IF/ELSE not working

Write your question here.
I am new at C++ and having problems with this code, it always takes the first option on the IF even if I hardcode the option to a different number, any ideas?

You are doing assignment in your if statement checks. Use == for comparison.

Shows you how new I am, I thought == meant not =. Thank you for helping me out.
