title: How to set C++ language standard in C++ Builder
body: <p>Today we worked on a piece of code that requires either C++14 or C++17.  My colleague used C++Builder for the code editing, and also wanted to try to compile the code piece with it.</p>
  <p>We could not find the setting where one sets the C++ language standard. What we found by googling was that C++builder has a &quot;classic compiler&quot; that supports only parts of C++11 and a &quot;clang-based compiler&quot; that supports up to C++17. We found a check box for enabling/disabling the &quot;classic compiler&quot; in the project settings, but no project setting for selecting the language standard explicitly (to switch between C++14 and C++17). Is there something like that? Where?</p>
  <p>The version that we have is C++Builder 10.2.</p>
  <p>We also tried to explicitly set an additional compiler option -std=c++14 for the clang-based compiler but this option was rejected (&quot;unknown value c++14&quot;).</p>
