Learn C Programming

By: Jeff Szuhay

Overview of this book

C is a powerful general-purpose programming language that is excellent for beginners to learn. This book will introduce you to computer programming and software development using C. If you're an experienced developer, this book will help you to become familiar with the C programming language. This C programming book takes you through basic programming concepts and shows you how to implement them in C. Throughout the book, you'll create and run programs that make use of one or more C concepts, such as program structure with functions, data types, and conditional statements. You'll also see how to use looping and iteration, arrays, pointers, and strings. As you make progress, you'll cover code documentation, testing and validation methods, basic input/output, and how to write complete programs in C. By the end of the book, you'll have developed basic programming skills in C, that you can apply to other programming languages and will develop a solid foundation for you to advance as a programmer.

Introducing operations on numbers

The basic arithmetic operators on numbers are addition (+), subtraction (-), multiplication (*), and division (/). They are binary operations as they work on one pair of expressions at a time. They work largely as you would expect them to for both integers (whole numbers) and real numbers. Division for two real numbers results in a real number. Division for two whole numbers also results in a whole number; any possible fraction part is discarded. There is also the modulo operator (%) that will provide the integer remainder of the division of two integers.

For example, 12.0 / 5.0 (two real numbers) evaluates to 2.5, whereas 12 / 5 (two integers) evaluates to 2. If we were working only with integers and we needed the remainder of 12 / 5, we would use the remainder operator, %. Thus, 12 % 5 evaluates to another integer, 2.

Many languages have an exponent operator. C does not. To raise an expression to a power, standard C provides...
