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.

Revisiting one-dimensional arrays

An array of one dimension is a block, or contiguous grouping, of a specified data type accessed via a basename; each element is then accessed via an offset of that basename.

A one-dimensional array may be called a vectorin some domains, while in others it may be referred to as alinear array. To review what we covered in the last chapter, we will use a one-dimensional array as the basis for our discussion, as follows:

int array1D[5] = { 1 , 2 , 3 , 4 , 5 };

Here, array1D has five integers, initialized to the values of 1 through 5 for the values at the zeroth through fourth offsets. array1D is a block of five integers; they are contiguous (or side-by-side) so that the block takes up 5 * sizeof(int) bytes of memory. The array has five elements, with offsets from the base to each element in the range of 0..4. This linear array can be represented vertically, as follows:

Alternatively, it...
