  • BIt creates a constructor named "new" with parameters _x and _y, and initializes variables x and y with the provided values.
  • CIt defines a default constructor that initializes variables x and y to the values of _x and _y.
  • DIt declares a class with default values of 10 for variables x and y, which can be accessed using the "new" method.
