How "break" works

[lestatgirl666]

Hi,

My doubt is the funcionality of the "break".

It is used mainly for switch control structure, but in other cases, a lot of people use it into a function and in while loops, with an if structure.

What does it really do?

Thanks a lot.

break is used to exit a switch statement or a loop (for, while, do/while statements).

Thanks,
but what happens if you have a while inside another, it exits only one level? Or in case you have an if-else clause inside a while loop?

break does not affect if/else, nor they it.
break will skip you out of only one level of loop.

You can't use break to exit from a loop if you use it in a switch statement either, since it will just exit from the switch statement.

Thanks a lot :)

Next I have an example where the break is used into a while working into a switch.

The declaration of i isn't quite right in that example.
