R.J. Khan - C Programming Language Quickstart Guide: Simplified Guide for Beginners

Programming LanguageQuick Start GuideSimplified Guide for BeginnersBy:R.J. KHAN

Are you looking for a simple, complete and quick reference for programming in C? If yes, youll find this book more useful than any other book out there. The book presents the general-purpose language, step by step. The book is written following a programmers approach and is therefore ideal for using as a quick guide and reference. The book is highly recommended for students as their first or second programming course. It covers all the basic concepts of programming in detail like Operators, Functions, Decision making statements, Pointers, Arrays and Strings.

The best thing about the book is the Source code along with output at the initial stages of book. Other than students, the book is pretty helpful for professionals as well since it has a thorough and detailed indexing of topics in each chapter. The book allows the audience to be selective by reducing the inter-connectivity in the topics. We start with an overview of whole language, which involves brief history, basic features of C, comparison and contrast with other languages. Then we move on to familiarizing the readers with C programs and syntax. We discuss the important components of syntax individually and in detail.

This section has source code in it, which helps building the interest, and learning of the audience. We study in detail about the Functions in C. The book discusses the built in functions as well as describes the rules and basics of writing your own functions. The chapter also includes programming examples. Arrays, pointers and Strings are strong points of C language and hence are discussed separately in one chapter. The topics are closely related, hence comparisons and contrasts are worth the discussion.

We have an entire chapter dedicated to Binary Trees because of their importance. We discussed Abstract Data types as well as studied the examples of Stacks, Queues and Linked lists. The book illustrates the general purpose use of programming language C, detailed documentation of features provided by C, the working source code, along with comparison between object oriented language, C++. The differences between ANSI C and traditional language C are elaborated in detail as well. R.J. Khan Copyright 2015 by R.J.

We start with a brief background and discuss pros and cons of the general-purpose language. After that, a series of programs follows, and the elements of each program are carefully, line-by-line explained. We emphasize on how to use the basic input/output functions of C. As we discuss in detail the similarities between C and C++, you can fairly assume that the programs written are syntactically correct for both the languages and the concepts elaborated are also common.

Of course, the C++ programmer has more capabilities using the object oriented programming concepts. We recommend that everyone reads this chapter out so that they know the basics about C and programming in C. Everyone should read this chapter even if they dont understand everything because everything is explained in detail later on, in the book but the introduction in this chapter is important. 1.1 Background: C is a procedural programming language that was originally designed by Dennis Ritchie at Bell in 1972. UNIX operating system used it as the systems language. C was designed to overcome the shortcomings of a programming language B, which was designed by K.

Thompson while working on initial versions of UNIX. B was a programming language based on BCPL, a type less systems programming language, developed by Martin Richards in 1967. Its basic data type was the machine word, and it made heavy use of pointers and address arithmetic. It is completely different from traditional structural programming, which involved use of typed commands. Although C initially evolved from Band BCPL, but it included typing. By the early 1980s, the language has transformed itself into what it looks like today, commonly known as the traditional C.
