What is a neat way of breaking out of many for loops at once?

Question

Suppose I need to break out of three or four nested for loops at once at the occurence of some event inside the innermost loop. What is a neat way of doing that?

Answer 1

I'd do something like:

  int i, j, k;

  for (i = 0; i < 100; i++) {
      for (j = 0; j < 100; j++) {
          for (k = 0; k < 100; k++) {
              if (k == 50) {
                  return;
              }
          }
      }
  }
