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.

A few simple examples

These examples are very, very simple and are meant to give you a feel for what using Bstrlib is like. The examples provided on the SourceForge website are quite advanced string handling examples. They are extremely useful and well worth studying.

Our firstBstrlib example will be the Hello, world! program, as follows:

#include <stdio.h>
#include "bstrlib.h"

int main( void ){
bstring b = bfromcstr ("Hello, World!");
puts( (char*)b->data );

This program, bstr_hello.c, creates a bstring from a C string and then prints it using puts(). To compile this program, be sure that the bstrlib.h and bstrlib.cfilesare in the same directory as this program. Then, enter the following command:

          cc bstrlib.c bstr_hello.c -o bstr_hello -Wall -Werror -std=c18

In our next example, we will split a string into multiple strings based on a delimiter and then print them. We can do this with the C standard...
