What are parameters in C++?

What are parameters in C++?

Parameters in C++ are variables that are passed to functions to allow them to receive input values.

Can you explain the difference between pass by value and pass by reference?

Sure! Pass by value means a copy of the variable is passed, while pass by reference passes the actual variable, allowing modifications.

When should I use pass by reference?

Use pass by reference when you want to modify the original variable or when passing large objects to avoid copying overhead.

Are there any drawbacks to using pass by reference?

Yes, it can lead to unintended side effects if the original variable is modified unexpectedly.
