If a class does not have a default constructor, the new initializer must be provided when any object of that class is allocated. The arguments of the new initializer must match the arguments of a constructor.
You cannot specify an initializer for arrays. You can initialize an array of class objects only if the class has a default constructor. The constructor is called to initialize each array element (class object).
Initialization using the new initializer is performed only if new successfully allocates storage.
