In C++

Write a program that will simulate FCFS, SJN, SRT, and Round Robin scheduling algorithms. For each algorithm, the program should compute waiting and time and turnaround time of every job as well as the average waiting time and average turnaround time. The average values should be consolidated in a table for easy comparison. The time quantum for round robin must be input by the user, as well as the user choosing a number from 1-4 to select which algorithm to calculate.
