Scheduling Algorithms: (Reference: OS Book Chapter 6)

Write a program in c++ language to implement the Multilevel Feedback scheduling using 3 levels/queues, each one implementing the following:

1. Level 1/Queue 1: Round Robin scheduling algorithm with quantum (q=8).

2. Level 2/Queue 2: Round Robin scheduling algorithm with quantum (q=16).

3. Level 3/Queue 3: First Come First Serve scheduling

a) The user should be able to enter the number of processes, their arrival times and their burst times in time units. Data entry can be through console or graphical interfaces.

b) Your program should find, select and display the order in which the processes are executed (it will be nice if you can draw the Gantt chart) and the start and end of each execution cycle (you can add the length of the execution cycle).

c) Add an option to specify the percentage of the CPU time for each queue as follows:

1. Level 1/Queue 1: 60%

2. Level 2/Queue 2: 25%

3. Level 3/Queue 3: 15% At the end, do the following calculations and display them:

1. the average waiting time

2. the average response time

3. the average turnaround time

Example of Multilevel Feedback Queue D Three queues: D Q0RR with time quantum 8 miliseconds D Q1 - RR time quantum 16 miliseconds - Q2 - FCFS - Scheduling D. A new job enters queve Qo which is served RR - When it gains CPU, job receives 8 millseconds - If it does not finish in 8 milliseconds, job is moved to queve Q1 D. At Q1j0b is again served RR and receives 16 additional milliseconds - If it stil does not complete, it is preempted and moved to queue Q2
