A Pointer contains an address that points to data.
A string is any finite sequence of characters (i.e., letters, numerals, symbols and punctuation marks).

There are two types of strings -- C and C++.
A c-style string is a null-terminated sequence of characters -- certainly considerably less than infinite! That means that the string ends with the first byte that contains 0.
The C++ string is a class in std library. There are other c++ string classes too, but the standard one is in std namespace.

no its not -- it is still just a pointer, it just contains the address of a c++ class.

string ponter = new string;
Shouldn't that be
string* ponter = new string;:?:

I think it was meant to be a joke :rolleyes:
BTW jwenting is more of a java person, so perhaps that's where the confusion came from.

In the interest of not confusing the other poster, I'd like to point out that A.D. means 'address of an object [of type string]'.
