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.

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 executing the function body, it returns to the place of the function call and continues execution. 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 can 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. However, when reworking their results in more awkward code, the complex conditional expression should be thoroughly commented. Careful consideration should be given to the...
