Almost.  It should be:

	#include <stdio.h>
	#include <string.h>

	main(argc, argv)
		int argc; char *argv[];
	{
		char *ptr;

		if ((ptr = strchr(argv[1], '/')) == NULL)
			ptr = argv[1];
		else
			ptr++;

		puts(ptr);
	}

strchr can return NULL when there are no chars in the string that match
the char you are searching for.
