Modular Programming Techniques are evolving. The latest techniques in modular programming need to be investigated. This book focuses on a thorough grounding on modular programming using the latest programming approaches like Aspect-Oriented and Feature-Oriented Programming. The basic concepts of these two paradigms are given along with the implementations. The book also provides a practical application of AOP and FOP. Apart from these the meta-programming concepts are also given which is a part of FOP. The existing theories of meta-programming are analysed with its applications. The book can be helpful for understanding the future generation of modular programming with an insight of the latest trends. This book can be used for enhancing the advanced programming skills and would also prove useful for practising professionals, research scholars and academicians.
