What are the side effects of pass-by-reference in programming?
Pass-by-reference allows a function to modify the original variable. This can lead to unintended side effects.
Can you give me an example of this?
Sure! If you pass an array to a function and modify it inside, the original array will also change.
How can I avoid these side effects?
You can use pass-by-value or create a copy of the variable before passing it to the function.
