1. In the future development of the program state
- With c ++ language to express constraints on the design, rather than using a comment or a document.
- Note that virtual destructor
- and many more
2. The non-leaf class is designed to abstract class
3. How to use c ++ and c mixed in the same program
- Ensure that a compatible obj file
- Name conversion
Because c no function overloading, so there is no name transformation, displays all need to tell c ++ compiler can not be converted to a function name in other languages,
Use extern indicating 'C'. Not only indicates the c language,
_Cplusplus only by macro defined in c ++ compiler
#ifdef _cplusplus
extern "C"{
#endif
void drawLine(int x1, int y1, int x2, int y2);
void twiddleBits(unsigned char bits);
void simulate(int iterations);
#ifdef _cplusplus
}
#endif
- Static initialization
If you have a static object c ++ program, it is recommended to use c ++ main function.
- Dynamic memory allocation
new delete 和 malloc free
- Compatibility Data Structure
