Implementation of dual-process operation in C language under Linux

Topic

Write a Linux C program, in the main process to create a child process, the child process in the dead loop output "Hello CSU" string, the main process sleep 10s, the child process to send a signal to end the child process, and then the main process exits. (Signaling for interprocess communication, kill function)

Code

#include <stdio.h>#include <signal.h>#include <sys/types.h>#include <unistd.h> #include <stdlib.h>void Main () {pid_t pid; printf ( "program is starting\n"); Pid=fork (); switch (PID) {case- 1: exit (0); break; case  0: while ( 1) {Sleep (1); printf ( "Hello world\n");} break; default:sleep (10);//signaled the terminating signal 
 printf ("End subprocess \ n"); Kill (PID, SIGTERM); break;}
