When do we use an indexer?

Answer 1

Indexers have a variety of uses in (natural) language processing, etc, that's my limited understanding of the matter... Read on...

Answer 2

indexer we use it when we need to get something that is in an array or in a list. don't be frustrated by the term "indexer" it only mean that you tell the compiler to get this ( indexer ) from the list or array or a group of types. indexer is every type you use. for example from the array you want to get the fifth one so you say array[4] the number 4 is the indexer of type int.
