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
While MFC and lots of software written for Windows used the "C" convention for classes, you generally don't find the latter in software written for UNIX platforms. I think it was a habit very strongly encouraged by Visual C++. I remember that Visual C++ 6.0 would prefix a "C" to any classes that one created with the class wizard.
