What's the signed-ness of 5?
Positive. A positive number can be assigned to an 'int' if there is no
size
issue.
It can also be an unsigned.
What's the problem that I'm obviously missing?
When you index a pointer, is the index signed or unsigned?
An index can be either. What's the problem here?
auto x = p1 - p2;
What's the type of x?
ptrdiff_t, signed counterpart of size_t
