表达式 或花括号初始化器列表(C++11 起)(如果存在)被称为 return 语句的操作数。 在对函数调用结果的复制初始化和表达式 结尾处对所有临时量的销毁之间有一个序列点。 (C++11 前) 对函数调用结果的复制初始化按顺序早于在表达式 结尾处对所有临时量的销毁,后者按顺序早于 该 return...

return-type operator#(parameter-list) { ... } 关键字operator 用于重载函数.在上面语法中用特殊符(#)描述特征的操作将被重载.假如在一个类中,类名应当被指定.对于一元的操作,parameter-list应当为空, 对于二元的操作,在operator右边的parameter-list应当包含操作数 (在operand 左边的被当作this通过). ...

编译出错:error C2597: illegal reference to data member ‘Point::m_x’ in a static member function 因为静态成员函数属于整个类,在类实例化对象之前就已经分配空间了,而类的非静态成员必须在类实例化对象后才有内存空间,所以这个调用就出错了,就好比没有声明一个变量却提前使用它一样。
