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 Applemac Quiz 1: 7 Quiz 2: 5 Midterm exam: 65 Final exam: 73

, 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) {}



// Mutator functions to set values

void setName(string studentName) {

name = studentName;

}
