Sometimes, you need to exit a nested loop early, and the break; statement will only let you exit one level of a loop. Use a flag to indicate if the loop should be exited.

 bool abort = false;for(int i = 0; (i < 100) && (! abort); i++){   for(int j = 0; (j < 100) && (! abort); j++)   {      for(int k = 0; (k < 100) && (! abort); k++)      {         if(k == 15)         {             abort = true;             break;         }      }//end k loop.   }//end j loop.}//end i loop.if (abort){        // handle premature loop exit here}else{        // handle normal loop exit here}
