Setting a String to NULL in C++?

[perseus]

I have a string, say GLOBAL, that I use a lot
in a CPP-program. From time to time this string needs to
be set to the NULL-string, i.e., empty itself of its content.
How do we do it?
Thanks!

To empty a string call the 'clear' member function. There
is no 'setting to NULL' because it's not a pointer.

Victor,

Can I call this function in BC5 with Windows XP?
What .h file is needed here?
An example would be just great!
Thanks!

Any C++ compliant compiler can do this regardless
of platform.

An example would be just great!

string foo("Bar need's a good C++ book");

// examines include dir's more often

foo.clear();

It should, but since your compiler is obviously broken, how about the
obvious

foo = "";

It has nothing to do with compiler. It is unimlemented in STL you are
using.

BTW: I use STL from SGI on linux and have same "problem" which I solve
in same way as John.
