I have found from other answers that in my Eclipse Mars CDT I can setup C++11 dialect using:
Project -> Properties -> C/C++ Build -> Settings -> Tool Settings -> GCC C++ Compiler -> Dialect -> ISO C++11 (from drop down list)
and C++11 syntax highlighting using:
Project -> Properties -> C/C++ General -> Preprocessor Include Paths, Macros etc. -> Entries -> GNU C++ -> Add.. (for CDT User Setting Entries) -> Preprocessor Macro: __cplusplus=201103L
Questrion:
How to save those properties as default configuration so that when I create new C++ project I will have them already set?
