In C-like languages exiting from a deeply nested loop isn’t exactly trivial (without the use of goto, so don’t even go there).

C++

exitloop = 0
for (i=1; i<=10 && !exitloop; i=i+1) {
   for (j=1; j<=10 && !exitloop; j=j+1) {
      for (k=1; k<=10 && !exitloop; k=k+1) {
         if (x[i][j][k] == 0) 
            exitloop = 1;
         }
      }
   }

for (i=1; i<=10; i=i+1) {
   for (j=1; j<=10; j=j+1) {
      for (k=1; k<=10; k=k+1) {
         if (x[i][j][k] == 0) 
            goto exitloop;
         }
      }

exitloop:
