How to Predict Reusability Index of a Standalone Code

Is it possible to predict the reusability index of a block of code in a standalone mode? Meaning, given no information about the code, and just the piece of code, would you be able to predict or tell if the code is highly reusable or not reusable at all? Before going into this, lets understand the basic fundamentals in relation with code reusability. One myth I have come across while discussing the code reusability is that code should be made reusable when demanded by requirements. For example, one says that for reusable services, one should write reusable components and thus, reusable piece of code. When asked to many people, I …
