Sorry, I went off half-cocked.  That's what happens when you type before
your first cup of coffee.  You're absolutely right, and I stand corrected.
Thanks.
Friends don't let friends type without thinking.

No: "C++" will _not_ understand it either. C++ handles char arrays the same
as C does. C++ does have a string class, which you would use like this:

    string   mystring;
    mystring = "Hello";

Note that 'string' is the data type of 'mystring'.

No: 'string' is an array reference, which is, in most contexts, treated as a
constant pointer (ie: one which cannot be changed). The compiler should
generate an error on the assignment.
