Objectives $1.$ To understand inter $-$ process communication using message queues $.$ Prelab $1.$ Read the section that addresses message quenes in the lab manal $.2.$ Read the muamual pages of the following systems calls : #include $<$ sys $/$ types.h $>$ #include $<$ sys $/$ ipe.b #include $<$ sys $/$ nag.h $>$ int magget $($ key t key $,$ int megflg $)$ ; int megend $($ int maqid $,$ const void $*$ nsgp $,$ size$\_$t megsz $,$ int megfig $)$ ; saize$\_$t msgrev $($ int maqid $,$ void sgp $,$ size$\_$t magaz $,$ long nagtyp $,$ int nagfig $)$ ; struct Mensage long sype : char data $[15]\}$ Experiment $1.$ Write two programs and name thim send.c and receive.e to send and receive messages from a message queue respectively $.$ The aand program is exerated as follows : and Ray type data it writes the text message $"$ data into the message queue whose key is $"$ key $,$ where $"$ type $"$ is the type of the written message $.$ The receive function $,$ on the other hand $,$ is executed as follows : $1$ A $2$ B $/$ receiva kay typa it reads a message of type type from the message queue whose ley is $"$ kay if such message exists $,$ and blocks otherwise $.$ Test your code and show your work to your lah instructor $.$ Use the following message format : $5$ E $2.$ Assume you have two processes $,$ a parent and a child $.$ The parent prints the numbers from $1$ to $6,$ while child priats the characters from A to E$.$ Use a single message queue to synchronize the two processes such they produce the following output : $3.$ Une menage quees to synchronize three processes P$.$ P $,$ and P $,$ as follows $($ where P is the parent of the other two $)$ ; $($ a $)$ reads a string from the standard input and sends it to P $($ b $)$ P $,$ converts the string to uppercase and send it to P $($ e $)$ P prints the converted string to the output screen The three processes redo the above tasks forever until the user enters $"$ exit $"$ as an input string $.$
