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.

Understanding underflow NaN

Underflow occurs when the result of an arithmetic operation is smaller than the smallest value that can be represented by the type specified.

For integers, this would mean either a number less than 0 if the integer is unsigned or a very large negative number if the integer is signed (for instance, -2 is smaller than -1).

For real numbers, this would be a number very, very close to zero (that is, an extremely small fractional part), resulting from the division of an extremely small number by a very large number, or the multiplication of two extremely small numbers.
