That's because operator= is the assignment operator in C++ (and most languages, actually). That changes the value of the variable to the value on the other side. So, for instance:

x = 0

will change the value of x to 0. Doesn't matter if it's in an if statement. It will always change the value to 0 (or whatever the right hand side value is).

What you are looking for is operator==, which is the comparison (aka relational) operator in C++/ That asks the question "Are these two things equal?" So, for instance:

x == 0

asks is x is equal to 0.
