Problem. How do you create new files in a file.

This question has been bothering me for a while and I have not found any concrete examples or helpful answers as to do this. Currently, I am making a program that does very simple file manipulation.

I remember reading on a forum post on cplusplus.com about how to do this. The poster suggested using system(). Normally I would take that answer and work with it, but I've heard so many bad things about the system() function.

Would anyone be so kind enough to furnish me with an example?

Thank you.
