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.

Ranges of values

Let's extend this program to provide the ranges for each data type. While we could compute these values ourselves, they are defined in two header files—limits.h for integer limits and float.h for real number limits. To implement this, we add another function prototype, add a call to that function from within main(), and then define the function to print out the ranges. In the printRanges() function, we use the fixed-width types to avoid variations from system to system.

Let's add another function. In the following code, the additional include directives and function prototype are highlighted:

#include <stdio.h>
#include <stdint.h>
#include <stdbool.h>
#include <limits.h>
#include <float.h>

// function prototypes
void printSizes( void );
void printRanges( void );

int main( void ) {
Now, having printRanges() prototypes, let's add its definition. The printSizes(...
