while loops . . .

Hey -

I had a simple question concerning while loops. I need to be able to have code inside a loop exit the loop when a certain condition is met. An example would be the VB code, "exit while". Is there a C++ equivilent? Thanks for your help . . .

It's usally advise to generate the exit condition rather than trying to force your way out of the loop, for example.

Code:

---

while (exit != True)
{
...
exit = True;
...
}

---

or

Code:

---

do
{
...
exit = true;
...
} while(exit != True)

---

Depending on how soon you want to exit, or test for a condition, you can use either a Pre-Test Loop, or a Post-Test loop.

but I think you can use

Code:

---

break;

---

Use the break keyword;
Example:

Code:

---

for( ; ; )    // No termination condition.
{
    if( List->AtEnd() )
        break;

    List->Next();
}

cout << "Control transfers to here.\n";
