The C++ language cannot be described exactly in terms of precedence rules for operators. Instead, grammar rules are used. Some of those grammar rules imply relationships which are equivalent to those described by precedence rules, but others are impossible to describe that way. The ?: operator, in particular, causes problems simply because it's the only ternary operator. It's been argued that '?expression:' can be thought of as being a binary operator, and that when considered as such, has effectively equal precedence with assignment operators. --- [ comp.std.c++ is moderated.
