Thread: errors with virtual functions

I am using the Dev C++. I have also provided the virtual functions implementations along with the child class definitions. I just removed them, when posting the code.

I'm not sure what the problem is but MinGW GCC 4.5 can compile your code as is. To get the same amazing result, you could just upgrade your compiler (which means throwing Dev-C++ away probably) and try this orthis .
