C++11: Using a List Initializer with a Dynamically Allocated Built-In Array

Prior to C++11, when allocating a built-in array of objects dynamically, you could not pass arguments to each object’s constructor—each object was initialized by its default constructor. In C++11, you can use a list initializer to initialize the elements of a dynamically allocated built-in array, as in

The empty set of braces as shown here indicates that default initialization should be used for each element—for fundamental types each element is set to 0. The braces may also contain a comma-separated list of initializers for the array’s elements.
