Question

Ok, this is c++, and it is an implementation of a class student in three files: main.cpp, student.h, and student.cpp

What I am stuck at:

In each score for each student, instead of printing just the average, I need to print their scores as well, and then the average.

Also, Mary was living in White Plains, but  Mary moves to Pleasantville. I would like to show both, that she lived there, and moved.

Thanks!!

Student s2(95791, "Mary", "Jones", "White Plains");

Student s3(98181, "Jessica", "Nascimento", "Stamford");

s1.addScore(65);

s1.addScore(87);

s1.addScore(75);

s2.addScore(90);

s2.addScore(80);

s2.addScore(85);

  

s3.addScore(100);

s3.addScore(100);

s3.addScore(100);

Explanation / Answer

I have changed the code according to your requirements. Now it's printing everything you wanted.

MAIN.CPP

#include <iostream>

#include <iomanip>

#include <string>

#include "student.h"

using namespace std;

int main()

{

Student s1(91313, "Joe", "Smith", "Rye");

Student s2(95791, "Mary", "Jones", "White Plains");

Student s3(98181, "Jessica", "Nascimento", "Stamford");

s1.addScore(65);

s1.addScore(87);

s1.addScore(75);

s2.addScore(90);

s2.addScore(80);

s2.addScore(85);

  

s3.addScore(100);

s3.addScore(100);

s3.addScore(100);

  

  

cout << " Student 1: ";

cout << " Student ID: " << s1.getStudentId();

cout << " Name: " << s1.getFirstName() << " " << s1.getLastName();

cout << " Residence: " << s1.getResidenceTown();

cout << " Scores: " ; s1.printScores();

cout << " Score Average: " << s1.getScoreAvg();

cout << " Student 2: ";

cout << " Student ID: " << s2.getStudentId();

cout << " Name: " << s2.getFirstName() << " " << s2.getLastName();

cout << " Residence: " << "Lived in " << s2.getResidenceTown(); s2.setResidence("Pleasantville");

cout << " but moved to " << s2.getResidenceTown();

cout << " Scores: " ; s2.printScores();

cout << " Score Average: " << s2.getScoreAvg() << " ";

cout << " Student 3: ";

cout << " Student ID: " << s3.getStudentId();

cout << " Name: " << s3.getFirstName() << " " << s3.getLastName();

cout << " Residence: " << s3.getResidenceTown();

cout << " Scores: " ; s3.printScores();

cout << " Score Average: " << s3.getScoreAvg() << " ";

return 0;

}
