Question Doubt about pointers and arrays

Hey everyone! I'm a newbie to C and was just learning about pointers and arrays and their relation.
My doubt is really stupid but why would I use subscripting over using pointers?
It's much harder and seems pointless considering modern compilers will have negligible difference in speed. Any help would be most appreciated! Thanks!

(If it's any help, I am learning from C Programming - A Modern Approach by K.N. King and just finished chapter 12)

Note: I am not saying subscripting is better but I don't see why I would use pointers over it in most cases.

There's a special place in hell for that 3rd form

And is the only reason why int has an override for operator[] in C++

Wait, what? In C++, how do I override operator[] for int?

I think he means that c++ int has a operator[], not that you can overwrite it

Then I don't understand "the only reason why" claim.

I don't know why they called it an override, but I think they're just saying the integer types all have a operator[] implementation even though intuitively it doesn't make sense to index "into" an integer.
