I'm going to assume you mean "cast" in the various places where
you wrote "case" -- this sort of carelessness, especially where
both words are technical words, makes it difficult to help.

Anyway, to get to the point, you cannot compile C correctly with
a C++ compiler.  They are different languages and have different
rules.  There is legal C code which is not legal C++; and there
is legal C++ code which is not legal C.  And there are things
that, although legal in both languages, do not have the same
meaning.  C and C++ have very different requirements for casts.

This is a C list.  You have been given C answers.  If you are
trying to write C++, you need another list.
