In C++ using pointers and structures please!!!

Create a shopping cart for the user. Use a data structure of your choice to store what the user has selected to purchase. Remember the user can add as many items to their cart as there are in the inventory list.

a. You need to be able to search through the shopping cart.

b. If a person enters in a duplicate item that is already in the cart then it should increase the qty in the cart. You need to make sure that you have enough inventory to support the change.

c. Do not worry right now about the user removing anything in the cart.
