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() = default; virtual ...
break语句只能跳出本层循环,假如你要跳出一个三重嵌套的循环,你就要使用包含其它的逻辑或者用一个goto语句跳出这个嵌套循环. case 在switch里面用来检测匹配 . default,switch catch catch 语句通常通过throw语句捕获一个异常. 这一页... class class-name : inheritance-list { private-members-list; protected: pro...
