I'm having difficulty with this program where I cannot get the code to recognize my print_menu function nor does it correctly modify when prompted to do so. here is what is being asked of me to do as well as my code and its errors:

Here is my code so you can run and debug:

11.25 LAB*: Program: Online shopping cart (Part 2) This program extends the earlier "Online shopping cart" program. (Consider first saving your earlier program). (1) Extend the ItemToPurchase class to contain a new attribute. (2 pts) item_description (string) - Set to "none" in default constructor Implement the following method for the ItemToPurchase class. print_item_description() - Prints item_description attribute for an ItemToPurchase object.

Output the name and date. Create an object of type ShoppingCart (1 pt) Ex. Enter customer's name: John Doe Enter today's date: February 1, 2016 Customer name: John Doe Today's date: February 1, 2016 (4) In the main section of your code, implement the print_menu() function. print_menu() has a Shopping Cart parameter, and outputs a menu of options to manipulate the shopping cart.
