I am reading the classic book on C - The C Programming LanguageBook by Brian Kernighan and Dennis Ritchie. The preface of the book saysAll examples have been tested directly from the text, which is in machine-readable form. What does this mean?
What does All examples have been tested directly from the text, which is in machine-readable form mean?
c
(just a guess)Probably that every code example has been indeed tested on a system with a C compiler, and pretty-printed in the book (perhaps using troff or whatever document formatter was used by K&R) by some automatic tool (I don't know what tool was used by K&R. Today, you'll use e.g. vgrind or pygments or LaTeX's listings package, or some other pretty-printer). So there cannot be typos while converting C code to paper (e.g. as if the C code has been manually copied and typeset)
