How to wait for *all* children processes to return?

Question:

write a program which creates 5 processes (in addition to
itself). One of these processes must display 1, another must display 2
.... the last one displays 5. The parent process waits until all other
processes are finished, then returned.

This isn't a question; it's an imperative.
I dispute your right to command me, o loud king,
and refuse to obey. Push me, and you'll have a
