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.

Understanding structures

It would be extremely easy for C programmers if the world were simply made up of objects that were only numbers or names. Imagine if everyone were expressed as only a name or a series of numbers but nothing else. An automobile Vehicle Identification Number (VIN) precisely describes various attributes of that car and uniquely identifies it. On the other hand, humans are far more complex than automobiles. Perhaps the world would be a very uninteresting place.

For C programs to solve real-world problems, they have to be able to model real-world complex objects. C allows various aspects of real-world objects to be abstracted and modeled via C structures. In the previous chapter, in a very basic way, we explored two such objects – playing cards and two-dimensional shapes. Did we explore every aspect of them? No.

In fact, we barely scratched the surface. For playing cards, we need to be able to describe all 52 cards in a deck uniquely...
