How to deal with noexcept in Visual Studio

Question

I\'m trying to create a custom exception that derives from std::exception and overrides what(). At first, I wrote it like this:

class U         


        

Answer 1

Use a macro

#ifndef _MSC_VER
#define NOEXCEPT noexcept
#else
#define NOEXCEPT
#endif

And then define the function as

virtual const char* what() const NOEXCEPT override

You could also modify that to allow noexcept on later versions of VS by checking the value of _MSC_VER; for VS2012 the value is 1600.
