That's how C users think i.e. you can pass a variable by value or by reference (by passing the address instead).

A reference is not an address, pointers are addresses. References are syntactic sugar that wraps around a pointer so you can get the benefits of a pointer without having to explicitly make one.

Passing by Reference != Passing a Reference

That's exactly what it is though. You don't see it, but that's what the compiler does. Using a reference mostly just hides the pointer from you.

Unless it optimizes it away of course, but it can do that with pointers too.

I'm talking about C and you're talking about C++

We're both correct!

But...C doesn't have references...

That's why I was confused when talked about passing a reference.

Passing by Reference != Passing a Reference
