out of mutil-cyle

how to out the multi-cycle in C
we all know the key-word break;
but it can only out one cycle, if we want to out multi-cycle, how we do ?

method 1:
  use goto
method 2:
  use a variable to store the state, if the state can meet, then we break; else we not, just like this
  int whether_out = 0;
  .......
  {
     whether_out = 1;
  }
  if (whether_out = 1)
          break;
method 3:
   we all know that when we do loop, we will determin
the cycle-conditions, we in the inner cycle, we can change the cycle-conditions to break out the cycle.
it like this
  for (i = 0; i < max_i; i++)
{
   for( j = 0; j < max_j; j++)
   {
     .......
     ........
     i = max_i;
   }
}
