Write a letter Grade function that gets an average score as an argument and returns the letter grade. If the average score is 90 or more, return an A. 80 to 89 – return a B. 70 to 79 – return a C. 60 to 69 – return a D. If the average score is less than 60, return grade F. Write the main function to ask the user his/her name and the number of test scores he/she has. Then ask the user to input those test scores (using a loop only). Then find the average test score. Then call the letter Grade function to get the letter grade. Display the average score and the person’s letter grade.

Consider the following function main: int main() { int alpha[20]; int beta[20]; int matrix[10][4]; . . } a. write the definition of the function inputarray that prompts the user to input 20 numbers and stores the numbers into alpha. b. write the definition of the function doublearray that initializes the elements of beta to two times the corresponding elements in alpha. make sure that you prevent the function from modifying the elements of alpha. c. write the definition of the function copyalphabeta that stores alpha into the first five rows of matrix and beta into the last five rows of matrix. make sure that you prevent the function from modifying the elements of alpha and beta. d. write the definition of the function printarray that prints any onedimensional array of type int. print 15 elements per line. e. write a c11 program that tests the function main and the functions discussed in parts a through d. (add additional functions, such as printing a two-dimensional array, as needed.)
