主流编程语言的强制类型转换原理

如何用VS打包应用程序

C++实现CRC-8/MAXIM算法

1.派生类不继承基类的三种函数：构造函数、赋值运算符、析构函数。2.创建派生类先调用基类构造，再调用派生类构造由以上两点可知：1.如果基类使用系统默认构造函数，且派生类没有任何新数据成员，就可以不用定义派生类的构造函数；如果基类显示定义无参构造，无新数据成员的派生类依然可以不用显示定义构造函数；如果基类显示定义了带参构造，那么无新数据成员的派生类就要显式定义构造函数。Base::Base(int para){}Derive::Derive() : Base(100){};注意，派生类构造函数的

基类析构函数是否为虚影响派生类析构函数的调用class Base //基类{public: ~Base(); //此处将基类析构函数设置为常规析构};Base::~Base() //基类析构函数{ cout << "Base Destruct" << endl;}class Derive:public Base //派生类{public: ~Derive();};Derive::~Derive() //派生类析构函数{ cout &
