In java it is possible to light a led by simply sticking a LED into ceirtan holes of the printer port, you also need some code... but my question is how would you do something like this is C++?

The same way as in Java, you just need to set the appropriate pins to "on".
Heck, you can do it in DOS from the prompt...

A quick google:
