What are some real-world examples of pass-by-value and pass-by-reference?

Can you explain the difference between pass-by-value and pass-by-reference with real-world examples?

Sure! Pass-by-value means that a copy of the variable is passed to functions, while pass-by-reference means a reference to the original variable is passed.

Can you give me a real-world example of pass-by-value?

Absolutely! Think of pass-by-value like sending a photocopy of a document. If you make changes to the photocopy, the original document remains unchanged.

And what about pass-by-reference?

Pass-by-reference is like giving someone the original document itself. If they make changes, the original document is altered.

Are there programming languages that use one method over the other?

Yes, for example, Java uses pass-by-value for primitive types and pass-by-reference for objects, while Python uses a model that can be seen as pass-by-object-reference.
