Question

Write a C++ class named CashRegister. The class should have private data members named
Hundreds, Tens, Fives, and Singles all of type integer. The class should have the following:
1. A member function named GetTotalCash to retrieve the total cash inside the cash
register.
2. Overload the + operator to allow adding two objects of type CashRegister (note, add the
hundreds to the hundreds, tens to tens and so on).
3. Overload the > operator to compare between two CashRegisters objects based on their
totalcash.
4. Overload the += operator.

Thank you

Please find the code below:

#include <iostream>
using namespace std;

class CashRegister{
private:
   int hundreds;
   int tens;
   int fives;
   int singles;
public:
   CashRegister(){

   }
   CashRegister(int h,int t,int f,int s){
       hundreds = h;
       tens = t;
       fives =f;
       singles = s;
   }

   int GetTotalCash (){
       return hundreds * 100+tens*10+fives*5+singles;
   }

   CashRegister operator + (CashRegister const &obj) {
       CashRegister res;
       res.hundreds = hundreds + obj.hundreds;
       res.tens = tens + obj.tens;
       res.fives = fives + obj.fives;
       res.singles = singles + obj.singles;
       return res;
   }

   bool operator > (CashRegister &obj) {
       return GetTotalCash()>obj.GetTotalCash();
   }

   void operator += (CashRegister const &obj) {
       hundreds = hundreds + obj.hundreds;
       tens = tens + obj.tens;
       fives = fives + obj.fives;
       singles = singles + obj.singles;
   }

   int getFives() const
   {
       return fives;
   }

   int getHundreds() const
   {
       return hundreds;
   }

   int getSingles() const
   {
       return singles;
   }

   int getTens() const
   {
       return tens;
   }

   void setFives(int fives)
   {
       this->fives = fives;
   }

   void setHundreds(int hundreds)
   {
       this->hundreds = hundreds;
   }

   void setSingles(int singles)
   {
       this->singles = singles;
   }

   void setTens(int tens)
   {
       this->tens = tens;
   }

};

int main(){

   CashRegister r(1,2,3,4);
   cout<<"First object cash value is : "<<r.GetTotalCash()<<endl;
   CashRegister r2(4,3,2,1);
   cout<<"Second object cash value is : "<<r2.GetTotalCash()<<endl;

   CashRegister r3 = r+r2;
   cout<<"Third object cash value is : "<<r3.GetTotalCash()<<endl;

   bool res = r>r2;
   cout<<"First > Second ? "<<res<<endl;

   r +=r2;
   cout<<"First object cash value is : "<<r.GetTotalCash()<<endl;

   return 0;
}

output:
