    __cplusplus number

    I'm involved in a project written for gcc (although I build with VS2019). Recently, someone added a section like this:-

    # if (defined(__cplusplus) &&  __cplusplus >= 201709L)
          // Some functionality
    # emdif
    Even in VS2019, Intellisense removes that code section - so I did some digging and realised that in Properties->General my C++ Language Standard was set to the default (ISO C++14 Standard). So I tried the various alternatives but nothing makes that section appear. Is there some other setting I need to change? I'm assuming that for VS2019 the value of __cplusplus should be higher than 201709

    [Edit...] FWIW if I add the line:- long my_test = __cplusplus; to some module, the returned value seems to be 199711
