#include
#include
using namespace std;
templateclass Data{
    string header;
    T data;
public:
    Data(string h, T d){header = h, data = d;}
    void WriteData()
    {
        cout<    }
};
int main(int argc, _TCHAR* argv[])
{
    Data idata("Roll", 100);
    Datasdata("Name","Jakir");
    idata.WriteData();
    sdata.WriteData();
    return 0;
}
