(160814) - DUE 23 August 2024;100% TRUSTED workings,
explanations and solutions.
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
To convert the given structure into a class and implement the
required functionalities, follow these steps:
1. Define the Student class with private member variables.
2. Implement public member functions for setting
(mutators) and retrieving (accessors) these variables.
3. Include a function to calculate and return the student's
weighted average numeric score.
4. Write a program to use this class to read input, calculate
the average, and display the results.
Here’s the complete implementation in C++:
cpp
Copy code
#include <iostream>
#include <string>
#include <iomanip> // For setting precision
using namespace std;
// Define the Student class
class Student {
private:
string name;
int quiz1;
int quiz2;
