Oh, come on guys...
Okay, I admit that my choice of words was a bit inauspicious.
What I meant to say is that a valid C program is also (at least most of the time) a valid C program
But, but, a valid C program is always a valid C program *ducks and covers*

The essence of his post was "With a few minor changes, every valid C program is also a valid C++ program". Can you think of any major changes that would need to be applied to a C89 program (small syntax changes, and variable renaming, are minor) for it to be compiled by a standard C++ compiler?

That is a fair enough assertion, although I would point out that C89 is no longer standard C as it has been superseded by the C99 standard (and relevant amendments since then).

I am not sure whether there is a standard which specifies which of the standards is The Standard, quasi a standard standard. A valid C89 program is and always will be a valid C89 program. A valid C++2003 program will always be a valid C++2003 program, and it's not like it will magically become invalid by the rise of a new standard.
Quote:Original post by CromulentCertainly—there is currently a C89 standard, a C99 standard, and the expression "standard C" refers to the C99 version by default (and a standard C89 program that does not respect C99 requirements cannot claim to be a standard C program anymore).

On the other hand, this discussion is not so much about standard C as it is about the version of the C language used in the "Game Programming all in one" book—which, from my recollections and the 2002 publishing date, seems to be C89.
