This book is meant for undergraduate students and users of MATLAB programs and those who want to be in pace with the developing technology. As C is used in a variety of areas from software development to hardware programming, including embedded system or driver writing or system programming, it is essential to have knowledge of this particular language. This book will serve a large spectrum of programmers as well as MATLAB users of various fields both in academia and scientific research. This book is arranged in two sections, namely, C11 and MATLAB. C11 section includes on the spot explanation of the program structure/ skeleton in the beginning and leads towards larger program development by using various basic building materials of the language. This book mostly depicts programs using the concept discussed in that chapter. MATLAB section is included for the UG students to have sound knowledge of MATLAB so that they can use this language for their research purposes.
