C++ Question

what is this mean ? in C++ for example

line <line2 ? line : line1;

Code:

a<=b?cout<<"a is less then b":cout<<"b is less then a";

Can also be written as:

Code:

if(a<=b)
{
    cout<<"a is less then or equal to b";
}
else
{
    cout<<"b is less then a";
}

I use it to shorten stuff up

Anyway its what HD said. Just a shortened version of the if else statement...

[php]comparison1 < comparison2 ? Execute_If_True : Execute_If_False;[/php]

Try doing it this way. I just realised the shorthand version can only pass a values sort of forgot about that :l. So like this:

Code:

return (val1<val2) ? val1 : val2;
