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.

Performing operations on structures – functions

Except for assignment, there are no intrinsic operations for structures. To perform any operation on a single structure or with two structures, a function must be written to perform the desired operation.

For example, earlier, we mentioned a function that can be used to compare two structures for equality. This must be done component by component, as follows:

bool isEqual( struct Card c1 , struct Card c2 )  {
if( c1.suit != c2.suit ) return false;
if( c1.face != c2.face ) return false;
return true;

Notice that we did not compare every component of struct Card in this function. We'd only have to do that for absolute comparison and when we need to compare each and every component of both structures. This just isn't necessary for our card example.

Does it make sense to perform any or all mathematic operations on two structures? In general, no, but this answer is completely dependent on...
