My program runs fine without my shortcut key input, but when I use my shortcut key input I get this error... its a multi project file so I am going to include, error is on line 58 in client.cpp, i'll post my code for the files down below. It does everything it is supposed to do I just would like advice on how to stop this weird const error. *NOTE I CANNOT CHANGE THE CLIENT PROGRAM I HAVE TO USE IT AS IS*
/*Client.cpp is set-up as a Fraction class implementation and test driver program - DO NOT CHANGE SOURCE CODE

I don't see anything about "shortcut keys" in your program.
However, it's important to make a member function const if you can (i.e., if it doesn't modify *this). All of your functions can be made const except for the ctors, getFraction and simplify.
