Hello everyone I post last night with this same code, and I got a lot of advice. But there are 3 more errors that persist after I changed the code a bit. Anyone know whats wrong?
Here are the errors:
1>------ Build started: Project: circle, Configuration: Debug Win32 ------
1>Compiling...
1>circle.cpp
1>c:\users\emcy\documents\visual studio 2008\projects\circle\circle\circle.cpp(39) : error C2664: 'diameter' : cannot convert parameter 1 from 'double (__cdecl *)(double,double,double,double)' to 'double'
1> Context does not allow for disambiguation of overloaded function
