my required output of "hi" is one. Pls tell me

Answer 1

What you do is clear the string that is returned from the string, not the string inside . You really need to doss.str("")

See here: How to clear a stringstream variable?

Answer 2

The "clear ()" function is inherited from ios and is used to clear the stream error state.

, :

stringstreamObject.str("");

Answer 3

:

ss.str("");
