Subject Algorithm and Data Structure

Question

Write a menu-based program to create a list of records (at least 3 data) using the queue concept. Your program should be able to perform the following queue operation.

1. Enqueue
2. Dequeue
3. Queue rear
4. Queue front
4. View
5. Exit

This program is designed using a Structure which is a computer and its components. It has the ability to receive input from a user. It starts by asking the user their name. After it has been input, the screen clears, then it proceeds to ask the user if they need to fill in 5 orders for the computer with a Yes or No option.

If the user says no, the screen clears and the program will terminate. If the user says yes, the screen clears and the program proceeds to ask the user to input details such as the mainboard name, processor cores, ram size, hard disk size, and power wattage for 5 pcs. The final output then displays in a table all the components for all the PCs. If the input is invalid, the user will be asked to re-enter a valid value.
