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.

Method 3

This one is the simplest of all if you have the locateprogramon your system.

In your terminal/console, enter the following command:

          locate <filename.h>

You might also get a lot of output from this since your system might have many versions of these header files.

Method 2 is best because it tells you exactly which header file the compiler is using.

Once you have found the function you want to know more about in one of these files, you can then use the Unix man command to read about it on your system. To do so, enter the following into a terminal/console:

          man 3 <function>

This tells man to look in section 3 for the given function. Section 3 is where C functions are described.

Alternatively, you could try the following:

          man 7 <topic>

Section 7 is where general topics are described. There is a lot of information there...
