Open closed principle

Sep 10 2013 2:21 AM

Hello please explain this idea.I got this from Martin book.

They are closed for modification. Extending the behavior of a module does not result in changes

to the source, or binary, code of the module. The binary executable version of the

modulewhether in a linkable library, a DLL, or a .EXE fileremains untouched.

thanks in advance
