Allocates and constructs an object of type T passing args to its constructor, and returns an object of type shared_ptr<T> that owns and stores a pointer to it (with a use count of 1).
This function uses ::new to allocate storage for the object. A similar function, allocate_shared, accepts an allocator as argument and uses it to allocate the storage.

Make shared_ptr
This function uses ::new to allocate storage for the object. A similar function, allocate_shared, accepts an allocator as argument and uses it to allocate the storage.
Parameters
- args
- List of elements passed to T's constructor.
Args is a list of zero or more types.
Return Value
A shared_ptr object that owns and stores a pointer to a newly allocated object of type T.Example

Output:
*foo: 10 *bar: 20 *baz: 30 40 |
