Question

I. Create the class Item with the following members:
1. id, a protected variable of type int
2. name, a protected variable of type string
3. price, a protected variable of type double
4. a public non-default constructor which accepts three parameters to initialize the variables above
5. a copy constructor
6. overload the = operator such that both operands are of type Item
7. overload the = operator such that the right operand is of type double. Assign the value of double to the price member

Answer 1

Thanks for the question, here is the class Item in C++

===============================================================

class Item{
   protected:
       int id; string name; double price;
   public:
       Item(int id, string name, double price);
       Item(const Item& item);
       void operator=(const Item& item);
       void operator=(double price);
};
Item::Item(int id, string name, double price): id(id),name(name),price(price){}
Item::Item(const Item& item){
   id = item.id;    name = item.name;    price = item.price;
}
void Item::operator=(const Item& item){
   id = item.id;    name = item.name;    price = item.price;
}
void Item::operator=(double price){
   this->price = price;
}
