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.

Extracting Card structures and functions

As we extract this file, we will be going through carddeck.c to find the relevant bits. Take the following steps:

  1. Create and open the card.h header file, and put in the following new lines:
#ifndef _CARD_H_
#define _CARD_H_


This is our starting point for this header file. We use the macro directives, as explained earlier, to ensure that anything in this file is only preprocessed once. The _CARD_H_macro is used nowhere else in the program but in this single header file. Everything else that we put in this file will be after #define _CARD_H_ and before #endif.
Next, we would normally add the necessary header files. We will save this for later when we finish the dealer.c and dealer.h files.

  1. In carddeck.c, you now should see a number of const int definitions. The only ones of these that pertain to the Card structure are kCardsInSuit, kWildCard, and kNotWildCard. Rather than...
