Using "continue" (basic language problem)

If I have something like:

Code:

---

for(int i=0; i<100; i++)
{
  for(int n=0; n<100; n++)
  {
      if(n==i)
        continue;

      ... // more stuff
  }
  ... // more stuff
}

---

Can I, with a single line of code, make the "continue;" skip to the end of the outer loop (i.e. rather than just the loop it's in).

thanks in advance,

dt

Is not a single line, but...(Why you want a single-line solution anyway?)

Code:

---

bool found = false;
for ( int i = 0; i < 100; i++ )
{
  for ( int n = 0; n < 100; n++)
  {
      if ( n == i ) {
        found = true;
        continue;
      }

      ... // stuff to skip
  }
   
  if ( found )
        continue;
  ... // more stuff to skip
}

---

Or lookup "goto", never used that before so don't know how to use it ;)

Many thanks. That's what I've been doing, but I was wondering if there was a slimmer way of doing it as it's in a seriously nested loop which needs to be as efficient as possible. A single line solution would be great and I seem to remember seeing one for break, so I figured there'd be one for continue. I'm probably imagining things though!

dt

Well then lookup "goto", it'll be something like this

Code:

---

for ( int i = 0; i < 100; i++ )
{
  for ( int n = 0; n < 100; n++)
  {
      if ( n == i ) {
        goto LABEL_A;

      ... // stuff to skip
  }
 
  ... // more stuff to skip
  LABEL_A
}

---

I don't know the exact construction. And note that the use of "goto" is a sensitive issue so I don't know if this one is one of the correct implementations of "goto"

>And note that the use of "goto" is a sensitive issue
You can say that again. The ignorant masses tend to drive controversy. ;)

>so I don't know if this one is one of the correct implementations of "goto"
That is one of the "acceptable" uses. But using goto feels inelegant; I would spend a few grey cells trying to restructure the program so that it's unnecessary.

Thankyou Alphaoid. I agree with Prelude though, and I've just stuck with what I've got and slimmed everything else down as much as possible (just bought Effective C++ so on a mission ;). I got the 3-4 second loop in question, down to around half a second. It's amazing what crap you can write when you write code ad lib and without real design!
