    cout<<"press 1 to go to class 9th blue"<<endl;

    cout<<"press 2 to get into class 9th pink"<<endl;

    int a,c,e,d;

    cin>>a;

    switch (a){

case 1:{

    cout<<"you entered in 9th blue class"<<endl;

  int b[2][2]{

        {

            11,30

        },

        {

           85,97

        }

    };

    cout<<"enter the roll no of students there are only 2 of them"<<endl;

    cin>>c;

    if(c==1){

        cout<<b[0][0]<<" "<<b[0][1]<<endl;

    }else if(c==2){

    cout<<b[1][0]<<" "<<b[1][1]<<endl;

    }break;}

  case 2:{

    int d;

        cout<<"you entered in 9th pink class"<<endl;

    cout<<"enter the roll no of students there are only 2 of them"<<endl;

    cin>>d;

    if(d==1){

        cout<<e[0][0]<<" "<<e[0][1]<<endl;
