Not tested, but I think it should work...

Sorry,

Just copied and pasted...

It its not running...

You could always try writing it yourself.

Just a thought.

(I suggest not to show it your teach since he might not believe it is yours;)

Good thought. Been trying to crack all day....

@coder777

Ha ha. Incidentally am not doing for the teacher... I am doing it for myself... Besides I do not fear saying what I don't know.

OK looks good but honestly a good counter will change from one number to another without forming an array. Like continuously count from 1 to 100... Just display one number at a time. That way I will know I am in number one number 10 or whichever number... Just like what a digital stop watch will do... well sort of...

That is my biggest challenge.... especially the bit of counting / dispalying 1 to 100 numbers one number at a time!!!

Try this, does it do what you need? I sort of brute-forced it

            checkTime -= (double)(CLOCKS_PER_SEC);
        }
    }
    return 0;
}


This one works just like a real timer in base 3.

Output (Set to 3 so it is not to long):
0 : 0 : 1
0 : 0 : 2
0 : 1 : 0
0 : 1 : 1
0 : 1 : 2
0 : 2 : 0
0 : 2 : 1
0 : 2 : 2
1 : 0 : 0
1 : 0 : 1
1 : 0 : 2
1 : 1 : 0
1 : 1 : 1
1 : 1 : 2
1 : 2 : 0
1 : 2 : 1
1 : 2 : 2
2 : 0 : 0
2 : 0 : 1
2 : 0 : 2
2 : 1 : 0
2 : 1 : 1
2 : 1 : 2
2 : 2 : 0
2 : 2 : 1
2 : 2 : 2
0 : 0 : 0
0 : 0 : 1
0 : 0 : 2
0 : 1 : 0

I have really no idea what you're talking about. good counter? forming an array?

If you want another output (like that from Smac89):
1
2
3
4
5
6
7
8
9
 
  void Out()
  {
    if(m_Next)
    {
      m_Next->Out();
      std::cout << " : ";
    }
    std::cout << m_Value;
  }


if you understand the solution from Smac89 better just use that
