That question is language-agnostic, this one is specific to C++.Barmar– Barmar2013-03-02 07:24:22 +00:00Commented Mar 2, 2013 at 7:24

string is a class/object, with methods and encapsulated data.
A char array is simply a contiguous block of memory meant to hold chars.

when i search while asking question i didnt find duplicate one.. so i came to ask new .. i will mind this.. thank you
(1) char array is just a block of char type data:
e.g. char c[100]; // 100 continuous bytes are allotted to c
(2a) By string, if you mean char string then, it's little similar to array but it's allocated in the readonly segment of the memory and should be assigned to a const char*:
e.g. const char *p = "hello"; // "hello" resides in continuous character buffer
[note: char c[] = "hello"; belongs to category (1) and not to (2a)]
(2b) By string if yo umean std::string then, it's a standard library class from header and you may want to refer its documentation or search on web
