Question

Create a class named Game using the following UML class diagram.

GAME

-gameName : string

+Game()

+setGameName(in name : string) : void

+getGameName() : string

+displayMessage() : void

This class has 2 member variables namely playerName and playerScore. The class contain following member functions: Constructor, set function, get functions, display function.

Code write in 3 files: Game.h header file, funtion.cpp file and main.cpp file.

The output should be: Player John has scored 50 points.

Answer 1

//Game.h
#ifndef GAME_H
#define GAME_H
#include<iostream>
#include<string>
using namespace std;
class Game
{
private:
   //private data members
   string playerName;
   int playerScore;
public:
   //public function declarations
   Game();
   Game(string,int);
   void setGameName(string);
   string getGameName();

   void setGameScore(int);
   int getGameScore();

   void displayMessage();
};
#endif GAME_H

//Game.cpp
//include header files
#include<iostream>
#include<string>
#include "Game.h"
using namespace std;
Game::Game()
{
   playerName="";
   playerScore=0;
}
Game::Game(string pName,int pScore)
{
   playerName=pName;
   playerScore=pScore;
}
void Game::setGameName(string pName)
{
   playerName=pName;
}
string Game::getGameName()
{
   return playerName;
}
void Game::setGameScore(int pScore)
{
   playerScore=pScore;
}
int Game::getGameScore()
{
   return playerScore;
}
void Game::displayMessage()
{
   cout<<"Player "
       <<playerName
       <<" has scored "
       <<playerScore<<" points."
       <<endl;
}

/*
Cpp file that tests Game class
and print the message output on
console.
*/
//main.cpp
//include header files
#include<iostream>
#include"Game.h"
using namespace std;
//start of main function
int main()
{
   //Declare Game class object
   Game game;
   //Calling set methods
   //To set name
   game.setGameName("John");
   //To set score value
   game.setGameScore(50);
   //calling displayMessage method
   game.displayMessage();
   //pause program output on console
   system("pause");
   return 0;
