I am looking for a comfortable and free development environment for C ++ for Mac OS X. Tell me, who knows.
Qt Creator, naturally. At the moment, this is the best IDE for C ++ for UNIX-shaped platforms. And since it exists for Mac OS X, the answer is obvious.
C ++ So much old language and so much C that programs are written in them either in Vim or Emacs.
But seriously, for now the free cLion is in the piggy bank :)
