Money Class Requirements Negative amounts of Money shall be stored by making bot

Question

Money Class Requirements Negative amounts of Money shall be stored by making both the dollars and cents negative The Money class shall have 4 constructors * A default constructor that initializes your Money object to $0.00 *A constructor that takes two integers, the first for the dollars and the second for the cents *A constructor that takes one integer, for an clean dollar amount A constructor that takes one double, and can assign dollars and cents accordingly - int getPennies const e Returns the equivalent amount of money as a number of pennies - bool isNegative ) const Returns true if your amount of money is negative - void add (const Money &m;) * The sum shall be stored in the calling object -void subtract (const Money &m;) *The difference shall be stored in the calling object bool isEqual (const Money &m;) - void print) const * This function prints the amount of Money you have, it must print a .$,' and always show two decimal places *Negative amounts of Money shall be represented in the following manner: (SX.XX) The Money class shall have two private data members

Money.h
=========

#ifndef Money_h
#define Money_h

class Money
{
private:
int dollars, cents;
public:
Money();
Money(int dol, int cen);
Money(int dol);
Money(double amt);
int getPennies() const;
bool isNegative() const;
void add(const Money &m);
void subtract(const Money &m);
bool isEqual(const Money &m);
void print() const;
};

#endif /* Money_h */

Money.cpp
=========

#include "Money.h"
#include <iostream>
using namespace std;
Money::Money()
{
dollars = 0;
cents = 0;
}
Money::Money(int dol, int cen)
{

//keep the dollar and cents adjusted. Don't let cents to be be 100 or more
if(cents > 100)
{

cents %= 100;
}
  
}
Money::Money(int dol)
{
dollars = dol;
cents = 0;
}
Money::Money(double amt)
{
dollars = amt;
cents = (amt * 100 - dollars * 100);
}
int Money::getPennies() const
{
return dollars * 100 + cents;
}
bool Money::isNegative() const
{
if(dollars < 0 || cents < 0)
return true;
else
return false;
}
void Money::add(const Money &m)
{
int pennies = getPennies() + m.getPennies();
dollars = pennies / 100;
cents = pennies % 100;
}

void Money::subtract(const Money &m)
{
int pennies = getPennies() - m.getPennies();
dollars = pennies / 100;
cents = pennies % 100;
}
bool Money::isEqual(const Money &m)
{
if(getPennies() == m.getPennies())
return true;
else
return false;
}
void Money::print() const
{
if(isNegative())
cout << "$(" << -dollars << "." << -cents << ")" << endl;
else
cout << "$" << dollars << "." << cents << endl;
  
}

TestMoney.cpp
============

#include <iostream>
#include "Money.h"
using namespace std;
int main()
{
Money m1;
Money m2(25, 99);
Money m3(50);
Money m4(95.25);
Money m5(25.99);
  
cout << "m1 = "; m1.print();
cout << "m2 = "; m2.print();
cout << "m3 = "; m3.print();
cout << "m4 = "; m4.print();
cout << "m5 = "; m5.print();
  
if(m3.isNegative())
cout << "m3 is negative" << endl;
else
cout << "m3 is not negative" << endl;
  
if(m2.isEqual(m5))
cout << "m2 is equal to m5" << endl;
else
cout << "m2 is not equal to m5" << endl;
  
cout << "Adding m2 to m3" << endl;
m3.add(m2);
cout << "m3 = "; m3.print();
  
cout << "Subtracting m4 from m5" << endl;
m5.subtract(m4);
cout << "m5 = "; m5.print();
  
  
return 0;
}

output
=====
m1 = $0.0
m2 = $25.99
m3 = $50.0
m4 = $95.25
m5 = $25.99
m3 is not negative
m2 is equal to m5
Adding m2 to m3
m3 = $75.99
Subtracting m4 from m5
m5 = $(69.26)
