Explanation / Answer

I think this is because you are missing a header file whose name should be product.h.

Below is the header file I created.

after adding it , it compiles perfectly fine.

product.h

#ifndef _PRODUCT_H
#define _PRODUCT_H

#include <iostream>
using namespace std;

class Product {
private:
int plu;
string productName;
int type;
double price;
double inventory;

public:
Product(int pl, string pn, int t, double pr, double i);
Product();

int getPLU();
string getProductName();
int getType();
double getPrice();
double getInventory();
double updateInventory(double quantity);
};

#endif

product.cpp

#include "product.h"

using namespace std;
Product::Product()
{
plu = 0;
productName = "none yet";
type = 0;
price = 0;
inventory = 0;
}
Product::Product(int pl, string pn, int t, double pr, double i)
{
plu = pl;
productName = pn;
type = t;
price = pr;
inventory = i;
}
int Product::getPLU()
{ return plu;}
string Product::getProductName()
{ return productName;}
int Product::getType()
{ return type;}
double Product::getPrice()
{ return price;}
double Product::getInventory()
{ return inventory;}
double Product::updateInventory(double quantity)
{
if (quantity > inventory)
cout << "This item is not in stock." << endl;
else inventory -= quantity;
return inventory;
}
