Learn C Programming - Second Edition

By: Jeff Szuhay

Overview of this book

The foundation for many modern programming languages such as C++, C#, JavaScript, and Go, C is widely used as a system programming language as well as for embedded systems and high-performance computing. With this book, you'll be able to get up to speed with C in no time. The book takes you through basic programming concepts and shows you how to implement them in the C programming language. Throughout the book, you’ll create and run programs that demonstrate essential C concepts, such as program structure with functions, control structures such as loops and conditional statements, and complex data structures. As you make progress, you’ll get to grips with in-code documentation, testing, and validation methods. This new edition expands upon the use of enumerations, arrays, and additional C features, and provides two working programs based on the code used in the book. What's more, this book uses the method of intentional failure, where you'll develop a working program and then purposely break it to see what happens, thereby learning how to recognize possible mistakes when they happen. By the end of this C programming book, you’ll have developed basic programming skills in C that can be easily applied to other programming languages and have gained a solid foundation for you to build on as a programmer.

Introducing the for()… statement

The for()… statement has the following syntax:

for( counter_initialization ; continuation_expression ; counter_increment ) statement_body

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, 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, the counter_increment expression is evaluated. Then, the process repeats, with the evaluation of continuation_expression. When continuation_expression evaluates to false, the loop ends;...
