A pointer to the list would allow you to modify whatever’s at that pointer’s address though. If you want to look at the list and not edit it you pass by const reference 99% of the time (or you pass a copy) and if your language doesn’t have that I don’t like it.








I’m not even a C++ wizard or anything (though it’s my most advanced language) so I’m not gonna argue that is good or bad, that sounds fine to me for a wide range of applications already.
But the way is see it, pointers kinda allow you to use “raw memory” which is an actual thing that’s gonna be handled by the program one way or another, and it’s a way to relatively refer to memory for example. As some guy on stackoverflow put it “That guy at the end for the bar” vs “Bob” can be very useful. Especially when using data structures you don’t know the size of at compile time.
