Hello, Don!
I think, that a good books for c and c++ beginners are books of Herbert
Shildt. For example, c++ complete reference. That was my choice when i
studied c and c++.
What about your code? It seems like everything okay, except one moment. I
think, that you forgot to allocate your ponters min and max:
double *min = new double
double *max = new double
Best regards, Vladimir.
