Write C + + code will often use the standard C of things, both mixed up with the use of the inevitable type mismatch, need to convert, often used sprintf to convert char* type to String type Later encountered string type conversion to char * type,

The previous article has analyzed the basic structure, C + + simple objects, plus the general inheritance of the various situations, this article will mainly in the virtual inheritance, the C + + object memory is how to allocate. Virtual Inheritance

This small tutorial, recommended to use the computer to see, open your IDE, directly copy and paste the code class and the structure of the different (P47) C + + More before we learn to add a class (Class) type, that is, we now want to learn the
