Can I write C++ code without headers (repetitive function declarations)?

Question

Is there any way to not have to write function declarations twice (headers) and still retain the same scalability in compiling, clarity in debugging, and flexibility in desi

Answer 1

Learn to recognize that header files are a good thing. They separate how codes appears to another user from the implementation of how it actually performs its operations.

When I use someone's code I do now want to have to wade through all of the implementation to see what the methods are on a class. I care about what the code does, not how it does it.
