Classes can contain static member data and member functions. When a data member is declared asstatic, only one copy of the data is maintained for all objects of the class. (For more information, seeStatic Member Functions.) Static data members are not part of objects of a given class type...
int X::si = 77; // Initialize static data member int main() { X xobj; xobj.set_i(11); xobj.print_i(); // static data members and functions belong to the class and // can be accessed without using an object of class X X::print_si(); X::set_si(22); X::print_si(); ...
classMyClass{public:intnon_static_member;// 非静态数据成员}; 静态数据成员(static data members): 静态数据成员是类定义中使用static关键字声明的数据成员。与非静态数据成员不同,静态数据成员在整个程序运行期间共享同一块内存空间,而不是为每个对象分配单独的内存。所有类的对象都共享相同的静态数据成员。静态数...
You can only have one definition of a static member in a program. Unnamed classes, classes contained within unnamed classes, and local classes cannot have static data members. Static data members and their initializers can access other static private and protected members of their class. The follo...
Because a static member is not part of any object, static member functions may not be declared as const . After all, declaring a member function as const is a promise not to modify the object of which the function is a member. Finally, static member functions may also not be declared as...
The data members or member functions of an object are all public. Any other part of the code can modify or delete them. There are two ways to add public data member and member function in an object. The first way is to create it in the constructor function. function foo() { // insi...

Both member methods and fields (variables) can be declared static. The most common example of a static member is Java's main() method. The main() method is declared as static because it must be called before any objects exist. Java Static Data Members or Fields...
Second, static member functions can directly access other static members (variables or functions), but not non-static members. This is because non-static members must belong to a class object, and static member functions have no class object to work with! Static members defined outside the clas...
