Short answer

Question: When an argument is passed to a function, and only a copy of the argument is used, it is said to be passed by ______. Answer: value

Step-by-step solution

Understanding Argument Passing

When an argument is passed to a function, there are two main ways it can be transferred: pass-by-value or pass-by-reference. In pass-by-value, a copy of the argument is made, and the function works with that copy, which means any changes made to the argument within the function do not affect the original value. On the other hand, in pass-by-reference, a reference (address) to the original argument is passed, and any changes made to the argument within the function affect the original value.

Fill in the Blank

Based on the understanding of argument passing, we can now fill in the blank of the exercise. When only a copy of an argument is passed to a function, it is said to be passed by "value". So the missing term is "value".
