Class names that start with C

Question

The MFC has all class names that start with C. For example, CFile and CGdiObject. Has anyone seen it used elsewhere? Is there an official naming convention guide from Mic

Answer 1

That was a old C++ coding style, and MFC was probably one of the last things to use it.

It was usually just a convention of C++ (and maybe a few other languages), and hence it started falling out of favor as the languages became more interoperable, through COM and then .NET.

You still see it's cousin, the "I" prefix for interfaces, pretty often. I've always found it interesting that "I" survived when "C" died, but that was probably because interfaces were used so heavily in COM interoperability.
