Help with virtual char getting 2 errors!

Ok I have created a basic menu system very minimal so I can figure out this virtual char thing. Ok here is my error message.

.\menu.cpp(22) : error C2679: binary '>>' : no operator found which takes a right-hand operand of type 'overloaded-function' (or there is no acceptable conversion)
