Programming & Computer Science Answers

For this final assignment, you will use Qt to create a GUI version of the templated LinkedList you made for assignment 9.  

You may design your window as you wish, but it needs to have the minimum functionality:

• Radio buttons to select between the different types of data your linked list will store(int, double, string, Rational, Date, Complex)
• A button to display the contents of the linked list
• The ability to display only a portion of the linked list
• Buttons to push_back, push_front, pop_front, insert_sorted
• Insert button that can insert an element at any spot in the list (have to define a new function in linked list class)
• Button to perform select_sort
• Button to remove_duplicates
• Should have the ability to make a copy of a list and be able to retain and modify both copies (may make multiple copies).
• Be able to modify any of the lists without losing any information going from one list to the other.
• You may use vectors as long as you use your own vector class, not the one provided with C++/QtCreator.

You are requested by a SuperStore (Spar) in Soshanguve to calculate it’s earning for the week (the store opens the entire week) and determine the day with the highest and lowest earnings. The Store comprises of two sections namely the Food section and the Liquor store. Your C++ program should prompt the total sales for each section for each day and store the total sales for the day into an array. At the end of the week It should display a report for Management for the total sales for that week, the day the lowest sales and the day with the highest sales were recorded.

1. Assuming standard 1500 byte Ethernet max payloads: how many IPv4 fragments will be needed to transfer 2000 bytes of user data with a single UDP send? And, how do the 2000 bytes get split over the frags?
2. Despite its conceptual elegance, RPC (Remote Procedure Call) has a few problems. Discuss any 3 of those in brief.
3. Why is timestamping needed in real-time applications? This is in the context of Real-time Transport Protocol (RTP).
4. Why does UDP exist? Would it not have been enough to just let user processes send raw IP packets?
5. Explain how QUIC eliminates a couple of RTTs usually needed at the start of a secure web connection.
