hello @officialharshit1996
in the above code , we are just overloading [] operator

#3

tell me , how it is working like we are returning int but return type is int&, how given statement is workingv[2]=2

#4

i.e when we are doing v[2]=6 then refrence of 3rd element of vector is returned and 6 is assigned to it as value.

we are returrning the reference (int&) because because we want to make changes in original array only
