Question

A ________ argument is passed to a parameter when the actual argument is left out of the function call.

A) false
B) true
C) null
D) default
E) None of these

Answer 1

The correct answer is 'D) default'. A default argument is used when an actual argument is not provided to a function call. This allows functions to be executed with fewer arguments than parameters specified.

Step-by-step explanation:

A default argument is passed to a parameter when the actual argument is left out of the function call. The correct answer to the question is 'D) default'. In computer programming, specifically when dealing with functions or methods, a default argument is a value that is automatically used if no argument value is provided during a function call. These default values are typically defined in the function signature. This feature allows functions to be called with fewer arguments than the number of parameters specified.
