If we can iterate over the string using simple loop. Then why we need iterators? Is there any benefit of using iterators?
Because in both cases we are using one loop.
What is the need of iterators?
hello Mohit,
a) performance wise i think there is not much difference
b)Using iterators makes the for-loop slightly simpler, you can avoid typo-type mistakes by using the wrong index or wrong symbol
c) The main advantage of using iterators is generality. That is, you can write only one function and use it for different containers:
