I am having a problem figuring out how to calculate the class average and output it in the program I have written below. Any help on how to do this is appreciated.

#include #include #include #include

using namespace std;

const int MAX = 50; // a function called GetData to read and store data into two arrays, void GetData(ifstream& infile, string name[], int scores[][5], int& n) { n = 0; int i = 0; int j = 0; while (!infile.eof()) { infile >> name[i]; for (int j = 0; j<5; j++) infile >> scores[i][j]; i++; } n = i; }

char determineGrade(double avg) { if (avg >= 90 && avg <= 100) return 'A'; else if (avg >= 80 && avg <= 89) return 'B'; if (avg >= 70 && avg <= 79) return 'C'; if (avg >= 60 && avg <= 69) return 'D'; if (avg >= 50 && avg <= 59) return 'F'; }

// a function called Average that is used to calculate the average test score and grade, void Average(int a[][5], char grade[], double avg[], int no_of_students) { for (int i = 0; i (5); grade[i] = determineGrade(avg[i]); } }

// function called PrintResults to output the results. void PrintResults(string name[], double avg[], int scores[][5], char grade[], int n) { for (int i = 0; i

int main() { // a one-dimensional array to store the students names, string name[MAX]; // a (parallel) two-dimensional array to store the test scores, int scores[MAX][5]; // a parallel one-dimensional array to store grades. char grade[MAX]; int no_of_students; double avg[MAX];

ifstream infile("Arrays.txt");

if (!infile) { cout << "unable to open file.so exiting from program" << endl; return 0; }

GetData(infile, name, scores, no_of_students); infile.close(); Average(scores, grade, avg, no_of_students); PrintResults(name, avg, scores, grade, no_of_students);

return 0; }

the arrays.txt file is the following information
