I have a copy of C++ 1998 that I bought some time ago. The language has changed pretty dramatically since then.

The drafts have often been a decent informal ‘go-to’ option but the posted draft for C++ 2017 has a comment on the first page that suggests it is known to be no only poorly formatted but wrong in places.

While the standard isn’t the place to go for day to day reference it is very nice to have the authoritative document around to resolve some issues (and asking what the compiler you’re using at the moment does in not an acceptable answer…ever).

The ISO Standard C++ page has a pointer to the main ISO/IEC 14882:2017 Programming languages — C++ page but the buy button there is denominated in ‘CHF’ (swiss francs). The ANSI web store has it for $232.00 which is a bit steep (substantially more than I paid for the 14882:1998 back when) but may be worth the investment. Budget will tell I guess…
