“A day is coming, when, in the eye of the law, literary property will be as sacred as whisky, or any other of the necessaries of life.” —Mark Twain” Inventors, programmers, writers, and musicians often get the same advice for

In computer science academia, C along with UNIX, and PDP11s, is as unfashionable as can be: the equivalent of other 1970’s relics, like polyester leisure suits and mullets. In 2018 ACM Queue published an essay by David Chisnall called: C
Considering how important “undefined behavior” has become to C semantics and the ISO/IEC JTC1/SC22/WG14 Committee, the lack of any reference to it in the K&R ANSI book is notable and the description in the 1999 C Rationale was quite modest.
The C Standards process over the last few decades has addressed both optimization and pointer type safety largely through a concept called “undefined behavior”. The idea is that instead of positive rules for what compilers and programmers can do, the
This 1998 note by Dennis Ritchie from comp.lang.c (and also here ) is very current since the concept of noalias has definitely crept back into the standard. I have reproduced it verbatim, but lightly formatted for readability. For further reading

This paper is an experiment in presenting programming algorithms as recursive functions, without pseudo-code or genuine code. The algorithms presented are the standard basic sorting algorithms with some computational complexity analysis. The style is that of ordinary working mathematics although
