How to use 'break' jump out of 3 nested loop?
PostPosted: Wed Jun 01, 2011 9:28 am     Reply with quote
Hi

I want to use 'break' jump out of loops. The code in below.
Code:

while(condition1)
{
   while(condition2)
   {
      while(condition3)
      {
           if(condition)
           {
               break;
           }
      }//loop3
         dosomething3();
    }//loop2
         dosomething2();
}//loop1
dosomething1();


So after break is happened, which line is going to be executed.
Thanks.

'break', always exits the innermost loop only.
What will be executed, will depend on what condition2, and condiftion1 evaluate to.
Normal method:
Code:

int1 exit=FALSE;

while(condition1 && (exit==FALSE))
{
   while(condition2 && (exit==FALSE))
   {
      while(condition3 && (exit==FALSE))
      {
           if(condition)
           {
               exit=TRUE;
           }
      }//loop3
         dosomething3();
    }//loop2
         dosomething2();
}//loop1
dosomething1();

This way you can design your code to exit as many levels as you want.

Best Wishes

If you don't apply for a good coding style award, you'll notice, that a simple goto will save both text lines and code space. Smile
