Draw a flowchart that would provide a workable solution to the following problem.

A teacher would like a program to help calculate student grades and print a report. They would like the program to work in the follow manner:

1. All data entry, names and scores, will be done on the keyboard.

2. Have the user (the teacher, the person running the program) enter the name of the first student. The program should work for any number of students up to twenty. There needs to be some sort of end-of input check. You do not need to check for more than 20; there will never be more than 20 students in a class, but there could be less than 20.

3. If it is not the end of input, have the user enter three scores between 0 and 100 inclusive. It is not necessary to do error checking, you can assume that the user will enter scores in the correct range.

4. Calculate the average of the three scores.

5. Determine the letter grade based on

Average 90 or above = A

Average 80 up to but not including 90 = B

Average 70 up to but not including 80 = C

Average 60 up to but not including 70 = D

Average less than 60 = F

(Hint: Determining the letter grade is not a Process or Input operation. Think series of Decisions.)

6. Print the students name and letter grade.

7. At the end of the report print the total number of students in the class.
