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.

Moving on to two-dimensional arrays

A two-dimensional array can be conceptualized either as an array of arrays (one-dimensional) or as a matrix consisting of rows and columns. For our discussion, we'll consider a two-dimensional array, named array2D, either as an array of four arrays of five one-dimensional elements or as a matrix of four rows and five columns. Both conceptualizations are equivalent.

In terms of the real world, there are many examples of two-dimensional arrays—hotel mail slots, windows on the side of a modern skyscraper, any video display that has a matrix of pixels, the periodic table of elements, a spreadsheet of multiple rows and columns, the selection of snacks in a vending machine, and a baseball innings scoreboard, to name a few. A two-dimensional array in C, therefore, is a useful tool for modeling many real-world matrices or grids.

If we consider array2D as an array of arrays, we have an array of four groups of a defined type...
