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.

Introducing statements and blocks

Before we begin to explore the details of statements, let's return to the various uses of punctuation that we encountered in our Hello, world! program. Here is the program for reference; comments have been removed so that we can concentrate on the details of the code itself:

#include<stdio.h>
int main() {
printf( "Hello, world!\n" );
return 0;
}

At first, I'd like to draw your attention to the paired punctuation—the punctuation that occurs with a beginning mark and a very similar ending mark. Going through it line by line, we see the following pairs—< and >, ( and ) (which occur twice), { and }, and finally, " and ". We also see some other punctuation that may or not be familiar to you. These are #, ., ;, \, <space>, and <newline>. These are punctuation marks that are significant in the C language.

When we look closely at our "Hello, world!\n&quot...
