why i can't declare my character string as
(char*) care=0;
and what is the mearning of
char& *care ? because i would like to define a pointer to char type that also is a reference.
thank you

Well, the "(char*)" is not declaration. It's a casting operator.Quote:

It's part of the C standard (and hence works in C++, but there are other ways to cast in C++).
i think it is atype definition and the compiler doesn't allow it to define like that
because
char a;
char*a;
only differentiates by an *
so i mean to comprehend why a pair of parentheses make such a difference to the compiler, how ?
Because that's what compilers do? I don't understand what you are asking. Maybe you should back up a bit. What are you trying to do?
Because that's how the language works.Quote:

You can declare char* a = 0 if you like.
what does "back up a bit" really mean ?Quote:

ok, i won't lengthen this thread.
I'm not trying to be deliberately obtuse, but I can't figure out what it is that you are asking? I thought a little background in your overall goal might help me understand your dilemma.
Sometimes when you're knew to the language and know a few tools or tricks, you want to apply that knowledge and make it work for every problem. Back up a bit means slow down a little, explain what you're trying to do and see if you're on the right track before plowing ahead.Quote:

i think you and he share the same view and attitude over his own particular post toward me, which is quite odd but i won't care to ask for more.
look at this http://en.wikipedia.org/wiki/Operators_in_C_and_C%2B%2B
it talks about operators. it should help you.
Every1 here is to help you, dragon5
(char*) is language defined, such use to declaring object type is not allowed
Just trying to help. Your questions aren't exactly clear. Sometimes knowing more about what you're trying to do can help us get you a better answer.Quote:
