Problem Statement: Calculating No. of A Grades in Class You are required to write a program which should take input from user in the form of characters A or B. Based upon user’s input you should calculate no. of A grades. You should use while loop or do/while loop for taking input and if / else condition for making decisions.

Detailed Description:

The program should display like;

Please Enter Grade (‘A’ OR ‘B’ )

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 2, you should display a message “Your class is Poor!”.
• 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; 

     "Please Enter 'A' or 'B' grade only!"
