syntax - Occurrences of question mark in C code -

Am I doing a simple program in which the events of the Ternary operator should be counted ?: In the C source code. And I'm trying to simplify it as much as possible. So I have filtered these things with the source code:

1. string literals ""
2. character constants ''
3. sequence view ?? =,?
4. Comments
5. Macros

   And now I'm only counting incidents of questions.

   So my question is whether there is any other symbol, operator or any other problem that can cause problems - '' '?'?

   Suppose source syntax is valid.

   I think you meet all the places where question marks are introduced and therefore all possible False positives (for triangle session) are eliminated. Maybe you've ended too much: maybe you want to count those "": "" which are offered by macros; You do not count those people, do you intend it? If it is, then you have done it.
