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.

Using format specifiers for unsigned integers

Unsigned integers include positive integers in several base numbering systems, as well as pointer values. The first example program is unsignedInt.c, and it begins as follows:

#include <stdio.h>
int main( void ) {
int smallInt = 12;
int largeInt = (1024*1024*3)+(1024*2)+512+128+64+32+16+8+4+2+1;
int negativeInt = -smallInt;
unsigned anUnsigned = 130;

// the other code snippets go here.

This code defines smallInt, largeInt, negativeInt, and unsigned int values. These will be used in each snippet that follows. After you type in the program and get it to run, you may want to experiment with different values for each of these variables.
