Fork without waiting

Question

I'm not sure if I will do it right, I'm trying to create only 7 processes through ...

void err_sys(const char* x)
{
   perror(x);
   exit(1);
}


for(i = 1; i < 7; i++){
  switch(parent = fork()){
      case -1:
         err_sys("fork error");
      case 0:       //child
         printf("I'm the child, number %d(%d)\n", i, getpid());
         break;
      default:      //parent
         printf("I'm the parent(%d)\n", getpid());
         break;
  }
    if(parent)
       break;        //loop break
}

When I run it with prog | cat> file I get 6 exits from "I am a parent", followed by different numbers of children. However, there are 6 children with unique drinks. Other parent pids other than the first correspond to the child pid. Are these just some of the problems associated with quitting due to forking?

1, 2, 3, 4, 5, 6 . :

for (i = 0; i < 7; i++)      // Idiomatic C
for (i = 1; i <= 7; i++)     // Less idiomatic C

, err_sys() ( , break; ), :

• . , err_sys().
