Round-Robin (RR): Write a Java program to implement a Round-Robin (RR) scheduling algorithm with quantum q that will be entered by user. Your program should first prompts the user to input a list of process ID, arrival time, and burst time (in ms) for each process to be run on the CPU. The list is terminated by 0 0 0 for the process ID, arrival time, and burst time. The program output should draw a Gantt chart (as text) that shows the scheduling order of the processes using the RR scheduling algorithm. Also print the turnaround, response, and waiting time for each process along with their average for all processes. Make sure to display very helpful messages to the user for input and output.

Java programming: What's the output of the following program... a.) Compilation Error b.) 97~B~C~D~E~102~G~ c.) 65~b~C~d~E~70~G~ d.) a~66~C~68~E~f~G~

A fast food restaurant is planning to develop a system to process customer’s orders. The system receives food orders from the users, and stores and processes according to the order in which the users placed the orders. The system can remove an order from the list of orders once the order is complete. The system can also display the order which is currently being processed by the employees. The system displays the list of orders as well. The system displays all these options as a menu of choices to a user and performs the operations according to the user’s selection. (Please see the test runs on the next page). Write a program in C/C++ to develop a simple order processing system for the fast-food restaurant. In your program, you must use queue to store and process customer’s orders. Your program must use a linked list to perform the queue operations. Your output format should be as shown in the test runs (see the next page). Your program must contain the following user-defined…

Consider the following common task done repeatedly:• Read the next input (x = read())• If the input is not valid (valid(x)), exit the loop• Print the input read (print(x))• Repeat the loopUsing C++ syntax:Write the loop above using a pretest loop, posttest loop and a user-located loop control mechanism. From the three which one is more readable and why?
