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 loop equivalency

After having typed in both versions of each loop and run them, you may have begun to see some similarities between each of the looping statements. In fact, for counter-controlled looping, each of them is readily interchangeable.

To illustrate, let's examine each counter-controlled loop by comparing each of their essential parts.

The counter-controlled while()… loop has the following syntax:

while( continuation_expression ) {

Notice that both counter initialization and counter increments have been added to the basic syntax of the while()… loop and that they are somewhat scattered about.

The counter-controlled for()… loop has the following syntax:

for( counter_initialization ; continuation_expression ; counter_increment ) 

It would be perfectly logical to assume that the for()… loop is...
