Write function fcfs to do the following

a$.$ Return type void

b$.$ Parameter list

i$.$ An array for the process IDs, data type int $($i$.$e$.,$ process$)$

ii$.$ An array for the arrival times, data type int $($i$.$e$.,$ at$)$

iii. An array for the burst times, data type int $($i$.$e$.,$ bt$)$

c$.$ Declare an array for the wait times, data type int $($i$.$e$.,$ wt$)$

d$.$ Declare an array for the turnaround times, data type int $($i$.$e$.,$ tat$)$

e$.$ Initialize index $0$ in array wt to $0$

h$.$ Calculate the wait times for each process

i$.$ Iterate for the number of processes $($i$.$e$.,$

PID

$)$ starting at

index $1$

$1.$

Set the wait time in array wt at the current index

equal to the sum of burst time $($i$.$e$.,$ bt$)$ of the

previous i

ndex and wait time $($i$.$e$.,$

w

t

$)$ of the

previous index

i$.$ Calculate the turnaround times for each process

i$.$ Iterate for the number of processes $($i$.$e$.,$

PID

$)$

$1.$

Set the turnaround time in array ta

t at the current

index equal to the sum of burst time $($i$.$e$.,$ bt$)$ of the

current

index

j$.$ Call function displaySchedule passing arguments

i$.$ Array process
