AGH!

USE A DIFFERENT NAME FOR YOUR CHAR VARIABLE.

Sorry, I can't believe no one's caught this yet. You can't use operator as the name of your char variable, because operator== is a function call for classes. Your compiler thinks you are calling the function operator== in every if statement, and then complains at the fact that there's no object, no parentheses, and no argument. Change the name to oper and see if it works.

It was caught (or at least different) in his other thread. There are three floating around now, I haven't gotten around to cleaning them all up.

I'm not sure if this is the 3rd or 4th time you've asked for help on this question, but before you proceed any further, could you take a good look at our Posting Guidelines, specifically the portion entitled Do Not Double Post your Questions.

Yes AGH!!!
I thought about that the name might be the problem at least 5 times but I couldn't figure out why so I always ignored it.

P.S. The O/P made it really confusing with double posting.
