Usually you don't mount acd0 but acd0c. This might be the
cause of the error. But you get "no such file or directory"
which means acd0c does not exist. Is this right?

As to your first question, normally only root can mount
the cdrom. So the program that does the system() will need
to be run by root as well (or be setuid root).

What commands do you use normally to mount the cd-rom?
