Parameter of sort function

#1

In the video, it said that it takes start and end as of the array as a parameter, but then we used a and a + n. But a is the array,. So I didn’t get why we used a and a+n.

#2

Yeah we have to give the start and end as parameter but I think you interpreted this wrong.

have you ever sorted a vector?
we sort it like this:

vector<int> v={1,4,6,3,2,9,7}
sort(v.begin(),v.end());

Now,
what we do here, we give pointers (as v.begin() and v.end() are pointers) to this sort function which will tell me about its starting and ending.
I haven’t gave its index. So therefore we give a (which is pointing to the start of the array) and a+n ( which is pointing at the end).

I think I cleared your doubt. If it is not cleared yet, you can reopen this again.
