cin.get() in string class or overloading

I have a string class at the below:

class Mystring
{
        private:
            char *letter;

        public:

            friend ostream & operator <<(ostream  &out, const Mystring& s);
            friend istream & operator >>(istream &in,Mystring& s);
};

this is in the main function:

int main()
{
    Mystring s[10];

    cin.get(s,10);
    cout << s;

    _getch();
    return 0;
} 

when i use cin.get i get error like this

Error 1 error C2664: 'std::basic_istream> &std::basic_istream>::get(std::basic_streambuf> &,_Elem)' : cannot convert argument 1 from 'Mystring' to 'char *' c:\users\thai\documents\visual studio 2013\projects\overloading\overloading\main.cpp 11 1 Overloading

i think i should create an overloading for cin.get() , but how ??
