※ 綜合應用：一個很簡單的剪刀石頭布遊戲

    string hand[3]  = {"剪刀","石頭","布"};

    for (int i=1;i>0;i++)

    {

        int A = (i%3) + 1;

        int B;

        string s1 = "電腦出";

        string s2 = "，請問您要出？(按1出剪刀，按2出石頭，按3出布，按其他離開遊戲)";

        cout<<s1+hand[A-1]+s2<<endl;

        cin>>B;

        if (A==1)

        {

            if (B==1){cout<<"雙方平手！"<<endl;}

            else if (B==2){cout<<"你贏了！"<<endl;}

            else if (B==3){cout<<"你輸了！"<<endl;}

            else {break;}

        }

        else if (A==2)

        {

            if (B==1){cout<<"你輸了！"<<endl;}

            else if (B==2){cout<<"雙方平手！"<<endl;}

            else if (B==3){cout<<"你贏了！"<<endl;}

            else {break;}

        }

        else if (A==3)

        {

            if (B==1){cout<<"你贏了！"<<endl;}

            else if (B==2){cout<<"你贏了！"<<endl;}

            else if (B==3){cout<<"雙方平手！"<<endl;}

            else {break;}

        }     

    }
