Help with c++ problem
1. Create a Retail Store Class. The class has a cash register, a collection of inventory objects. It sells various items in its inventory to its customers, it purchases more quantities of items in stock from its suppliers; it purchases quantities of new items from its suppliers. It computes its profit or loss by subtracting the cost of its inventory from its retail sales. The retail store reads and writes its inventory collection, its sales to customers records and it purchases from wholesalers records to and from files.
2. Write a program that simulates the operations of a retail store. The program reads commands from a file. The commands tell the store to purchase inventory items from whole sellers, sell items to customers, displays the stores profit/loss position, read the store's records from files, write the store's records to files.
here are the classes for the problems

Here is the CashRegister class
//CashRegister.cpp file
//include header file CashRegister.h into the CashRegister.cpp
#include"CashRegister.h"
CashRegister::CashRegister(double price, double profit, double subtotal, double tax)
{
this->price=price;
this->tax = 0.06; //6 percent of tax on items
//call parent class getCost and getOnHand to calculate the subtotal of items
this->subtotal=getCost()*getOnHand();
this->profit=profit
}
double CashRegister::getItemPrice() const
{
return price;
}
double CashRegister::getTax() const
{
return tax;
}
double CashRegister::getProfit() const
{
return profit;
}
double CashRegister::getSubtotal() const
{
return subtotal;
}
------------------------------------------------------
question 5 is basically a simulator that will combine all these codes together
Explanation / Answer
1)
caaling cashRegister methods by creating new object
#include 'CashRegister.h'
CashRegister::CashRegister(){
}
void main(){
CashRegister CR(12.00,3,24,4);
cout<<b.getItemPrice();
cout<<b.getTax();
cout<<b.getProfit();
cout<<b.getSubtotal();
}
