no matching function for call to ‘Mode::Mode()’

[karatekid]

I am getting an error when I try to run my mode median mean program. What is causing this error.

Mode.h:41:29: error: no matching function for call to ‘Mode::Mode()’
Mode.h:19:5: note: candidates are: Mode::Mode(int*, int)
Mode.h:10:12: note: Mode::Mode(const Mode&)

The Rule of Three strikes again! You tried creating a "Mode" object without arguments without defining what to do in your code.

class Mode {
protected:
    int *b;//Sorted Array
    int bSize;//Size of Sorted Array;
    int max_Freq;//Frequency of the mode set,
    int num_Modes;//Number of Modes, size of Mode Array
    int *m;//Mode Array
    int *mark_Sort(int *,int);//Utility function for the class
public:
    Mode(int *pList, int nCount) // understand this is legal, this is the default constructor
    {
          // init things here but don't run anything.
    };
//    Mode(int *,int); // this is not.
    ~Mode(){//Constructor inputing the initial
        delete []b;
        delete []m;
    }

};
class Statistics:public Mode{ //This the line of error
