Employee Dave created In Delegating Constructor. Employee Dave created 补充: 构造函数名=default:让编译器生成默认的某构造函数。 构造函数名=delete:让编译器禁止调用某构造函数。 八,参考阅读 《C++新经典》 《C++ Primer》 《C++ Primer Plus》 C++ Constructors: Types and Copy Constructors (programiz....

只在需要接管的时候才自定义operator=和copy constructor,如果编译器提供的默认版本工作的很好,不要去自找麻烦,自定义的版本勿忘拷贝每一个成分,如果要接管就要处理好。 组合优先于继承,继承是一种最强的类间关系 典型的适配器模式有类适配器和对象适配器,一般而言,建议用对象适配的方式,而非用基于继承的类适配方式...
