Iterators Example

#1

Why only start cant be used to use iterators?

#2

Hi @Arnabiswas, can u pls elaborate what do u mean by only start

#3

I want to know why *start is use as iterator?Can I used without ’ * '?

#4

No, u cannot use start without ‘*’ (to compare with key). As, u would have seen, start=list.begin() and hence is storing the address of the beginning of list. So, in order to get the value present at the beginning of list, we will have to use *start (using * we try to access the value present at start address here).

Moreover, We are using start as iterator since it is storing the address of beginning of the list through which we wish to iterate.
Hope this resolves ur doubt.
