declaring a member function as const is a promise not to modify the object of which the function is a member; static data members must be defined (exactly once) outside the class body; 5. Static in C A static variable inside a function keeps its value between invocations. eg: void foo(...

成员函数(member function)是定义为类的一部分的函数,有时也被称为方法(method)。 endl是一个被称为操作符(manipulator)的特殊值。写入endl的效果是结束当前行,并将设备关联的缓冲区(buffer)中的内容刷到设备中。缓冲刷新操作可以保证到目前为止程序所产生的所有输出都会真正写入输出流中,而不是仅仅停留在内存中等待...
