persist

A function __________ eliminates the need to place a function definition before all calls to the function.

prototype

Default arguments are normally specified in the function

prototype

When used as parameters, _________ variables allow a function to access and modify the parameter's original argument.

reference

A void function is one that

returns no value

stub

In a function header line, you are required to furnish

A static local variable is one

whose value is retained between function calls

Overloaded functions are functions.
