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.

Summary

In this chapter, we explored the elements of strings—characters. In particular, we explored the details of ASCII characters and how they are organized by developing a program in several iterations to print out a complete ASCII table. We also explored some simple operations on characters using the C standard library.

From there, we saw how C strings are special arrays made up of characters and a terminating NUL character. The NUL terminating character is something to which we must pay particular attention to when we create and manipulate strings. We explored how strings and string operations are built on other existing C concepts of arrays and pointers. We explored the difference between string literals, which are constant and modifiable strings. We further saw how to pass both of them to functions. All of these string concepts have been employed in the program we've developed to print the full 7-bit ASCII character set table. Finally, we introduced...
