Ahhh, come on cpjust. Humour is fairly important in life... And, really, strfry might even be useful for those too lazy to actually code their own shuffle algorithm. And memfrob... Well, okay, that IS completely useless.
I think, however, that all hello world tutorials should be changed into this:
Code:
#define _GNU_SOURCE
#include <stdio.h>
#include <string.h>
int main()
{
char hello[] = "Hdellloorw!, ";
strfry(hello);
printf("%s\n", hello);
}
It may print hello world every once in a very long while.
