C++

Because in the C language, you cannot put all the code in a. c file, so this. c file will be large, and the code will be cumbersome to maintain.So I found some examples of C language multi-file programming on the Internet, and recorded my learning

1. Inheritance and overwriteSubclasses inherit the parent class, and subclasses can override functions of the base class. Of course, it is no problem to create an object directly from a subclass, with a pointer to the child class. The function that

Rand_max is a character constant defined by the macro in Stdlib.h in C: #define Rand_max ox7fff with a value of 32767, and a maximum of 2147483647 is usually used when generating random decimals. Given C + + Example://Run in VC6.0 through #include

These two days re-learn the data structure, the reference book uses C described, because previously used Java,C has been unfamiliar a lot, the pointer that piece is not solid,Deeply feel the collision from object-oriented and process-oriented,
