1. 构造函数。 The base-class object is constructed first. 1. 首先构造基类对象。 The derived-class constructor should pass base-class information to a base-class constructor via a member initializer list. 2. 继承类

原创 默认构造函数
Default Constructor: C++ Compiler generates automatically if you don't define one. 以class Time为例 ： 系统自生成默认构造函数为： Time::Time() {} // implicit and does nothing 定义一个类变量时： Time curTime; // 类没有初始化 自定

原创 运算符重载与友元
Keep in mind that you must choose one or the other form when defining a given operator,but not both. 加法：operator+ 以class Time为例： T1 = T2 + T3; --> T1 = T2.operator+(T3); // member function --> T1
