Redefinition error

[karatekid]

I am getting an error and I don't know how to fix it.
Statistics.cpp:106:1: error: redefinition of ‘Statistics::Statistics(int*, int)’

Well, it means what it says - you are defining Statistics::Statistics(int*, int) twice - once in the class declaration, and once in your .cpp - remove the definition from the header and you're good.

I did remove the definition from header and I get a different error.
Statistics.cpp:106:1: error: prototype for ‘Statistics::Statistics()’ does not match any in class ‘Statistics’
Mode.h:41:30: error: candidates are: Statistics::Statistics(const Statistics&)
Mode.h:48:5: error: Statistics::Statistics(int*, int)

No, you didn't remove the definition in the header file. It's still there.

class Statistics:public Mode {
protected:
    double sum;//Stores the sum of the array
    double average;//Stores the average of the sum of array
    int middle;//Store number of the array
    float median;
public:
    Statistics(int *a, int c): Mode(a, c)
    {
        sum=0;
        average=0;
        middle=0;
        median=0;

And do you actually read these error messages? It says that this:
Statistics::Statistics()

doesn't correspond to any method you declared in your class declaration.
