Thread: help

I am new to C and can't get my program to work. What is suposed to happen is at the command line I enter my program name and one argument. For example lets call my program myprog.

myprog 3

now after entering that it should spit out 4 (argv[1] + 1 = 4).

so all to gether it should look like this

myprog 3
4

But it dosent do that instead it does this.

myprog 3
-1073742996

Now thats not right.

When I compile there are no errors or warnings so
I cant figure it out. here is the source. If somenone
could correct it then repost it that would be great
thanks!

#include <stdio.h>

int main(int argc, int argv[])
{
	int hex;	

	if(argc == 2)
	{
		hex = dec2hex(argv[1]);
		printf("%i\n", hex);
	}
	else if(argc == 1)
	{
		printf("Error: no arguments\n");
	}
	else
	{
		printf("Error: too many arguments\n");
	}

	return 1;
}

int dec2hex(int dec)
{
	return dec + 1;
}
