What are the different ways to pass parameters in C++?

In C++, parameters can be passed by value, by reference, or by pointer. Each method has its own use cases.

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

Sure! Passing by value creates a copy of the variable, while passing by reference allows the function to modify the original variable.

When should I use passing by reference instead of passing by value?

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

Are there any downsides to passing by reference?

Yes, passing by reference can lead to unintended side effects if the original variable is modified, so it should be used carefully.
