• A default constructor which will initialize all data members with values 2.5 and 2.5 for base and height.

I'm using Dev-C++ 4.9.9.2 to compile a program I wrote about five years ago.
I recall that it compiled without errors when I first wrote it.
I had to change a few things, because I guess the code was getting a little old. Anyway, I got rid of all of the errors except this WinMain@16 thing. I've...
