What was the rationale for dropping the .h suffix for standard headers (e.g., <iostream> vs <iostream.h>)? Just curious. (I already asked in comp.std.c++, but the moderators there work like molasses -- my post from yesterday still hasn't appeared.)

You'd have to ask the standards committee members to be sure, but I suspect at least part of the reason is to reduce the possiblity of conflicts with the inherited C headers (e.g <string.h> and <string>, each of which declares completely different things.) Quote: (I already asked in comp.std.c++, but the moderators there work like molasses -- my post from yesterday still hasn't appeared.) Moderated groups are 'slow' by nature. I don't think it's legitmate to call the moderators 'slow as molasses', as their job is an unpaid volunteer activity. I'm sure they have their own lives to deal with too. -Mike Back to top Jeff Flinn Guest Posted: Thu Dec 30, 2004 4:46 pm    Post subject: Re: Why was the .h dropped in std headers?

Prehaps it's your news server that's slow as molasses. Jeff Back to top Victor Bazarov Guest Posted: Thu Dec 30, 2004 4:50 pm    Post subject: Re: Why was the .h dropped in std headers?

Or was it somebody else's question? I saw 4 replies, IIRC, one from Andrew Koenig.

Because there was a de facto standard that most programmers were using and the names of headers was part of it. C++98 took these well-known names, modified them a bit and tried to make their content (if only the names used, such as cout and cin) as similar as possible to what people were used to. Finally, to avoid having two <iostream.h> on the same machine working differently, the .h was dropped. Stroustrup also says the .h is redundant because #include <> specifies a header, but that's a bit far fetched.

I guess those volunteer moderators are faster than I gave them credit for. :) Back to top Derek Guest Posted: Thu Dec 30, 2004 5:11 pm    Post subject: Re: Why was the .h dropped in std headers?

First, it's my news service that's slow, not the moderators -- apparently I received replies yesterday, though I still can't see them through my usual means. Second, I wasn't knocking the moderators and I know they have lives. I only made that comment as a preemptive strike against the "ask in comp.std.c++" replies that I was expecting. :) Back to top Julián Albo Guest Posted: Thu Dec 30, 2004 6:06 pm    Post subject: Re: Why was the .h dropped in std headers?

There was no urgency except my own curiosity.
