void ShowCardP2(int, string [], string [], string [], string [], string []);
int Score(int ,int ,int [],int []);
int FinalScore (int,int);

    //loop for game
    do{
    int scP1=0,scP2=0; 

    for (int round=1;round<6;round++)
    {//loop for 5 round

        cout <<"\t***********";
        cout<<endl<<"\t  ROUND "<<round<<"\n";

    cout<<endl;

    cin.get();

    }//end loop for round


    //score total round
