In English one can place a question tag after statement by adding an interrogative phrase. This usually requires the interlocutor so affirm/confirm or reject the statement.
Statement: You have not eaten, have you?
Response: Yes I have. or No I haven't.
Statement: You will go to there, won't you?
Response: Yes I will. or No, I won't.
Does such a thing as question tags exist in French? If so, how are they formed? If not, how does one request an affirmative or negative answer to a statement?
