move constructor for pointer type?
c++, c++11
Solution
is a guaranteed to point to NULL ?
No, it will be unchanged. Initialisation of built-in types will never modify the initialiser. Only initialisation of a class type with a move constructor (or an evil non-constant copy constructor, such as `auto_ptr`) could modify it.
For example, if you used `std::unique_ptr` rather than dumb pointers, then `a` would be empty after the initialisation of `b`.
How about if `a` and `b` were ints?
Still no.
Problem
This is a simple question but I can't manage to find it on google: Is there a special move constructor for integral type(including pointers) For instance if I do: ``` int* a = new int(2); int* b = std::move(a); ``` Is it guaranteed to point to NULL? How about if a and b were `int`?
