Assignment task: Test Average and Grade, Programming Exercise #7 on p 329 (modified). This is an algorithm in pseudocode. Allow the user to enter any 2 integer test scores in main(). Send those 2 scores to a function that will compute and return the average back to main(). Send the average to a function that will compute and return the course letter grade (A,B,C,F) back to main() Main will print the average and the letter grade. 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.
