What are the different parameter types in C++?

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

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

Sure! Passing by value means a copy of the variable is made, while passing by reference means the original variable is accessed directly.

When should I use pointers instead of references?

Use pointers when you need to manage dynamic memory or when you need to represent 'no value' with a null pointer.

Are there any performance implications between these methods?

Yes, passing by reference can be more efficient for large objects since it avoids copying, while passing by value can be simpler for small data types.
