CPP Hacks.

For ages I've belived that one couldn't paste a "\" in front of a "n" in C and have it produce a newline (\n). Well, you can. This works:

#include <stdio.h>

#define slash() \ //slash

#define strize(x) #x
#define strevl(x) strize(x)

#define slashit(x) strevl(slash()x)

int main(void)
  {
    printf("[%s]\n", slashit(n));
  }

produces the output:

[
]

As one might hope.

It seems a bit friends-page-breaky. o_O

Wow, did it ever. It completely distorted my page when I went to look at it. Anyhow, it is now fixed.
