move constructor 的语法:&&,内部原理:打断传入对象的引用的外部指针,自己指向它,实际是完成了一次浅拷贝 测试函数:感觉有文章讲得更好,就是左值右值,临时对象那一套 附 Component 和 Inheritance 的构造和析构顺序 // comp-base-derived class Comp { public: Comp() { std::cout << "Comp construct()" <...

methods, including destructors but not constructors, virtual. Constructors cannot and need not be virtual because you always specify the exact class being constructed when creating an object. 当然,将赋值运算符设置为 virtual 意义并不大,因为父类引用或者指针只能管到自己本身的数据成员。
