FCFS implementation in C

Simulation of FCFS CPU scheduling algorithms to find turnaround time and waiting time




We are given with n processed with there arrival time and burst time,task is to find average waiting time and average turn around time.

Algorithm is simple as waiting in lines for our order in a burger shop where the first person is served first from where we get the FCFS as First Come First Serve also known as First in First out.

Things to remember

  • FCFS is a non-pre-emptive scheduling 
  • Avg waiting time is not optimum compared to other scheduling
  • Has Convay effect
