The book has been written after five years researchto find the answer of a query "Why University levelcomputer sciences students are bad in programming,"in the presence of so many books of C/C++.Authors ofthe book have hand on experience of programming andteaching, and have utilized their class roomexperience in making this book very easy tounderstand for the beginners of C/C++ programming.This book is divided in two main portions, firstportion answer the question "How to developprogramming logic," whereas second portion discussabout programming structures. One chapter of bookalso discussed about the fundamentals of computerbecause before starting programming students have toknow about the basic things.we have discussed aboutthe basic functionality and working mechanism ofC/C++ languages programs. We have extensively usedpictures to explain the programming concept.A mostimportant thing of this research book is every codementioned was tested before writing in book. We havetried our best to make book as easy as possible forthe beginners.The purpose of this book is to introduce an easyapproach and techniques, for the understandability ofCC++ programming.

The main purpose of the book is exploring the problems existing with WiMAX cryptographic suit.Book explains the basics of WiMAX and then explains security mechanism of WiMAX MAC layer. Next it explores the Study of authentication and authorization mechanism, functioning in WiMAX IEEE 802.16e using specially designed simulator. In the remaining portion of the book flaws of existing WiMAX cryptographic suit and its solutions are discussed. We designed a special simulator to test our proof that 3DES can replace DES with very minimum changes in cryptographic suit. Introduction of a new and lightweight encryption algorithm MAES in the parallel of AES in the cryptographic suit, to facilitate user of WiMAX having efficient multimedia encryption, is another main purpose of the book. The book also explains the Testing of light weight and efficient MAES on different datasets of text and images. In the last we have mentioned some new research points, which can help the researchers to generate new ideas.
