What would get printed in the following code which contains POSIX standard notation with prefix p? (Hint: There may be zero, one, or multiple answers.)

void main() {

pthread_t thread; /*define Posix thread*/

pthread_create(&thread, NULL, &helper, NULL);

printf("Hello World! 2 ");

exit(0);

}

void *helper(void* arg) {

printf("Hello World! 1 ");

pthread_exit(0);

}
