15 Excellent Free Books to Learn C

7. The GNU C Reference Manual by Trevis Rothwell, James Youngman

The GNU C Reference ManualThe GNU C Reference Manual is a reference for the C programming language and aims to document the 1989 ANSI C standard, the 1999 ISO C standard, and the current state of GNU extensions to standard C.

This manual is strictly a reference, not a tutorial. Its aim is to cover every linguistic construct in GNU C, but not the library functions

The book is not designed for new programmers, and is not an introductory text for C.

Chapters cover:

  • Lexical Elements – describes the lexical elements that make up C source code after preprocessing. These elements are called tokens. There are five types of tokens: keywords, identifiers, constants, operators, and separators
  • Data Types – examines primitive data types, enumerations, unions, structures, arrays, pointers, incomplete types, type qualifiers, storage class specifiers, and renaming types
  • Expressions and Operators – also looks at incrementing / decrementing, arithmetic operators, complex conjugation, comparison operators, logical operators, bit shifting, bitwise local operators, pointer operators, the sizeof operator, type casts, and more
  • Statements – read about labels, expression statements, the if statement, the switch statement, the while statement, the do statement, the for statement, blocks, the null statement, the goto statement, the break statement, the continue statement, the return statement, and the typedef statement
  • Functions – learn about function declarations, function definitions, calling functions, function parameters, variable length parameter lists, calling functions through function pointers, the main function, recursive functions, and more
  • Program Structure and Scope – looks at the big picture
  • A Sample Program – a complete program written in C, consisting of both a C source file and a header file. This program is an expanded version of the quintessential “hello world” program, and serves as an example of how to format and structure C code for use in programs for FSF Project GNU

The book is available under the terms of the GNU Free Documentation License, Version 1.3 or later.

8. Build Your Own Lisp by Daniel Holden

Build Your Own LispLearn the C programming language and at the same time learn how to build your very own programming language, a minimal Lisp, in under 1000 lines of code.

This book is for anyone wanting to learn C, or who has once wondered how to build their own programming language. It is not designed as a first programming language book, as you need some programming experience to make your way through the content.

9. The GNU C Programming Tutorial by Mark Burgess, Ron Hale-Evans

The GNU C Programming TutorialThe GNU C Programming Tutorial introduces the reader to the basic ideas in a logical order. It offers detailed coverage of each of the main elements of the C language and how to program in C, with special emphasis on the GNU/Linux compiler and associated software.

There are chapters devoted to functions, variables and declarations, scope, expressions and operators, parameters, pointers, decisions, loops, arrays, strings, input and output, and much more.

The GNU C Programming Tutorial is released under the GNU Free Documentation License, Version 1.1.
