/* Your code goes here */

{

teamLions = 500;

teamDolphins = 500;

}

#include  //to use input output functions

using namespace std; //to identify objects like cin cout

class GamePoints {  //class GamePoints

   public: GamePoints(); // constructor of GamePoints class

   void Start() const;  //method of GamePoints class

   private: //declare data members of GamePoints class

   int teamDolphins; // integer type private member variable of GamePoints

   int teamLions; }; // integer type private member variable of GamePoints

   GamePoints::GamePoints()  //constructor

    { teamLions = (500), teamDolphins= (500); }   //assigns 500 to the data members of teamLions  and teamDolphins of GamePoints class

   void GamePoints::Start() const    { //method Start of classs GamePoints

       cout << "Game started: Dolphins " << teamDolphins << " - " << teamLions << " Lions" << endl; }  //displays the values of teamDolphins and teamLions i.e. 500 assigned by the constructor

       int main() //start of main() function

       { GamePoints myGame;  // creates an object of GamePoints class

       myGame.Start(); //calls Start method of GamePoints class using the object

       return 0; }

The output of the program is:

Game started: Dolphins 500 - 500 Lions
