Then the program should take 10 inputs one by one,

• After taking 10 inputs, you should display no. of A grades.

• If A grades are less than or equal to 7, you should display a message "Your class is Good!".
• If A grades are greater than or equal to 8, you should display a message "Your class is Brilliant!".
• The user should enter either A or B. If user has entered other than A or B, e.g. C,D,E etc. Your program should display a message like;
