Q. Explain Common coupling with example?
Common coupling: General coupling is when two modules share the same global data (example a global variable). Changing of the shared resource implies changing all the modules using it.

It doesn't mean that a software designer must be aware of potential consequences of common coupling and take special care to guard against them.
