For entertaining language freaks like me, I have compiled an HTML page with all syntax/grammar productions for C++98 and C++11. All language elements are linked so that one can navigate forth and back in the EBNF productions.
The full file can be found here[^].
It contains a list of:
- Syntax productions
- Language variants (C++98 only and C++11 only items)
- Full syntax production cross reference
The variants[^] section might be of special interest.
