Tnx Ulrich for you reply but now I have another problem, my Visual Studio.Net compiler says there is an error at "while (cin >>s)" line and it said that "error C2679: binary '>>' : no operator found which takes a right-hand operand of type 'std::string' (or there is no acceptable conversion)" what should I do now????

You should make sure you are including the correct header files. As Jochen indicated, you should have:

#include <string>
#include <iostream>
using namespace std;

If you were using

#include <iostream.h>

you need to get yourself a new book on C++.
