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

What I have seen some people like you do is write everything in the headers. That gives your desired property of only having to write the method profiles once.

Personally I think there are very good reasons why it is better to separate declaration and definition, but if this distresses you there is a way to do what you want.
