This book will help students to learn C programming language, and at the same time, it will allow the students to learn how to build one's own programming language, a minimal LISP in fewer than 1000 lines of code. The concepts of the C programming language are used in almost all engineering disciplines and, therefore, this textbook is essential for all students to grasp the basics of the language. This will be an indispensable textbook not only for the students of Computer Science, but will also be useful to students in other engineering disciplines. Salient Features Provides all the important standard and precise definitions Contains numerous solved examples to help students to grasp the basics Provides hints and explanations for every problem for better understanding Helps build one's own minimal LISP in fewer than 1000 lines of code Familiarizes the students with imperative programming as another way of implementing programs Reinforces the principle of abstraction to encourage students to look for more abstract solutions.
