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.

Initializing strings

When we declare and initialize a string array, there are a few more possibilities that must be understood. We will explore them now:

  1. We can declare an empty string—that is, a string with no printable characters—as follows:
charstring0[8] = { 0 };

string0 is an array of 8 elements, all of which are initialized to NULL, the nul character, or simply 0.

  1. Next, we can declare a string and initialize the array with individual characters, as follows:
charstring1[8] = { 'h' , 'e' , 'l' , 'l', 'o' , '\0' }; 

When doing this, we must remember to add the nul character, or '\0'. Note that even though the array is declared to have 8 elements, we have onlyinitialized six of them. This method is rather tedious.

  1. Thankfully, the creators of C have given us an easier way to initialize a...
