Question

You will work with MyInteger class (like an int, but it will be an object) by obtaining the two files, MyInteger.h and testMyInteger.cpp. Create the file MyInteger.cpp by implementing the member and friend functions for the class.

==============MyInteger.h==============

#ifndef MYINTEGER_H

#define MYINTEGER_H

#include <iostream>

using namespace std;

class MyInteger

{

public:

MyInteger(int v = 0);

void setValue(int v);

int getValue() const;

MyInteger operator+(const MyInteger &r) const;

MyInteger operator-(const MyInteger &r) const;

bool operator==(const MyInteger &r) const;

friend ostream &operator<<(ostream &out, const MyInteger &r);

friend istream &operator>>(istream &in, MyInteger &r);

private:

int value;

};

#endif

==============testMyInteger.cpp==============

// A driver to test MyInteger class

#include <iostream>

#include "MyInteger.h"

using namespace std;

int main()

{

MyInteger i1; // 0

MyInteger i2(5); // 5

MyInteger i3 = i2; // 5

cout << "i1: " << i1 << endl;

cout << "i2: " << i2.getValue() << endl;

cout << "i3: " << i3 << endl;

i1.setValue(-4);

i3 = i1 + i2;

cout << "i3: " << i3 << endl; // 1

cout << "i2 - i1: " << i2 - i1 << endl; // 9

cout << "Enter an integer: ";

cin >> i1; // enter 123

if (i1 == i2) // different

cout << "same" << endl;

else

cout << "different" << endl;

i2 = i1;

if (i1 == i2) // same

cout << "same" << endl;

else

cout << "different" << endl;

i2.setValue(25);

cout << "i1: " << i1 << endl; // 123

cout << "i2: " << i2 << endl; // 25

// feel free to add more test cases below

return 0;

}

PLEASE GIVE IT A THUMBS UP, I SERIOUSLY NEED ONE, IF YOU NEED ANY MODIFICATION THEN LET ME KNOW, I WILL DO IT FOR YOU

MyInteger MyInteger::operator+(const MyInteger &r) const
{

    m.value = value + r.value;
    return m;

    return false;

    return out;
}
