using std::cin;
using std::endl;

class Configure

private:
 Configure() {} ; /////  原题掉了 {}  .......所以编译通不过!
public:
 static Configure* Instance();
public:
 int GetConfigureData() { return  data;}
 int SetConfigureData(int m_data) {  data = m_data; return  data; }

private:
 static Configure* _instance;

}

int main( )

   Configure* t = NULL;
   t = t->Instance();
   int d = t->GetConfigureData();
