     public:
       void setInt(int n)
       {
         i = n;
       }
       int getInt()
       {
         return i;
       }
   };
   int myclass::i; // Definition of myclass::i. i is still private to myclass.
   int main()
   {
     myclass object1, object2;
     object1.setInt(10);
     cout << "object1.i: " << object1.getInt() << '\n'; // displays 10
     cout << "object2.i: " << object2.getInt() << '\n'; // also displays 10
