Converting an Arabic Number to a Roman Numeral

[iamtheodork]

Hello C++ Gurus, I need your aid once again. So far I have the "Menu" setup and now I just need to run a separate class that I created called romanType. I have the "Convert Arabic to Roman Numeral" currently setup (I hope the algorithm is correct) and I'm having trouble linking the menuDriver.cpp and romanType.cpp. Here is my code for all the parts (romanType.cpp, menuDriver.cpp, and romanType.h).

What need help with is that 1) It doesn't compile and 2) Let's say it does compile, it will loop back to the menuDriver after I enter an Arabic Number.

Thank you!
