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. Write the following methods in the program: calcAverage: This method should accept five test scores as arguments and return the average of the scores. determineGrade: This method should accept a test score as an argument and return a letter grade for the score, based on the following grading scale:

See comment for complete question

#include <iostream>

using namespace std;

double calc_Average(double sc1, double sc2, double sc3, double sc4, double sc5){

   return (sc1 + sc2 + sc3 + sc4 + sc5)/5;

}

char determine_Grade(double score){

   char grade;

   if(score >= 90 && score <=100){

       grade = 'A';}

   else if(score >= 80 && score <90){

       grade = 'B';}

   else if(score >= 70 && score <80){

       grade = 'C';}

   else if(score >= 60 && score <70){

       grade = 'D';}

   else if(score <60){

       grade = 'F';}

   return grade;

}

int main(){

   double sc1,sc2, sc3, sc4, sc5;

   cout<<"Enter 5 scores: ";

   cin>>sc1>>sc2>>sc3>>sc4>>sc5;

   cout<<"Score: "<<sc1<<" Grade: "<<determine_Grade(sc1)<<endl;

   cout<<"Score: "<<sc2<<" Grade: "<<determine_Grade(sc2)<<endl;

   cout<<"Score: "<<sc3<<" Grade: "<<determine_Grade(sc3)<<endl;

   cout<<"Score: "<<sc4<<" Grade: "<<determine_Grade(sc4)<<endl;

   cout<<"Score: "<<sc5<<" Grade: "<<determine_Grade(sc5)<<endl;

   double Ave = calc_Average(sc1,sc2,sc3,sc4,sc5);

   cout<<"Average: "<<Ave<<" Grade: "<<determine_Grade(Ave)<<endl;

   return 0;

}

Explanation:

The program was written in C++. Because of the length of the explanation, I've added the explanation as an attachment where I used comments to explain the lines of the code.
