So you would expect that if operatorBar = 1, then OB will = 1, and operator will = 4. I know the first part is ok due to testing, but what happens when I run the program is that it acts like the if's don't exist, so upon using operators method operator will equal 5 no matter what. What's wrong here?

In C, a single = is an assignment; a double == is a check for equality.
