How to call object T from constructor copy T(const T&)?

Question

I have a copy constructor T::T(const T&). The object has two properties, let's say color and height. This means I need to assign the color and the height from the object in argument to my object. Problem is I don't know how to call the argument because it is not named.

If the argument is named, let's say t, code looks like this:

T::T(const T& t) {
    color = t.color
    height = t.height
}

But in my case there's no t argument. What should I replace the question mark ? with in the following code:

T::T(const T&) {
    color = ?.color
    height = ?.height
}

Thanks for help!

Answer 1

As @some-programmer-dude mentioned, I was confused about the difference between function declarations and definitions.

My declaration was T::T(const T&) but that didn't stop me from defining an argument t in my definition T::T(const T& t).

Thanks!
