	{
		case 2: 
			if (strcmp(argv[1], "-h") == 0)
			{
				printf("This is the help message!\n");
			}
			break;
	}
	return 0; 
 }
