C Code FCFS First Come First Served Process Scheduling | Operating System

Write the programs to implement in C Code FCFS First Come First Served Process Scheduling   CPU scheduling algorithms. Take the inputs, Process name, Arrival time of the process, CPU execution time of the process. Use system timer to check the  time quantum and display after every second the process running on the CPU or if the CPUis idle until all the inputted
processes complete their execution. Calculate waiting time, turn around time for each
process.

 

 In this problem we can use time_t and get system time using time() which in the <time.h> header file so we need to import it also.Following Solution only for FCFS
