Digital Mars C++ is a free C++ compiler for DOS and Windows.

Originally a C compiler created by Datalight, it was sold to Zortech, who then added a C++ compiler, calling the result '''Zortech C++'''. Symantec purchased Zortech specifically to get ownership of these compilers, which were eventually acquired by Digital Mars (which is more well-known for creating the D programming language).
