JointThe difference between union and structure is that the structure applies a memory space for each field, and the union just applies a memory space and all the fields are saved in this space, the size of the space is determined by the longest in

1. The core idea of object-oriented program design is data abstraction, dynamic binding and inheritance.Inheritance: roots are called base classes, and inherited classes are called derived classes. A derived class must explicitly indicate which base

In C or C + +, we've learned how to implement a static order table, so why introduce a template class to implement a static order table? First, let's see, before we introduce a template, we define a static sequential table in C + +:typedef int

Polymorphism and virtual function of http://www.cnblogs.com/CaiNiaoZJ/archive/2011/08/11/2134673.htmlC++The polymorphism in object-oriented programming is to send the same message to different objects, and different objects produce different

In the analysis of the Code of the pointer, the mind must have a memory allocation diagram, used to analyze the various variables stored.1. Use variable A to give the following definitionA) An integer number (an integer)b) A pointer to the integer

A total of eight chapters content. The first chapter. The pointer's conceptual pointer is a special variable that stores values that are interpreted as an address in memory. To make sense of a pointer, you need to be aware of the four aspects of the

Intelligent pointer implementation and intelligent pointer implementation When I saw the iterator, I thought about how to summarize the knowledge of smart pointers. I have implemented three smart pointers: auto_ptr, scoped_ptr, and shared_ptr. They
