break N

Will break out of a loop or switch N levels up.

Technically this can be done already in C with a goto statement, but this is syntactically more readable.

Examples

• SuperC
• C99
• Output

• #include <stdio.h>
  
  int main() {
    printf(" -- Begin --\n");
  
    for (int j = 0; j < 10; j++) {
      for (int i = 0; i < 10; i++) {
        if (i == 5 && j == 2)
          break 2; /* Break both for loops */
        printf(" %d\n", i);
      }
      putchar('\n');
    }
  
    printf("\n -- End --\n");
  
    // -- Begin --
    // 0 1 2 3 4 5 6 7 8 9
    // 0 1 2 3 4 5 6 7 8 9
    // 0 1 2 3 4
    // -- End --
    return 0;
  }
  

• #include <stdio.h>
  
  int main() {
    printf(" -- Begin --\n");
  
    for (int j = 0; j < 10; j++) {
      for (int i = 0; i < 10; i++) {
        if (i == 5 && j == 2)
          goto lbl_break2; /* Break both for loops */
        printf(" %d\n", i);
      }
      putchar('\n');
    }
  
    lbl_break2:
    printf("\n -- End --\n");
  
    // -- Begin --
    // 0 1 2 3 4 5 6 7 8 9
    // 0 1 2 3 4 5 6 7 8 9

•  -- Begin --
   0 1 2 3 4 5 6 7 8 9
   0 1 2 3 4 5 6 7 8 9
   0 1 2 3 4
