What are top-down and bottom-up approach in C++ design? How do you
usually use them?

 

[guyarad]

Top-Down or Bottom-Up design are not related specifically to C++.
C++ is a programming language, not design lanuage.

You can implement design in c++, pascal, java etc.

anyway, you sould try google before asking such questions here.

Here is a fairly good description.

I do it both ways, I couldn't really explain why or how I choose one or the
other. If it is something where I have absolutely no prior knowledge, I
think it is necessary to do a least a bit of top down thinking first.
