- Introduction to Round Robin Schedule with a Priority Round Robin (RR) with a priority is a CPU scheduling algorithm where each process is assigned a fixed time slot in a cyclic way Assume there are 5 processes with a structure of a Process Control Block (PCB): 1.Process ID: identify each process. 2.Priority: integer 0-100, the bigger the number is, the higher the priority is. The number will be decreased by 1 once a process has done for a quantum. 3.Execution time (user input): how many ms a process needs 4.Status: Ready (initialized), Terminated and currently running. Represented by letter "F" and "r" respectively. To simplify our simulation, we assume all the 5 processes arrive at the same time 0. Also, we do not require you to implement a cyclic linked list to connect all 5 processes structure using pointers. We define the structure of PCB in source code and simply store them in an array, and looping each PCB every time we use them. -Complete Source Code Read the source code and rest comments, try to understand the function of each line of code Follow the instructions in the comments and insert proper code into the rest 8 blocks to implement a CPU scheduling with RR/Priority. (C/C++ files are acceptable). Read the requirements carefully, because some blocks require exact syntax Play the program for a while and observe how it works. Now we run a specific simulation: (1) take the last five digits reversed and set them as the priority (2) set their running time 1, 2, 3, 4, 5 respectively. (3) Gives any five id your like to the 5 processes For example, my banner id is 903908281 , then the last 5 reversed digits 1 , 8,2, , . and i call 5 process "AA", "BB", "CC", "DD", "EE", then my entire setup for 5 process will be: process idpriorityrunning time 8 2 0 4 0 5
