"?" and ":"

[EvBladeRunnervE]

I was wondering what the "?" and ":" do when in code like this

12 ? 3 : 20

what does the "?" and ":" do in the previous code. I know its probably somewhere, but I am having trouble finding the answer.
Thanks in advance.

It will be true the result (Different of 0) cuz 12 is a number different of zero.

(condition) ? (do this if true) : (do this if false);

thanks, I could of sworn it had something to do with TRUE or FALSE.

A more accurate definition of what it does would probably be the whole expression becomes instead of do this

e.g.

int x;
bool y=true;
x=y?3+3:cout<<"This won't execute";

Of course it won't execute. That's C++ and this is a C board...
