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.

Exploring the static storage class

Sometimes, it is desirable to allocate memory in such a way that it can hold a value beyond the lifetime of automatic memory variables. An example of this might be a routine that could be called from anywhere within a program that returns a continuously increasing value each time it is called, such as a page number or a unique record identifier. Furthermore, we might want to give such a function a starting value and increment the sequence of numbers from that point. We will see how to do each of these.

Neither of these can be achieved easily with automatic storage classes. For this, there is the static storage class. As with the automatic storage class, it can exist as both internal and external storage.
