Thread: macro comparison syntax

For the line below, is there an easy way for me to add a 3rd condition for the case pos == actual_depth? What is the ? ... : ... called?

Code:

actual_depth += (pos > actual_depth ? 1: -1);

It's called the ternary operator. And it's possible like this:

Code:

actual_depth += (pos > actual_depth ? 1: (pos == actual_depth ? WHATEVER : -1));

Thanks for the answer and suggestion.
