In Programming Exercise 13 (Chapter 8), you are asked to write a program to calculate students’ average test scores and their grades. Improve this programming exercise by adding a function to sort students’ names so that students’ data is output into ascending order according to their name.   The code is below, is there a way to implement a sort function perhaps? Right now it just outputs as shown in the picture attached.        #include  #include  #include  #include  using namespace std; void getData(ifstream& inf, string n[], double tstData[][6], int count); void calculateAverage(double tstData[][6], int count); void calculateGrade(double tstData[][6], char gr[], int count); void print(string n[], double tstData[][6], char gr[], int count);    int main() {   string names[10];     double testData[10][6];     char grade[10];     ifstream inFile;     inFile.open("data.txt");     if (!inFile)     {         cout << "Cannot open the input file: ch8_Ex13Data.txt." << endl;         cout << "Program terminates!" << endl;         return 1;     }     cout << fixed << showpoint << setprecision(2);     getData(inFile, names, testData, 10);     calculateAverage(testData, 10);     calculateGrade(testData, grade, 10);     print(names, testData, grade, 10);     inFile.close();   return 0; } void getData(ifstream& inf, string n[], double tstData[][6], int count) {     for (int i = 0; i < count; i++)     {         inf >> n[i];                  for (int j = 0; j < 5; j++)             inf >> tstData[i][j];         tstData[i][5] = 0.0;     } } void calculateAverage(double tstData[][6], int count) {      double sum;     for (int i = 0; i < count; i++)     {         sum = 0.0;         for (int j = 0; j < 5; j++)             sum = sum + tstData[i][j];         tstData[i][5] = sum / 5;     } } void calculateGrade(double tstData[][6], char gr[], int count) {     for (int i = 0; i < count; i++)         if (tstData[i][5] >= 90)             gr[i] = 'A';         else if (tstData[i][5] >= 80)             gr[i] = 'B';         else if (tstData[i][5] >= 70)             gr[i] = 'C';         else if (tstData[i][5] >= 60)             gr[i] = 'D';         else              gr[i] = 'F'; } void print(string n[], double tstData[][6], char gr[], int count) {     double sum = 0.0;     cout << left << setw(10) << "Name"          << right << setw(8) << "Test 1"          << setw(8) << "Test 2"          << setw(8) << "Test 3"          << setw(8) << "Test 4"          << setw(8) << "Test 5"          << setw(10) << "Average"          << setw(8) << "Grade" << endl;     for (int i = 0; i < count; i++)     {         cout << left << setw(10) << n[i];         cout << right;         for (int j = 0; j < 5; j++)             cout << setw(8) << tstData[i][j];         cout << setw(10) << tstData[i][5]              << setw(6) << gr[i] << endl;         sum = sum + tstData[i][5];     }     cout << endl << endl;     cout << "Class average: " << sum / count << endl;

The code is below, is there a way to implement a sort function perhaps? Right now it just outputs as shown in the picture attached.
