Isn't this one of those implementation defined constants?

So no, it is not.

The range is 2^32-1.

Fearum, you have been here long enough to know not to block or lock questions.   You may be right, but that is up to the User to decide, if he/she  uses you comment as an answer, then good for you.

I must reject the proposed answer and return it to the active question listin.

Thanks,

yes.

To find out programmatically you can use:

#include <limits>
main
{
cout << "limit of unisgned int" << std::numeric_limits<unsigned int>::max();
};
