I am getting compiler output that makes me think I have some sort of syntax error like a missing ';' or misaligned (). But I've checked my code thoroughly and can't find anything wrong. What else could cause this kind of error? I included the compiler output along with my .h and .cpp file for the class that won't compile. The other header files I #include shouldn't be causing the problem as they've already been thoroughly tested.
Compiler output:
