Why do you ignore compiler errors? Please read error messages that the compiler issue.
All it said was that you cant have a double and an int in line 48. I don't understand how arrays work so I do not know how to fix it.
i think you meant points_possible_array[quiz_number] = points_possible
yes. that is exactly my problem and i do not know how to fix it. and I would really like some help.
I think what DTSCode means is that at line 48,
|
points_possible[quiz_number] = points_possible;

the variable points_possible[quiz_number] should really be points_possible_array[quiz_number]
