When I attempted to write my first object oriented program with some meaningful complexity I was hit by the problem of cyclic/circular dependency. As the name suggests the problem definition is very simple. If we need to design two classes which need to call functions of each other directly how do we accomplish that? And what are the issues we may land up into if we do not pay proper attention to avoid circular dependency among them. I am sure this problem would have come up with many other programmers like me. In this post I would like to get in depth of this problem and explain why its call an anti-pattern and what are possible approaches to avoid it.
