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.

Default Function arguments::

For eg: Suppose Function funcDefaultArg with two patameters of type int.

When declared like this :

int funcDefaultArg(int x=10,int y=27)

is said to be as default function arguments.

FYI

In C# Passing Default values for the parameters is not allowed.

C# does not support optional arguments.

you can use function overloading to achieve the same.
