Help w/ c++ assignment...

[GaganW18]

Hi all.. I have recently started a c++ class and I need some of your help with...

Ive understood all thats required but below is the basic header file for which I will have to create an implementation.

I have a stattest.cpp, .h file, & statexam.cpp and am currently working on all the functions. I will post any questions I may have. In the meantime, if you can leave me with any 'tips' to help me make sure I am on the right path will be fine.

>>I am not asking for a full code for my program, just some helpful tips!

Below is the given .h file :

#ifndef STATS_H     
#define STATS_H
#include <iostream>

namespace stat
{
    class statistician
    {
    public:
        // CONSTRUCTOR
        statistician( );
        // MODIFICATION MEMBER FUNCTIONS
        void next(double r);
        void reset( );
        // CONSTANT MEMBER FUNCTIONS
        int length( ) const;
        double sum( ) const;
        double mean( ) const;
        double minimum( ) const;
        double maximum( ) const;
        // FRIEND FUNCTIONS
        friend statistician operator +
            (const statistician& s1, const statistician& s2);
        friend statistician operator *
            (double scale, const statistician& s);
    private:
        int count;       
        double total;    
        double tiniest;  
        double largest;  
    };

    // NON-MEMBER functions 
    bool operator ==(const statistician& s1, const statistician& s2);
}

#endif

Edit: I am currently working on the program and as soon as I have worked out different functions, I will post any questions I may have.

Thanks!
