Real quick question about operator overloading

Hi guys,

I am writing a program where I need to overload the + and - operators to add or subtract data in a linked list and put this data into a new linked list.

Some of the code has been provided and one of the things that gets passed to the add or subtract functions is called *this. Is *this what is on the left hand side or what does *this represent?

Thanks guys.

passing *this in a function passes a reference or copy of the object whose method is currently being executed into the function being called.
