Question

This new version of the program needs to read an input file that contains twenty students each with five test grades. Each students test scores must be averaged and assigned a letter grade. This information will be used to create a Computer Science Grade Report to an output file in a tabular form with title and headings. After the students, tests, test average and grade are listed then display each test average and overall test average. Then display the highest test grade and Student with highest test average.

Explanation / Answer

#include <iostream>

#include <fstream>

#include <iomanip>

#include <string>

using namespace std;

int main()

{

//Declare variables;

double testScore;

double sum = 0;

string firstName;   

string lastName;

double scores[5] = {0};

int count = 0;

double highestGrade = 0;

string topperFirstName;

string topperLastName;

ifstream inFile; //input file stream variable

ofstream outFile; //output file stream variable

inFile.open("test.txt");

outFile.open("testavg.out");   

outFile << fixed << showpoint;

outFile << setprecision(2);   

cout << "Processing data" << endl;

while(!inFile.eof())

{

sum = 0;

inFile >> firstName >> lastName;

outFile << "Student name: " << firstName

<< " " << lastName << endl;

outFile << "Test scores: ";

for(int i=0;i<5;i++)

{

inFile >> testScore; //Read the first test score

outFile << setw(6) << testScore; //Output the test score

sum = sum + testScore; //Update sum

scores[i] = scores[i] + testScore;//Update sum of each test

}

outFile << endl;

double avg = sum / 5.0;

outFile << "Average test score: " << setw(6)

<< avg << endl << endl;

if(avg > highestGrade) //updating highest grade

{

highestGrade = avg;

topperFirstName = firstName;

topperLastName = lastName;

}

  

count++; //increase number of observations by 1

}   

sum = 0;

  

outFile << "Test averages: " ;

for(int i=0;i<5;i++)

{

outFile << setw(6) << scores[i]/count; //Output the test average

sum = sum + scores[i]/count;

}

outFile << endl;

  

outFile << "Overall test averages: " << setw(6)

<< sum/5.0 << endl ;

outFile << "Highest test grade: " << setw(6)

<< highestGrade << endl ;

outFile << "Student with highest grade: " << topperFirstName

<< " " << topperLastName << endl;

inFile.close();

outFile.close();

char holdscr; // This character and section is to hold screen open

cout << " Press a character and Enter to exit program. ";

cin >> holdscr;

return 0;

}
