Obtains an allocator to be used on a copy-construction of a container that uses alloc.
In the non-specialized definition of allocator_traits, this member function returns alloc.select_on_container_copy_construction() if such an expression is well formed. Otherwise, it returns alloc. A specialization for a specific allocator type may provide a different definition.
allocator_type is an alias of allocator_traits's template parameter.

Select on container copy construction
In the non-specialized definition of allocator_traits, this member function returns alloc.select_on_container_copy_construction() if such an expression is well formed. Otherwise, it returns alloc. A specialization for a specific allocator type may provide a different definition.
Parameters
- alloc
- Allocator object
allocator_type is an alias of allocator_traits's template parameter.
Return value
The allocator object to be used in the copy-constructed container object.allocator_type is an alias of allocator_traits's template parameter.
