When you refer to CString are you talking about a class of some kind or are
you mixing up the C++ class String with a c "style" string?

A c style string is in fact a null terminated string, and when you write
"Hello World!" (note no need for \0) you are just declaring a null
terminated string.

If you are useing the C++ String class then to use it as a C string you have
to use it's member function c_str(); which returns a pointer to a temporary
c style string. Note that you shouldn't try to modify the string through
this function.
