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.

Manipulating multi-dimensional arrays – loops within loops

There are many ways in which to use loops to access elements within multi-dimensional arrays. The best way, however, is to use nested for()… loops. In a nested loop, the outermost loop contains one or more loops within it, nested such that the outer loop completely contains the inner loop. When using nested loops, the outermost loop manipulates the index of the highest-order dimension, while the innermost loop manipulates the index of the lowest-order dimension. We will explore two- and three-dimensional looping. It is then simple to extend the nested loops to as many as are needed for an array with more than three dimensions.

When nesting loops, it is a common convention to use variables named i, j, k, and so on to hold the values of the array offsets, with i being the first-order dimensional offset, j being the second-order dimensional offset, k being the third-order dimensional offset, and so on...
