This site contains the Yacc and Lex grammar for the Pascal programming language. The parsers and lexers generated by the grammer will be in C. They will accept as input a Pascal program.
This is not exactly a grammar of ANSI C++, since it actually accepts a superset of C++ constructs. However, if you're thinking of writing your own grammar, this might serve as a starting point for your own. It is taken from the Working Paper (1996) for the Draft Proposed International Standard for Information Systems--Programming Language C++.
There's nothing like the grammar and source code of an existing world famous compiler, the GNU C/C++ Compiler, to use as a template for your own compiler design. This compiler, and consequently its grammar, actually tries to keep up with the ANSI standards (unlike the popular compiler from a certain well-known OS manufacturer, which only pays lip service to the term "standards compliance").
According to their website, "this grammar has been recovered from IBM's VS-COBOL II Reference Summary" and is supposed to be "fully-tested".
This grammar, in its current incomplete and uncorrected form, was apparently "recovered from IBM's COBOL Language Reference".
Using an automated tool, the grammar given in IBM's OS PL/I V2R3 Language Reference is available from this website. It is apparently still incomplete.
This grammar of the Ada follows the Ada 95 Reference Manual. It is currently incomplete.
