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.

Question

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 <iostream>

#include <fstream>

#include <string>

#include <iomanip>

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;

}
