Goal

Practice process creation and communication in UNLX using fork$()$ and pipo$()$ system

calls.

Reference: the textbook chapter $3($Processes$)$

Description

Please read the complete assignment document carefally before starting.

Write a C program which will have to create a child process. Then you must use ordinary

pipe$($s$)$ to implement a half$-$duplex communication between the parent process and the

child process where both processes can exchange messages.

To test your program the parent and child will exchange some meseages, the parent will start

first by sending the first message, then the child will respond Messages should get

exchanged through pipes, and each message received fiom both parties should get displayed

on the screen. A delay of $2$ seconds should be added between each consecutive meseage

display $($you can wese the s$1$eep $()$ function for this$).$

The output of your program should look exactly like this $($in total $4$ exchanges of messages

between Parent and Child processes$)$:

Greetings son

Hello dad

How are you son

Fine dad thanks

$...$ Program finished with exit code $0$

Pxess ENTER to exit console$-$

You should implement one read and one write buffers to send and to receive messages e$.$g$-$

char Ur$1$te nsg $[$BUEEER$.$ SIZE$]$;

char read$\_$nsg$[$RUFEER$\_$SIZE$]$;

Buffers declaration shoald be done in the na in $()$ function $($first two line right after

main $()$ ks Use st rcpy $()$ function; to assign$/$update a message in a buffer.
