Question

Make a one program in c++ with output with visual studio.

1.      Make a class called Product and code for methods. It must include the three types of constructors , services ("get" and "set"), and the following operator overloading =, ==, <<, >>.

2.      Private attributes are string called productName, productBarCode, integer quantity, and type double price. The == operator will only compare against the productBarCode attribute. The +, -, ++ operators are going to modify only the quantity attribute.

Remember to validate.

3.      Make a class called Machine that will be a composition of the Product class. It must include the three types of constructors, services ("get" and "set"), and the following operator overloading =, ==, <<, >>. Private attributes are products [25] of type Product and totalProducts of type integer.

Explanation / Answer

Here is the Product class for you:

#include <iostream>
using namespace std;
class Product
{
    // Private attributes are string called productName, productBarCode, integer quantity, and type double price.
    string productName;
    string barCode;
    int quantity;
    double price;
    public:
        Product(string pN, string bC, int q, double p)
        {
           productName = pN;
           barCode = bC;
           quantity = q;
           price = p;
        }
        void setProductName(string pN) { productName = pN; }
        void setBarCode(string bC) { barCode = bC; }
        void setQuantity(int q) { quantity = q; }
        void setPrice(double p) { price = p; }
        string getProductName() { return productName; }
        string getBarCode() { return barCode; }
        int getQuantity() { return quantity; }
        double getPrice() { return price; }
        bool operator==(Product &other) { return barCode.compare(other.barCode) == 0; }
        void operator+(int q) { quantity += q; }
        void operator-(int q) { quantity -= q; }
        void operator++() { quantity += 1; }
};
