1. Create a struct named Product with the following public properties to be used by the Store class below a. name, type string, b. price, type double c. quantity, type int 2. Develop a class named Store with the following private members. a. n, type integer b. products, dynamically allocated array of Product 3. Add a default constructor that a. Sets n to 0 b. products to nullate 4. Add a defined constructor that a. takes an integer p as its parameter. p should be greater than 0 (validate, if not then set n to 0 and products to nullat). b. If p is greater than 0 then set p to n and ask user to input the details of n products (place each product in the products array) i.e. for each product the following information is to be entered i. name, a non-empty string ii. price, a double value that is 0 or greater, user may input any double value greater than 0 but the value is rounded to 2 decimal places before being placed in the products array iii. iv. quantity, an integer that is greater than 0 If user makes a mistake then they have to reenter the details of that product c. At the end the products array should contain n valid (see above for restrictions) products. 5. Add a copy constructor that a. Creates a deep copy of a store 6. Add a destructor that a. Frees up dynamically allocated memory 7. Overload the following operators for your class a. =: Creates a deep copy of the store on the right hand side of the operator i. For example, suppose that there are two stores s1 and s2, then s2 = s1; will create a deep copy of s1 and set it to s2 b. <<: Outputs n, then all n products (including all information for each product). You decide on formatting, all information must be clearly visible, two consecutive products must be separated clearly c. >>: Asks user to input a non-zero integer k (must repeatedly validate until a non- zero value is received) then user inputs k product's information and these are added to the products array, n increases by k, for each product user inputs i. name, a non-empty string
ii. price, a double value that is 0 or greater, user may input any double value greater than 0 but the value is rounded to 2 decimal places before being placed in the products array iii. quantity, an integer that is greater than 0 iv. If user makes a mistake then they have to reenter the details of that product d. +: Can be used in two ways i. e. Union of two stores, s1+ s2 returns a new store that contains products from stores s1 and s2 (products with same name (case-insensitive matching) and price must have their quantities added together rather than creating separate products) ii. when used like s1 + t where s1 is a store and t is an integer then user has to add t products to the store. for each product user inputs 1. name, a non-empty string 2. price, a double value that is 0 or greater, user may input any double value greater than 0 but the value is rounded to 2 decimal places before being placed in the products array 3. quantity, an integer that is greater than 0 4. If user makes a mistake then they have to reenter the details of that product -: Can be used in two ways i. Unique elements between two stores, s1 - s2 returns a new store that contains only the unique items from stores s1 and s2, uniqueness is determined based on product name (case-insensitive matching) and price. ii. When used like s1 - t where s1 is a store and t is an integer, this operation removes t products from the store. If store has less than or equal to t products then all products are removed. Otherwise, User inputs names of products to remove one at a time (if product does not exist then ignore that input, if multiple products match that name then remove them all). 8. Write a main method and test all features of the class. 9. You are welcome to add more data members and/or method members to the class as you deem necessary.
