正統C++的member function寫法應該是class definition寫在header file,class implementation寫在.cpp,這種寫法的優點是,由SA/Architect定出interface後,將header file交給programmer寫程式,且註解都寫在header file中。 但這種寫法的缺點是,每個class都要兩個檔案,一個是.h,一個是.cpp,日後一個專案檔案會很多,造成管理...
从上表可以看出有两种方法重载一些class操作符:作为成员函数(member function)或作为全域函数(global function)。它们的用法没有区别,但是我要提醒你,如果不是class的成员函数,则不能访问该class的private 或 protected 成员,除非这个全域函数是该class的 friend 。所以,用成员函数的方式会更好一些。 8. 关键字this: ...

CS0267:“partial”修饰符只能出现在紧靠“class”、“record”、“struct”、“interface”或方法或属性返回类型前面的位置。 CS0282:分部类或结构“type”的多个声明中的字段之间没有定义的排序。要指定排序,所有实例字段必须位于同一声明中。 CS0501:“member function”必须声明主体,因为它未标记为abstract、extern或...
The function validateFloats is not a member function, and I also don't declare it in the header file. I only use this function inside of the validateFloats.cpp file. Someone told me this may cause some problems. Is that true? c++ class member-functions Share Improve this que...
void say(); void say(); // ok class Test{ void say(); void say(); // error class member cannot be redeclared }; is this because class member function declaration allocates memory so that the compiler doesn't allow redeclaration? Thanks in advance. c++ Share Improve this question...

If you define your own seekoff() function, it should return EOF if the derived class does not support repositioning. If the class does support repositioning, seekoff() should return the new position of the affected pointer, or EOF if an error occurs. ...
