Question

17) Which data structure does not support indexing?
​

Answer 1

The structure must holds fixed size std::strings so that the number of its elements is finite (100 - 10000000).

Answer 2

Set data structure does not support indexing.

Indexing

It refers to the process of gathering information about the data for making the searchimg process quicker and easier.

Data structure

It is a storage where computer stores and organise or arranges data as it can be updated or accessed for later purposes.

Set data structure

It is a type data structure that allows unique elements of the same type to store in a sorted order.

As the set data structure does not bother about the position of the elements ,

Hence it does not support indexing.
