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(...

重定向:prog < infile >outfile:从一个名为infile的文件中读取输入,输出到outfile。 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...
