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.

Printing a structure of structures – reusing functions

Let's create a function to print the contents of the hand. This function will use a function that we will create to print the structures it contains. In this way, the minimum amount of code is used since printing an individual card exists in only one function. The following function takes our struct Hand as an input parameter, determines which card we are dealing with, and calls printCard() with that card as a parameter, as follows:

void printHand( struct Hand h )  {
for( int i = 1; i < h.cardsDealt+1 ; i++ ) { // 1..5
struct Card c;
switch( i ){
case 1: c = h.c1; break;
case 2: c = h.c2; break;
case 3: c = h.c3; break;
case 4: c = h.c4; break;
case 5: c = h.c5; break;
default:return; break;
printCard( c );

In the preceding printHand() function, we iterate over the number of cards in our hand. At each iteration, we figure out which card we are looking at and copy it to a temporary variable so...
