This question is off topic in this group -- not in standard C.

<OT> ask in a newsgroup appropriate to your system about fork (may
be helpful). Also, possible that system("B &"); will do
something useful. But issues with those are system specific,
and should be discussed elsewhere </OT>

See my rely in your other thread.

The short summary is:

There is NO standard way to do that in standard C.
There might or might not be methods provided by your operating system,
but those are not part of the C standard and you need to ask elsewhere
about those.

There is no standard C solution. More or less standard extensions exist
(like the POSIX Threads). Note that if you have only one processor, true
concurrent execution is not possible.

this is as simple as sex. once you start doing a girl, make a command
that another one doing another girl or your girl. when you finish, halt
the other one.
