Question

Hi, I need to write a C++ program but I cannot figure out how to doit. Please write the entire program. Here is the problem:
Write a program that reads a student's name together with his orher test scores. The program shouuld then computer the average testscore for each student and assign the appropriate grade. The gradescale is as follows: A = 90-100 B = 80-89 C = 70-79 D=60-69 F =0-59 Your program must use the following functions:
a. A void function, calculateAverage, to determine the average ofthe five test scores for each student. Use a loop to read andsum the five test scores. (This function does not output theaverage test score. That task must be done in the functionmain.)
b. A value returning function, calculateGrade, to determine andreturn each student's grade. (This function does not output thegrade. That task must be done in the function main. )
Test your program on the following data. Read the data from a fileand send the output to a file. Do not use any global variable. Usethe appropriate parameters to pass values in and out offunctions.
