class DataStorage{
                        // 0 1 2 3 4        5 6 7 8
string Data[20][4]={{"Wee","50","1","First"},{"Wee","22","2","First"},
                        // 9 10 11 12       13 14 15 16
                    {"Jason","26","3","First"},{"Krappa","12","4","First"},
                        // 17 18 19 20      21 22 23 24
                    {" "," ","5","First"},{" "," ","6","Economy"},
                        //25 26 27 28       29 30 31 32
