I would like to know why the Visual C++ compiler gets me an warning/error if I use the following code:

#pragma message( "You have " _MSC_FULL_VER )

Here is what I get:

error C2220: warning treated as error - no 'object' file generated
warning C4081: expected ':'; found ')'

The problem reproduces for _MSC_FULL_VER or _MSV_VER but not if I try to use others like __FILE__ or __DATE__.

These macros are defined, they are documented on msdn

Can you write preprocessor directives to return you a std::string or char*? For example: In case of integers: #define square(x) (x*x) int main() { int x = square(5); } I'm looking to do the same but with strings like a switch-case pattern. if pass 1 it should return "One" and 2 for "Two" so… >>> More
