5.ios functions are member functions while manipulators are non-member functions.

Answer 2

Answer:

Difference between IOS member functions and Manipulators.

Explanation:

IOS Functions - ios is the name of a class that implements many features of the input/output system. It returns value. User cannot create it's own ios functions. They are single and impossible to combine. It needs <iostream>.

Manipulators - They are those functions that are designed to work with the inserter i.e. <<  and extractor i.e. >>  operators in association with one of the input/output stream objects. They do not return value and user can define it's own manipulators. They are non-member functions. They can be applied in chain. We need to include <iostream> to use manipulators without arguments where as include <iomanip> to use manipulators with arguments.
