Hello kerem59,

If http://www.cplusplus.com/forum/beginner/274858/ did not answer your question I am not sure what you are looking for except it is the function(s) you hae not written yet.

In the "create_data" function line 33 should come after line 41 to work properly.

After that I will have to find what I worked on earlier to see what I did.

Guess this means that you have your answer?

That was fun to work on.
