Показать описание
Default arguments is a value provided in a function declaration that is automatically assigned by the compiler if the caller of the function doesn’t provide a value for the argument that originally includes a default value.

Allows a function to be called without providing one or more trailing arguments.

(The trailing arguments in the argument list of an operation may be optional. If these trailing arguments are missing in a call of an operation the default argument values given in the specification are used.)

Default arguments start from the right most side,(order is right to left) otherwise the compiler may throw an error. You can’t make a default argument in between various arguments.
