C++ Write a program that creates a linked list of Box Records Description Create a linked list of Boxes. Each noce in the list is a struct Box object Define a struct Box. The struct should include the following data members ID number width of a box + Height of a box + Length of a box + A "next" pointer The program will have two function bool insert and void display The program should prompt the user to enter different types of boxes, the program shoule then ask the user if he or she wishes to see the list of boxes, and display them if the user's response is yes. The screern should clear before displaying the list. The program shoule allow the user to run it repeatedly OUTPUT… Enter the specifications of different types of boxes. Inchude the number of boxes presently in inventory Enter boxes (-1 to quit) ID number 100 ID numbe 10 ID number 102 ID number 103 width: 3.25 height: 2.50 lenghth : 3.50 lenghth : 6.5 5 width: 4.00 height : 8.50 width: 3.50 height: 5.00 lenghth : 7.75 width: 2.75 height: 3.75 lenghth: 9.00 Would you like to see the list of boxes (YN) ? y -(Screen clears) Types of boxes ID# Width Height Length 103 2.75 3.75 9.00 102 3.505.007.75 101 100 3.25 2.503.50 Would you like to enter some new records (y/n) ? n Have a nice day?
