Question

Given a basic template to calculate a course average you must revise the program to do the following.

1.Take in the students name

2.Make the program match the items and percentages listed on our class syllabus

3.Use a random number generator to determine a grade for each component of the syllabus (i.e Labs & Quizzes: 80%) & use a seed of 12

4.Output the final average as a number and letter grade

// Example program
#include <iostream>
#include <string>
#include <cstdlib>   
#include <ctime>

int main()
{
srand(time(0))
//// Variables

const double HOMEWORK_MAX = 100.0;
const double QUIZ_MAX = 100.0;
const double EXAM1_MAX = 100.0;
const double EXAM2_MAX = 100.0;
const double PROJECT_MAX = 100.0;
const double INCLASS_MAX = 100.0;
const double FINAL_MAX = 100.0;
const double HOMEWORK_WEIGHT = 0.15; // 15%
const double EXAM1_WEIGHT = 0.30;
const double EXAM2_WEIGHT = 0.30;
const double PROJECT_WEIGHT = 0.15;
const double INCLASS_WEIGHT = 0.15;
const double QUIZ_WEIGHT = 0.15;
const double FINAL_WEIGHT = 0.15;
  
double homeworkScore = 0.0;
double midtermScore = 0.0;   
double quizScore = 0.0;
double projectScore = 0.0;
double inclassScore = 0.0;
double finalScore = 0.0;
double coursePercentage = 0.0;
