This second edition of the book allows students to undertake a complete study of C, including the fundamental concepts, programming, problem solving, and the data structures. The book is also structured to provide a general introduction to computer concepts before undertaking a detailed treatment of the C programming language. To that end, the book is eminently suitable for the first-year engineering students of all branches, as per the prescribed syllabus of several universities, for a course on Computer Concepts and C Programming. Besides, the book fully caters to the needs of the students pursuing undergraduate and postgraduate courses in general streams such as computer science, information science, computer applications (BCA and MCA) and information technology. Written in an engaging style, the book builds the students' C programming skills by using a wide variety of easy-to-understand examples, illustrating along the way the development of programming constructs and logic for writing high-quality programs. The book also develops the concepts and theory of data structures in C, such as files, pointers, structures, and unions, using innumerable examples. The worked examples, in the form of programs and program segments, are illustrated with outputs of sample runs. A chapter on Computer Graphics is provided to give the students a feel of how C language is used for display of graphics and animation. An exclusive chapter on advanced concepts such as enumerated data types, bitwise operators and storage classes is included in sufficient detail to help students progress to writing practical and real-world applications. Besides, a new chapter presents a "C" quiz comprising of 100 objective type questions that help readers to test their C skills.
