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.

Expressions and operations

What are expressions? Well, in simple terms, an expression is a way of computing a value. We've seen how to do this with functions and return values. We will now turn to C's basic set of arithmetic operators for addition, subtraction, multiplication, and division, which are common in most programming languages. C adds to this a large number of operations that includes incrementation/decrementation, relational operators, logical operators, and bitwise manipulation. C further extends assignment operations in useful ways. Finally, C includes some unusual operators that are not commonly found in other languages, such as conditional and sequence operators.

The expressions we will explore in this chapter consist of one or more values as variables or constants combined with the help of operators. Expressions can be complete statements; however, just as often, expressions are components of complex statements. Operators work on one or more expressions...
