. Write a C program to create an unnamed pipe. The child process will write following three messages to pipe and parent process display it. Message1 = “Hello World” Message2 = “Hello SPPU” Message3 = “Linux is Funny”

#include<stdio.h>
#include<unistd.h>
int main() {
int pipefds[2];
int returnstatus;
char writemessages[3][20]={"Hello World", "Hello SPPU","Linux is Funny"};
char readmessage[20];
returnstatus = pipe(pipefds);
if (returnstatus == -1) {
printf("Unable to create pipe\n");
return 1;
}
int child = fork();
if(child==0){
printf("Child is Writing to pipe - Message 1 is %s\n", writemessages[0]);
write(pipefds[1], writemessages[0], sizeof(writemessages[0]));
printf("Child is Writing to pipe - Message 2 is %s\n", writemessages[1]);
write(pipefds[1], writemessages[1], sizeof(writemessages[1]));
printf("Child is Writing to pipe - Message 3 is %s\n", writemessages[2]);
write(pipefds[1], writemessages[2], sizeof(writemessages[2]));
}
else
{
read(pipefds[0], readmessage, sizeof(readmessage));
printf("Parent Process is Reading from pipe – Message 1 is %s\n",
readmessage);
read(pipefds[0], readmessage, sizeof(readmessage));
printf("Parent Process is Reading from pipe – Message 2 is %s\n",
readmessage);
read(pipefds[0], readmessage, sizeof(readmessage));
printf("Parent Process is Reading from pipe – Message 3 is %s\n",
readmessage);
