Question

Here is a schema of my code :

while (..)
{
   for (...; ...;...)
        for(...;...;...)
            if ( )
            {
                 ...
                 continue;
            }
} 

What will do the continue? He will only make the second loop iterate one time, no?
I would like it to reach the while, is it possible ?

Thanks!

Answer 1

The continue here impacts the nearest loop – your second for. There are two ways of jumping directly to the while:

• goto, although sometimes “considered harmful”, this is arguably the main reason why it still exists
• return

To illustrate the latter:

while (..)
{
    DoSomething(..);
}

void DoSomething(..) {
    for (...; ...;...)
      for(...;...;...)
          if ( )
          {
             ...
             return;
          }
}

and the former:

while (..)
{
   for (...; ...;...)
        for(...;...;...)
            if ( )
            {
                 ...
                 goto continueWhile;
            }
   continueWhile:
       { } // needs to be something after a label
}
