Project objective: write a program that takes a list of final scores for a class and determines: 1) the mean (Greek letter mu)2) the standard deviation (Greek letter sigma). and 3] the number of grades in each category (A. A-, B+, B-, C+. C, C-, D+, D an Use the following formulas for the standard deviation and mean, respectively. (zi-A)2, where = N .ri 2- 2- Prompt the user for the name of a file containing the final scores, up to 100 scores, such as (without the commas): 100, 94, 59,83,57,11,92,76,37,89, 74, 59,65,79, 49,89,89,75, 64, 82, 15, 74, 82, 68, 92,61,33,95, 91,82,89,64, 43, 93, 86, 65, 72, 40, 42,90, 81,62,90,89,35,81,48,33,94,81,76,86,67, 70, 100, 80, 83, 78,96, 58 Note: m=71.47 s= 20.98 Determine the maximum score, the minimum score, the range of scores (maximum - minimum) and a table with column headings: Grade Number of scores using the following scoring (where m is the mean, s is the standard deviation, and x is an individual score): Place the output in a file, in an orderly format, and inform the user of the name of the file before exiting,

float deviation(float sum, float mean, float N);
float mean(float vector[], int size);
float sum(float vector[], int size);

int main()

   ifstream inFile;
   float N;
   int size = 0;
   const int Numlist = 1000;
   float totalSum;
   float avg = 0.0;
   int max = 100;
   int min = 11;
   double m = 71.47;
   double s = 20.98;

   double List[Numlist];

   inFile.open("input.txt");
   if (inFile.fail())
   {
       cout << "Error: could not open input.txt" << endl;
       exit(EXIT_FAILURE);
   }

   for (int count = 0; count < Numlist; ++count){
       inFile >> List[count];
       if (!inFile)break;
   }

   float standard_deviation[100];
   inFile >> N;
   while ((!inFile.eof()) && (size<Numlist))
   {
       standard_deviation[size] = N;
       size++;
       inFile >> N;
   }

   totalSum = sum(standard_deviation, size);
   avg = mean(standard_deviation, size);

   cout << "Standard Deviation = " << deviation(totalSum, avg, size) << endl;
   cout << "Mean = " << avg << endl;
   cout << "Maximum Score = " << max << endl;
   cout << "Minimum Score = " << min << endl;
   cout << "Range = " << (max - min) << endl;
   cout << "Grade" << " " << "Number of Scores" << " " << endl;

   system("pause");
   return 0;

//Sum Function

float sum(float vector[], int size)
{
   float theSum;
   theSum = 0.0;
   for (int N = 0; N < size; N++)

   return theSum;

//Mean Function

float mean(float vector[], int size)
{
   float sum = 0.0, mean = 0.0;

   for (int i = 0; i < size; i++)

   if (size == 0)

//Deviation function

float deviation(float sum, float mean, float N)
{
   double S;
   double U;

   U = (pow(sum - mean, 2));
   S = (sqrt(U / N));

   return S;
