Question: What is the default Function arguments?

Answer: Default function argument is a function argument with a default value. Callers of this function have a choice whether to pass a value for default argument or not. If a function call passes a value for default argument it is used as its value. If a function call does not pass a value the default value specified in the function definition is used.

A function may have any number of default arguments. However all these arguments must follow all mandatory arguments. That is first you have to specify all non-default or mandatory parameters and then all default parameters.
