the Ternary operator

[davez]

Can someone teach me how ternary operator works i really cant understand it. Thanks

In short, [cond]?[then]:[else] equals to

[return type] ternary()
{ 
    if([cond]) {
        return [then]
    } else {
        return [else]
    }
}

Main difference between if construction and ternary operator is that ternary operator returns value, so you can do things like:

int n;
std::cin >> n;
n = (n > 0?10:-10);

This sets n to 10 if user input positive value and -10 otherwise

[giblit]

n = (n > 0:10:-10); shouldn't this be n = n > 0 ? 10 : -10;
