I tend to use C++ whenever I strongly care about data representation
(which is admittedly rarely.) You can use C for that; I just prefer C
to C++ for almost everything.
The only other thing that would almost certainly lead me to using C++ is
if I needed to use to a C++ library. C++ is extremely difficult to

This is actually one of the first things I wrote in Haskell. It's not
even much of a compiler but mostly just filling in the blanks of some
So I could write:
fac 0 = 1
fac n = n * fac (n - 1)
and get output akin to the example on wikipedia.
