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 some analogies in the real world

Real-life analogies for pointers are abundant. We'll explore two analogies to help provide some clarity about them.

In our first analogy, John, Mary, Tom, and Sally each own a different thing that they will give to us when we ask them for it. John owns a book, Mary owns a cat, Tom owns a song, and Sally owns a bicycle. If you want, say, a song, you ask Tom. If you want a bicycle, you ask Sally. If we want something, we godirectlyto the owner of it. That is direct addressing.

Now, say we don't know who each of them is or what they own. Instead, there is someone else we know, say, Sophia, who knows each person and what they own. To get something that we want, we have to go to Sophia, who then goes to the proper person, gets what they own, and gives it to us. Now, to get a book, we go to Sophia, who then goes to John to get the book and gives it to us. To get a cat, we again go to Sophia, who then goes to Mary to...
