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 structures

The structure type allows us to specify a group of related variables, each representing a facet, or component, of the thing being modeled. There may be just a few components in the modeled thing; more often than not, there are many components. Each component can be of any intrinsic C data type (integer, real, Boolean, char, complex, and so on) or any previously defined custom type. The components in a structure do not have to be of the same type. Therein lies the power of the structure – it allows us to group various aspects of the thing into a single custom data type; in this case, a C structure. We can then use that data type much like we use any other data type.

The syntax for defining a structured type is as follows:

struct name{
type componentName1;
type componentName2;
… ;
type componentNameN;
};

The type consists of the two words, struct and name. The components of the structure are contained within { and ...
