Is it the same as this C snippet?

  main() { while (1) printf("%c", rand()%2 ? '/' : '\\'); }

Edit: Golfed my original snippet down, then put back original after mmphosis's identical translation.

Small variant:

void main() { while (1) printf("%c", "/\\"[rand()%2] ); }

yes.

  #include <stdio.h>
  main() { for(;;) printf(rand()%2 ? "/" : "\\"); }

i think the key point is that / and \ do not span their character cells from corner to corner.
