Learn C Programming - Second Edition

By: Jeff Szuhay

Overview of this book

The foundation for many modern programming languages such as C++, C#, JavaScript, and Go, C is widely used as a system programming language as well as for embedded systems and high-performance computing. With this book, you'll be able to get up to speed with C in no time. The book takes you through basic programming concepts and shows you how to implement them in the C programming language. Throughout the book, you’ll create and run programs that demonstrate essential C concepts, such as program structure with functions, control structures such as loops and conditional statements, and complex data structures. As you make progress, you’ll get to grips with in-code documentation, testing, and validation methods. This new edition expands upon the use of enumerations, arrays, and additional C features, and provides two working programs based on the code used in the book. What's more, this book uses the method of intentional failure, where you'll develop a working program and then purposely break it to see what happens, thereby learning how to recognize possible mistakes when they happen. By the end of this C programming book, you’ll have developed basic programming skills in C that can be easily applied to other programming languages and have gained a solid foundation for you to build on 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*OE头"
// (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...
