因为对象需要创建才存在,而non- static member是和object绑定的。所以static member functions禁止访问non-static member (neither member variables nor member functions),当然也无法在函数内部使用this关键字。 Const member functions3 当一个类的对象被限定为const时,从类的外部访问其member data时仅能进行read-only,...
C++自学精简教程 目录(必读)static 静态成员类的静态成员 static member 变量全局只有一份副本,不会随着类对象的创建而产生新的副本。 在类的成员变量前面增加 static关键字,表示这个成员变量是类的静态成员变量…
f2=X::f1; //using f1 to initialize f2 16 int X::f3=X::f();//initialized using static function 17 int X::f4=x.f1; //intialized with object data member 18 int X::f5=x.f(); //initialized with function from object 19 int X::f6=x.f7;//initialized using non static member of...
就是因为static member data是属于类级成员数据,non static member data是属于对象级成员数据,而static member function是属于类级成员函数,non static member function是属于对象级成员函数。对于一个类级成员函数只能访问到类级成员数据。因为类级成员是共享的,而对象级成员是私有的,私有的数据只能是由私有函数来读取...
转自:C语言中的static变量和C++静态数据成员(static member)C语言中static的变量:1).static局部变量 a、静态局部变量在函数内定义,生存期为整个程序运行期间,但作用域与自动变量相同,只能在定义该变量的函数内使用。退出该函数后, 尽管该变量还继续存在,但不能使用它

They cannot access nonstatic class member data using the member-selection operators (. or –>). They cannot be declared as virtual. They cannot have the same name as a nonstatic function that has the same argument types. 备注 The left side of a member-selection operator (. or –>) that...
静态成员函数(static member functions)和非静态成员函数(non-static member functions)的核心差异包含以下逻辑推导:1. **调用方式差异**:静态函数属于类本身而非实例,因此可直接用类名调用(如`ClassName::Func()`),而非静态函数必须通过对象(如`obj.Func()`)。2. **数据访问权限制**:静态函数无法访问类的非...
memory about static data member and static member function,classc1{public: staticvoidaddCount();public: staticintnCount;};nCount,在c1所定义的对象之间共享,其位于程序的数据段(程序的一个globaldatasegment)。其不会随着对象数据的增加而增
