In C++, a static member is a member of a class that belongs to the class itself rather than to any instance of the class. It is shared by all instances of the class and can be accessed without creating any instance of the class. Static data members are declared using the keyword 'static' and must be defined outside the class declaration. Example: class MyClass { public: static int myStaticVar; }; int MyClass::myStaticVar = 0; // defining the static member outside the class int main() { MyClass obj1; MyClass obj2; MyClass::myStaticVar = 5; // accessing static member without creating object obj1.myStaticVar = 3; // this will also change the static variable for obj2 cout << obj1.myStaticVar << endl; // output: 3 cout << obj2.myStaticVar << endl; // output: 3 (since the static member is shared) } Static member functions are also shared by all instances of the c...
This blog is about providing theory as well as simple executable codes of different programming languages such as java, C, C++, and web programming, etc. This blog will be helpful to the IT students to learn about programming.
