Courses Plus Student 53,747 PointsPointers Part 2: Didn't we passed by address rather than reference by the end of the video?
During the Pointer Part Video of the 'Beyond the Basics' stage of the Objective C class, correct me if I'm wrong (it's been a while since I've done C instead of Objective-C), but isn't the function at the conclusion of the video more of an implementation of a function that demonstrates passing arguments by address its parameters?
We then deferenced the pointer to get to the value(s), correct?
Perhaps I was interpreting things wrongs but it seems by the end of the video the functions was referred to a function demonstrating a passing arguments by reference pattern, which I'm more familiar being a function that uses & for its parameters instead and changes automatically the same-named variable within the scope of the function. .

Treehouse Guest TeacherI think you are thinking of C++. In C, Pass-by-reference you pass the address of a variable (a pointer) and dereference that address within the function to read or write the actual variable.
