Question 1

Consider the following structure used to keep record of a student’s scores: struct Student {

string name; int quiz1; int quiz2; int midtermExam; int finalExam; } A student is assessed

according to the following policies:

1. The two quizzes are each marked out of 10.

2. The midterm exam and the final exam are each marked out of 100 marks.

3. The final exam counts for 50% of the grade, the midterm counts for 25%, and the two

quizzes together count for a total of 25%. (Do not forget to normalize the quiz scores. They

should be converted to a percentage before they are averaged in.) Turn the student record

into a class type rather than a structure type. The student record class should have member

variables for all the input data. Make all member variables private. Include public member

functions for each of the following:

• a default constructor that sets the student ‘s name to a blank string, and all the scores to 0;

• member functions to set each of the member variables to a value given as an argument to

the function (i.e. mutators);

• member functions to retrieve the data from each of the member variables (i.e. accessors);

• and a function that calculates and returns the student’s weighted average numeric score for

the entire course. Use this class in program which grades a student. The program should read

in the student’s name and scores and output the student’s record as well as the student’s

average numeric score for the entire course. Use the keyboard to supply input and display the

output on the screen. Test your program with the following input: Student name: Johnny

Here's how you can implement the described class in C++:

cpp

Copy code

#include <iostream>

#include <string>

using namespace std;




class Student {

private:

string name;

int quiz1;

int quiz2;

int midtermExam;

int finalExam;




public:

// Default constructor

Student() : name(""), quiz1(0), quiz2(0), midtermExam(0), finalExam(0) {}
