so i can use it in some static methods

class CMyClass {
private:
   static int myMagicNumber;   // defined static member variable here
public:
   static void magic() {       // defined a static method here
      std::cout << "My magic number is: " << myMagicNumber << std::endl;
   }
};

// initialize the static member variable in one of your cpp files like this:
CMyClass::myMagicNumber = 111;

int main() {
   // call your static method like this:
   CMyClass::magic(); // prints "My magic number is: 111"
}
