C Programming - Chapter 8 - The UNIX System Interface

This www.cc4e.com web site is dedicated to learning the "classic" version of the C Programming language from the 1978 book written by Brian Kernighan and Dennis Ritchie. This K&R book places the reader in the middle of the 1970's transition from a hardware-centered computer science to a focus on writing portable and efficient software. C was used to develop operating systems like Unix, Minix, and Linux.

The preface to C Programming by Brian Kernighan and Dennis Ritchie places the C programming language in the context of the other popular programming languages of the 1960's and 1970's FORTRAN, COBOL, Pascal, Algol, and PL/I .  Many concepts like separation of concerns and the use of provided run-time libraries versus language syntax are introduced and described.

Chapter One of C Programming by Brian W. Kernighan and Dennis M. Ritchie gives a broad overview of the scope of the C language while leaving out most of the detailed descriptions.
