One aspect of C++ is that all standard functions of C are called
in the same way. A large part of programs consists of stringing
API calls together. Those require little work to upgrade to
C++. So from a practical point of view this is very much true.

Even if it is overhyped, the C++ compiler vendors certainly tried
to make it happen.
