How to change c++ version in RAD 11?  want to change the c++ version from c++ 11 to something newer than this.

In RAD Studio 11 (and since 10.3), only the Windows clang compilers support C++14 and C++17, the rest of the clang compilers support only C++11.  See Modern C++ Features Supported by RAD Studio Clang-enhanced C++ Compilers for details.

 

You should not have to do anything extra to enable C++17 by default when compiling for Windows.  However, if you want to specify a specific standard version, you can do so manually in the project options via "C++ Compiler > Advanced > Other options  > Additional options to pass to the compiler", eg:
