Problem #1 (50 points): calculate average test score and letter grade

Write a program that randomly generates 20 test scores, between 50 to 100, and store them into an int array.

Include two overloaded functions with the following headers and requirements:

Headers:

double sum(const double TestScores[], int ArraySize, int& IndexHighestScore, int& IndexLowestScore)

int sum(const int TestScores[], int ArraySize, int& IndexHighestScore, int& IndexLowestScore)

Requirements:

i.Therefore, only 18 scores are to be sum and be used in finding the average score.

ii.These functions will retain of the indices (pass by reference) of the highest and lowest scores in the array.

Include two overloaded functions that return a letter grade of a score with the following headers and requirements:

Headers:

char LetterGrade( int testScore)

char LetterGrade( double testScore)

Requirements:

Determine and return the letter grade base on the test score (pass by value) as follow:

testScore >= 90, LetterGrade is A

testScore >= 80 and

testScore >= 70 and

testScore >= 60 and

testScore

Test the functions from the main() and display the exact output as follow:

Grading is as follow:

No submission or unable to compile. 50 points

Logic (occur when a program does not perform the way it was intended) errors. 5 points each

Runtime (causing the program to terminate unexpectedly) errors. 10 points each

Other errors for not follow directions 1 to -5 points each depend on its severity
