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.

Chapter 6: Exploring Conditional Program Flow

Not only do the values of variables change when a program runs but the flow of execution can also change through a program. The order of statement execution can be altered depending upon the results of conditional expressions. In a conditional program flow, there is one mandatory branch and one optional branch. If the condition is met, the first branch, or path, will be taken; if not, the second path will be taken.

We can illustrate such a branching with the following simple example:

Is today Saturday?

If so, do the laundry.

Else, go for a walk.

In this conditional statement, we are instructed to do the laundry if today is Saturday. For the remaining days that are not Saturday, we are instructed to go for a walk.

This is a simple conditional statement; it has a single conditional expression, a single mandatory branch, and a single optional branch.

The following topics will be covered in this chapter:
