Inheritance(继承):表示 is-a Base Derived 内存上,就是子类「包了」一个父类,父类的析构函数要加上 virtual 关键字 继承与多态: 数据的继承是直接 copy 一份下来,函数的继承是继承了调用权,调用权也分三种: non-virtual: 不希望被 overriding virtual:希望被,而且自己有定义 pure virtual:希望被,但是自己...
(1)纯虚函数 virtual,纯虚函数一定要重新定义。(2)Inheritance + composition下的构造和析构 顺序。(3)delegation + Inheritance,功能最强大的一种。 版权声明:本文为surserrr原创文章,遵循 CC 4.0 BY-SA 版权协议,转载请附上原文出处链接和本声明。 本文链接:https://blog.csdn.net/surserrr/article/...

虚函数(virtual function)、运算符重载(operator overloading)、多重继承(multiple inheritance)、模板(template)、异常(exception)、RTTI、名字空间(name space)逐渐被加入标准。1998年国际标准组织(ISO)颁布了C++程序设计语言的国际标准ISO/IEC 14882-1998。C++是具有国际标准的编程语言,通常称作 ANSI/ISO C++。1998年...
Protected inheritance Public members and Protected members of base class 在子类中都变成protected members 只能在子类中访问到 Private members of base class 无法在子类中访问 Private inheritance 私有继承后子类就无法再被继承 Public members and Protected members of base class 在子类中都变成Private members...
Inheritance by Example Inheritance in C++ is accomplished using the : operator. Continuing with the Number and ImaginaryNumber example used above, consider the following code sample. Run this code class Number { public: Number() = default; Number( Number const& ) = default; virtual ~Number(...
由于存在对象切割的风险, 不要为任何有可能有派生类的对象提供赋值操作或者拷贝 / 移动构造函数 (当然也不要继承有这样的成员函数的类). 如果你的基类需要可复制属性, 请提供一个public virtual Clone()和一个protected的拷贝构造函数以供派生类实现.
For every virtual function, there is thefinal overrider, which is executed when a virtual function call is made. A virtual member functionvfof a base classBaseis the final overrider unless the derived class declares or inherits (through multiple inheritance) another function that overridesvf. ...
