Initialization of data members inside a class

[Joe Bentley]

Is it permissible to initialize non-static data members inside a class,
like so?

class whatever
{
int x = 9;
const int y = 10;
...
};

If so, is there a reference in the "standard" that grants this
permission, and when did this syntax come about?

Thanks

Assuming that
http://en.cppreference.com/w/cpp/language/class#Member_specification
is consistent with the standard, I'd say yes.

Yes

This was introduced in C++11.

See <http://en.cppreference.com/w/cpp/language/data_members> for C++11
and C++14 specific discussion on member initialization.
