  • Initialization of data members inside a class

    From Joe Bentley@21:1/5 to All on Sun Feb 21 13:20:11 2016
    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.

    Joe Bentley <[email protected]> spake the secret code <[email protected]> thusly:

    {

    Yes

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

    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.
