I'm working with eclipse and I can choose the language standard and/or other dialect flags. When I want to work with the latest language standard, do I need to declare as shown in the image or leave the language standard blank and just define c++11, or the other way around, just define the language standard c++1y and leave the flags empty?

  • language flags depend on your compiler. So find out your compiler version - then go to its documentation and find which -std values are supportd by this version and decide how you'll be able to select specific standard

  • C++11 isn't exactly the latest standard, so I wouldn't select that.

  • Eclipse isn't a compiler. What does your compiler support?

According to Options Controlling C Dialect -std=c++1y is just a deprecated alias to -std=c++14, not to -std=c++11. Even though Eclipse offered a proper alternative option -std=c++0x, it is also deprecated, so you better leave language standard blank and set -std=c++11 among flags.
