c - Fork system call not exiting -


i've run following code :

#include  <stdio.h> #include  <sys/types.h> int main() {     fork();     fork();     fork();     printf("hello\n");     return 0; }

after printing word "hello" 8 times, program not exiting. reason behind this?

this accidentally interesting way calculate 2^3. first fork makes second fork happen twice , each make third fork happen twice , 8 children run printf! 8 processes exit, prompt lost in noise.

as commenters implied, fundamentally misunderstanding fork() , doing. along way made interesting toy, bravo!
