"break" - quick response needed

[luke]

can someone tell me which loop i'll break out of and where i'll end up?

for (I=0; I < spaceCounter; I++)
{
while (ptr2 != ptr1)
{
if (*ptr2 == ' ')
{
if (alternate == 1)
{
while (*ptr2 == ' ')
{
*ptr3++ = *ptr2++;
}
*ptr3++ = ' ';
alternate = 0;
break;
}
else
{
while (*ptr2 == ' ')
{
*ptr3++ = *ptr2++;
}
alternate = 1;
}
}
else
{
*ptr3++ = *ptr2++;
}
}
}

for (I=0; I < spaceCounter; I++) { 
    while (ptr2 != ptr1) { /*Breaks from this loop here*/
        if (*ptr2 == ' ') { 
            if (alternate == 1) { 
                while (*ptr2 == ' ') { 
                    *ptr3++ = *ptr2++; 
                } 
                *ptr3++ = ' '; 
                alternate = 0; 
                break; 
            } 
            else  { 
                while (*ptr2 == ' ') { 
                    *ptr3++ = *ptr2++; 
                } 
                alternate = 1; 
            } 
        } 
        else { 
            *ptr3++ = *ptr2++; 
        } 
    } 
}

if you layout your code PROPERLY, then you should see that it is the second loop

thanks for the reply, so do you mean the "while" loop?


ps
(i did lay it out properly, but it came out ****ed up after i posted it)

Fair enough, forgiven then. Next time put the code in tags [ code ] to open and [ /code ] to close. don't use tabs too. use spaces, it's a pain in the butt, i know.

and yes it is the while loop.

When you break from a nested loop, the break will only occur on the loop that you call it from. So if you have three loops nested inside each other, a break from the inner most loop will take you to the point in the second loop right after the inner loop.

while ( something ) {
  while ( somethingElse ) {
    while ( anotherSomething ) {
      break;
    }
    /* You end up here */
  }
}
