Generally when we use the auto datatype?

hello @udatta
…

auto is not datatype . it is keyword that automatically detects datype of data.
whenever u dont want to explicilty mention the datatype .
u can use auto keyword.

most of the times we use in loops, in for each loop and for iterators becuase their datatype are generally long so instead of explicitly mentioning the type we use auto.
