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 for()… statement

The for()… statement has the following syntax:

for( counter_initialization ; continuation_expression ; counter_increment ) 

The for()… statement consists of a three-part control expression and a statement body. The control expression is made up of a counter_initialization expression, a continuation_expression, and a counter_increment expression, where a semicolon separates each part of an expression. Each one has a well-defined purpose. Their positions cannot be interchanged.

Upon executing the for()… statement, the counter_initialization expression is evaluated. This is performed only once. Then, continuation_expression is evaluated. If its result is true, the statement_body is executed. At the end of statement_body, thecounter_incrementexpression is evaluated. Then, the process repeats, with the evaluation of continuation_expression. When continuation_expression evaluates to...
