Pipe System Call in Linux

Write a C program to run on Linux to do the following.

1. Parent process creates a pipe using the pipe() system call.

2. Parent process creates a child process.

3. Parent process sends a message "Hello from Parent" to the child.

4. Child process prints the message to the screen.

C Code:

#include <stdio.h>
#include <unistd.h>
#include <stdlib.h>

int main(){
    int pid,pipe_ends[2];
    char received_string[20];

    pipe(pipe_ends);
    pid=fork();
   
    if(pid>0){
    close(pipe_ends[0]);
    write(pipe_ends[1], "Hello From Parent", 18);
    close(pipe_ends[1]);
    exit(0);
    }
    else{
    close(pipe_ends[1]);
    read(pipe_ends[0], received_string, 18);
    printf("Message - %s\n", received_string);
    close(pipe_ends[0]);
    exit(0);
    }
}
