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 2

In a terminal/console with a Unix shell (such as csh, tsh, bash, and so on), do the following:

  1. Create a simple program—for example,hello.c.
  2. Add the header file you want to find, and save it.
  3. In a bash command shell, execute the following:
          cc -H hello.c 2>&1 | grep '^\.\ '

This command, which looks like a lot of gobbledegook, is doing the following:

  1. It invokes the compiler with the -H option. The list of header files is sent to stderr.
  2. 2>&1 redirects stderr to stdout.
  3. stdout is then redirected via a pipe (|) to grep, a regular expression parser.
  4. grep is told to search the beginning of each line for <period><space>:
    • '…' is the search string.
    • ^ indicates the beginning of a line.
    • \. is a period (this is important as a dot (.) alone has special meaning in grep).
    • \ is a space (this is important...
