return statement

[Macthecreator]

what is the difference between
return;
or return NULL;

[MikeyBoy]

The first doesn't return anything.

The second returns the value NULL.

The first one is handy for returning from a void function early, but I wouldn't bother for a void function that returns at the end like normal.

For the second one, C++11 has nullptr.

Hope all goes well.
