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 11: Working with Arrays

We have already seen how a structure is a grouping of one or more components that can each be of different data types. Often, we need a grouping that consists of the same type; this is called an array. An array is a collection of multiple occurrences of the same data type grouped together under a single name. Each element of the array is accessed via its base name and an offset of that base. Arrays have many uses, from organizing homogenous data types to providing the basis for strings, or arrays of characters.

Before we can learn about some of the wide uses of arrays, we need to explore the basics of declaring and manipulating arrays.

The following topics will be covered in this chapter:

  • Declaring an array of values
  • Initializing an array in several ways
  • Understanding variable-length arrays
  • Accessing each element of an array
  • Understanding zero-based array indexing
  • Assigning and manipulating elements of an array
  • ...
