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
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(...
The name of any static data member and static member function must be different from the name of the containing class. Explanation Static members of a class are not associated with the objects of the class: they are independent variables with staticor thread(since C++11)storage durationor regula...
You must take note not to use static member function in the same manner as non-static member function, as non-static member function can access all of the above including the static data member. A non-static member function can be declared as virtual but care must be taken not to declare...
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(); ...
Member variables aren’t the only type of member that can be made static. Member functions can be made static as well. Here is the above example with a static member function accessor: #include <iostream> class Something { private: static inline int s_value { 1 }; public: static int ge...
int C::i = C::f(); // initialize with static member function int C::j = C::i; // initialize with another static data member int C::k = c.f(); // initialize with member function from an object int C::l = c.j; // initialize with data member from an object ...

Static member variables Before we go into the static keyword as applied to member variables, first consider the following class: #include<iostream>structSomething{intvalue{1};};intmain(){Something first{};Something second{};first.value=2;std::cout<<first.value<<'\n';std::cout<<second.value...
