类的编写与应用，构造与析构函数，函数的重载，类的继承，函数覆盖，基类与派生类的构造函数、析构函数先后调用顺序，如何在派生类构造函数中向基类的构造函数传递参数，this成员变量，类型转换的内幕，虚拟函数与多态性,引用和指针变量的区别与共同处。VC工程的编译原理与过程，将工程中不同的类拆分到不同的文件中，每一个类由一个.h和.cpp文件共同完成，头文件重复定义问题的解决，培养了学员良好的编程习惯，也为以后分析MFC AppWizard生成的工程奠定了良好基础。-Overload class preparation and application structure and destructor function, class inheritance, function coverage, the base class constructor and derived class destructor has the calling sequence, how the derived class to the base class constructor constructor passing parameters, this member variable, type conversion insider, virtual functions and polymorphism, which differs in common references and pointer variables. VC compiler theory and process engineering, the project in different classes split into separate files, each class completed by an .h and .cpp files, header files, duplicate solve the problem definition, cultivate students good programming habits, but also for later analysis MFC AppWizard-generated project has laid a good foundation.
