Please explain step by step how processes are created.
1. Including the parent process, how many processes are created by the following program ? Assume
that all fork() system calls succeed.
#include <unistd.h>
#include <stdio.h>
int main(int argc, char **argv) {
for (int i = 0; i < 3; i++)
fork();
/* ... */
}
2. Given the following program, please determine how many times the word “hello” is printed out.
Assume that fork() is always successful.
#include <sys/types.h>
#include <stdio.h>
int main() {
pid_t a, b;
a = fork();
b = fork();
if (a == 0)
b = fork();
if (b == 0)
a = fork();
printf(“hello\n”);
return 0;
}
