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 quick introduction to Bstrlib

Bstrlib is a set of programs that is meant to completely replace the C standard library string handling functions. It provides the following groups of functions:

  • Core C files (one source file and header)
  • Base Unicode support, if needed (two source files and headers)
  • Extra utility functions (one source file and header)
  • A unit/regression test for Bstrlib (one source file)
  • A set of dummy functions to abort the use of unsafe C string functions (one source file and header)

To get the core functionality of Bstrlib, a program onlyneeds to include one header file,bstrlib.h, and onesource file,bstrlib.c, for compilation, along with the other program source files.

Unlike C strings, which are arrays of '\0'-terminated characters, bstring is a structure defined as follows:

struct tagbstring {
  int mlen;            // lower bound of memory allocated for data...
