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.

Introducing the if()… else… complex statement

if()… else… is a complex statement that can have two forms—a simple form where the if()…part is present, and a complete form where both the if()… and else… parts are present.

In the if()… else… complex statement, either the true path or the false path will be executed. The path that is not taken will be ignored. In the simplest if()… statement where there is no false path, the true path is executed only if the conditional expression is true.

The statement has two syntactical forms, as follows:

  • The simplest form (no false path), as illustrated in the following code snippet:
if( expression )

statement3 /* next statement to be executed */
  • The complete form (both, the true path and false path), as illustrated in the following code snippet:
if( expression...
