-When a `class` or `struct` has no constructor, you provide the list elements in the order that the members are declared in the `class`. If the `class` has a constructor, provide the elements in the order of the parameters. If a type has a default constructor, either implicitly or explicitly declared, you can use default brace initialization (with empty braces). For example, the following `class` may be initialized by using both default and non-default brace initialization:
