Question

Define and implement a class, Report, that has these members

Private members :

adno 4 digit admission number

nam string

marks an array of 5 real values

average average marks obtained

Public members:

Default constructor

Constructor with the four data members

Copy constructor

Operator+()

Operator<<() //Make sure the output looks like display explicitly written in the driver.

Operator>>() //Use the example run as your guide

Operator>()

Operator<()

Operator==()

Get() for each data member

Set() for each member

Operator++ for prefix

Operator—for prefix

setAVG() a function to compute the average obtained in five subjects

Type your solution in the program shell to your left as commented.

Here is an example run of the solution

Display ri Student ID 9933 Student Name: Pete Luckman Student Average: 85.4 Display r2 Student ID 6273 Student Name James Smythe Student Average: 81.6 Enter the marks for r3. mark #1: 100 mark #2: 40 mark #3: 76 mark #4: 89 mark #5: 63 Thank you! Display r3 Student ID 6284 Student Name: James Smythe Student Average: 73.6 Comparisons. Compare r2 == r3: Different average Compare ri> r2: ri is greater Compare r3< ri r3 is less or equal Add r1 and r2: 167 Increment r3 Student ID 6284 Student Name: James Smythe Student Average: 74.6 Decrement r2 Student ID 6273 Student Name James Smythe Student Average: 80.6 End of program

Here is the Code to start. Do not change int main().

#include <iostream>
#include <string>
using namespace std;

//Define class here

int main(){
double d[5] = {90, 87, 53, 85, 93};
Report r1;
Report r2(6273, "James Smythe", d);
  
r1.setAdno(9933);
r1.setName("Pete Luckman");
r1.setMarks(45, 78, 99, 72, 88);
r1.setAVG();
  
  
cout << "Display r1\n===================================\n";
cout << " Student ID: " << r1.getAdno();
cout << "\n Student Name: " << r1.getName();
cout << "\n Student Average: " << r1.getAvg();
cout << "\n===================================\n\n";
  
cout << "Display r2\n===================================\n";
cout << r2;
cout << "\n===================================\n\n";
  
Report r3 = r2;
cout << "Enter the marks for r3...\n\n";
cin >> r3;
cout << "Thank you!";
cin.get();
cout << "\n\nDisplay r3\n===================================\n";
cout << r3;
cout << "\n===================================\n\n";
  
cout << "Comparisons...\n========================================\n";
cout << "Compare r2 == r3: "
<< ((r2 == r3) ? "Same average" : "Different average") << endl;
cout << "Compare r1 > r2: "
<< ((r1 > r2) ? "r1 is greater" : "r2 is greater or equal") << endl;
cout << "Compare r3 < r1: "
<< ((r1 < r3) ? "r1 is less" : "r3 is less or equal") << endl;
cout << "========================================\n\n";
  
cout << "\nAdd r1 and r2: " << r1 + r2 << endl;
  
cout << "\nIncrement r3: " << ++r3 << endl;
  
cout << "\nDecrement r2: " << --r2 << endl;
  
cout << "\n\n---------------\nEnd of program..." << endl;
  
return 0;
  
}
