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 UTF-to-Unicode example

To give you an idea of what it is like to convert between Unicode and UTF-8, consider the following program:

#include <stdio.h>
#include <locale.h>
#include <stdlib.h>
#include <stdio.h>

int main(void){
wchar_t ucs2[5] = {0};

if( !setlocale( LC_ALL , "en_AU.UTF-8" ) ){
printf( "Unable to set locale to Australian English in UTF-8\n" );
exit( 1 );
// The UTF-8 representation of string "æ°´è°ƒæ*Œå¤´"
// (four Chinese characters pronounced shui3 diao4 ge1 tou2) */
char utf8[] = "\xE6\xB0\xB4\xE8\xB0\x83\xE6\xAD\x8C\xE5\xA4\xB4" ;

mbstowcs( ucs2 , utf8 , sizeof(ucs2) / sizeof(*ucs2) );

printf( "UTF-8: " );
for( char *p = utf8 ; *p ; p++ )
printf( "%02X ", (unsigned)(unsigned char)*p );
printf( "\n" );
printf( "Unicode: " );
for( wchar_t *p = ucs2 ; *p ; p++ )
printf( "U+%04lX ", (unsigned long) *p ...
