#define max 20

int main()

{

            int fd[2],pid;

            char l[max];

            pipe(fd);

            if((pid=fork())<0)

            {

                        printf("error");

            }

            else if(pid>0)

            {

                        close(fd[0]);

                        printf("enter the msg");

                        scanf("%s",l);

                        write(fd[1],l,12);

            }

            else

            {

                        close(fd[1]);

                        read(fd[0],l,12);

                        puts(l);

            }
