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 unsigned integers in different bases

In the first code snippet, values in various base numbering systems are printed—these are the octal (base-8), decimal (base-10), and hexadecimal (base-16) formats. Each of these values is printed in a minimum field width of 12 characters. The numbers are not truncated. If the converted number is longer than the minimum field, it simply spills over the minimum field width:

 printf( " Unsigned Printf \n" );
printf( " Base Base-8 Base-10 Base-16 BASE-16\n" );
printf( " Name octal unsigned hexadeximal HEXIDECIMAL\n" );
printf( " Specifier %%12o %%12u %%12x %%12X \n" );
printf( " [%12o] [%12u] [%12x] [%12X]\n" ,
smallInt , smallInt , smallInt , smallInt );
printf( " [%12o] [%12u] [%12x] [%12X]\n\n" ,
largeInt , largeInt , largeInt , largeInt );
printf( " [%12o] [%12u] [%12x] [%12X]\n\n" ,
anUnsigned , anUnsigned , anUnsigned , anUnsigned );
