One of the distinguishing features of this text is its deep dive into the Preprocessor, a tool often glossed over in beginner books.

One might ask: "Why read a 30-year-old book when modern C standards (C11, C17, C23) exist?"
The answer lies in the foundations. The topics Kochan and Wood chose are low-level enough that standards have not invalidated them. The way a stack frame works, the way the heap organizes memory, and the way the preprocessor manipulates tokens are the same today as they were in 1991.
Furthermore, modern embedded systems (IoT devices, automotive ECUs) often use C89 or C99 due to compiler constraints. The "Topics" book is an ideal manual for these environments. It teaches you to write robust code without assuming you have a full POSIX implementation.
The original edition (1988) covered “classic” K&R C. The revised edition (1991, sometimes 1995) is the one to find—it updates all examples to ANSI C (C89/C90), which remains the common denominator for embedded systems, legacy codebases, and operating system kernels. Stephen G Kochan- Patrick H Wood Topics in C Programming
Is the book outdated? Parts are:
However, 90% of the content is still gold. The core challenges of C programming—memory management, pointer manipulation, modularity, portability—haven’t changed. In fact, modern C standards (C11, C17) add features but do not invalidate the foundational techniques taught here.
Most books mention #define for constants and macros. Kochan and Wood treat the preprocessor as a programming language in its own right:
You cannot easily buy a new print copy of Topics in C Programming from major retailers. It is out of print. However, used copies circulate on AbeBooks, eBay, and vintage computer book forums. PDF scans are also available in some academic archives (though we encourage supporting legacy works via official channels where possible). One of the distinguishing features of this text
If you find a copy, here is how to use it effectively:
To understand the weight of Topics in C Programming, one must first understand its authors.
Stephen G. Kochan is a prolific author known for his ability to demystify complexity. His earlier work, Programming in C, was a gentle, exhaustive introduction for beginners. Kochan’s strength lies in pedagogy—breaking down syntactic sugar into digestible, logical chunks. He writes like a patient professor who anticipates where students will stumble.
Patrick H. Wood, on the other hand, came from the trenches of systems-level development. Wood was deeply involved with the technical nitty-gritty: pointers to functions, dynamic memory allocation strategies, and the fragile art of portability. Conditional Compilation:
When these two forces combined, they created a hybrid text. Kochan provided the structural clarity, ensuring the reader never felt lost. Wood injected the blood and guts of real-world C—the kind of code that runs in embedded devices, operating system kernels, and database engines. Together, they didn't just teach C; they taught C mastery.
Since Topics in C Programming is out of print (and secondary market copies are rare and expensive), acquiring it may be difficult. However, the spirit of Kochan and Wood lives on. Here is how to apply their methodology to your own learning:
The Stephen G. Kochan–Patrick H. Wood collaboration indirectly influenced the creators of modern C tooling. The emphasis on clean abstraction via opaque pointers and robust error handling via errno patterns became standard in projects like the Apache Portable Runtime (APR) and the Linux kernel style guide.
Wood’s later work on embedded systems and Kochan’s continued authorship (including popular books on Unix Shell Programming) cemented their philosophy: A programmer who understands memory and control flow can master any language.
