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 conditional expressions

We have seen how execution progresses from one statement to the next with simple statements. We have also seen how program execution can be diverted or redirected via a function call, after which it returns to the same place. We are now going to see how the flow of execution can change and how statements can be executed or skipped with some of C's complex statements.

Execution flow will be determined by the result of evaluating conditional expressions, which we learned about in the previous chapter. Conditional expressions may be either simple or complex. Complex conditional statements should be clear and unambiguous. If they cannot be made clear and unambiguous, they should be reworked to be less complex. When reworking them results in more awkward code, the complex conditional expression should, however, be thoroughly commented. Careful consideration should be given to the valid inputs and expected results of the conditional...
