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.

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. We will explore...
