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.

Declaring arrays of two dimensions

Just as in declaring a one-dimensional array, [ and ] are used to specify each dimension. array2D is declared using numeric literals for its two dimensions, as follows:

int array2D[4][5];

Using the constants that we already defined, we would declare array2D, as follows:

int array2D[size2D][size1D];

We could also use variables:

int rows = 4;
int cols = 5;

int array2D[rows][cols];

As with any array declaration using variables, the value of the variables may later change, but the array size is fixed and unchangeable after it is declared.
