Write a program that asks the user to enter five test scores. The program should display a letter grade for each score and the average test score. Design the following functions in the program: • calcAverage – This function should accept five test scores as arguments and return the average of the scores. • determineGrade – This function should accept a test score as an argument and return a letter grade for the score (as a string), based on the following grading scale: Score Letter Grade 90-100 A. 80-89 B 70-79

You must have 2 functions: one computes the average and the other finds the letter grade.
The average function should return back a Real value and the letter grade function should return back a string. All input and output must occur in main().
Only find and display the letter grade for the average, not  each test score. 
Should be an algorithm done in pseudocode.
7. Test Average and Grade
Write a program that asks the user to enter five test scores. The program should display a letter grade for
each score and the average test score. Design the following functions in the program:
• calcAverage – This function should accept five test scores as arguments and return the average of
the scores.
· determineGrade – This function should accept a test score as an argument and return a letter grade
for the score (as a String), based on the following grading scale:
Score
Letter Grade
90-100
A
80-89
В
70-79
60-69
