Random number class HELP

[alex067]

There's an error in the program where when you ask for the min value and max value of the array you wish to see, the output is just a complete mess.

[long double main]

The problem is that the list in main is not the same list in createList (doing list = new int[size]; in createList only changes the list in that function, not the one in main).

So change your createList function to this:
void createList(int*& list, int &size);
