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.

Compound assignment operators

As we have already seen, expressions can be combined in many ways to form compound expressions. There are some compound expressions that recur so often that C has a set of operators that make them shorter. In each case, the result is formed by taking the variable on the left of the operator, performing the operation on it with the value of the expression on the right, and assigning it back to the variable on the left.

Compound operations are of the form variable operator= expression.

The most common of these is incrementation with an assignment:

counter = counter + 1;

With the += compound operator, this just becomes the following:

counter += 1 ;

The full set of compound operators is as follows:

  • += assignment with addition to a variable
  • -= assignment with subtraction to a variable
  • *= assignment with multiplication to a variable
  • /= assignment with division...
