Okay, that seems *really* silly to me! Why make a
subroutine call? Why re-test at the end what you know?
If it can be remembered that C is really a portable
assembly language, you will program in a "structured"
assembly style. Use the language:

  int a[100];
  int x, v;

  for (x = sizeof(a) / sizeof(a[0]); x >= 0; x--) {
    if (a[x] == v) {
      goto foundv;
    }
  }

  damn;

foundv:
  cool;

:)

Goto is not bad, programmers that misuse goto are bad.
