Would the reward be for me or for my father when I give charity or donate from the money I receive from my father as an allowance while I am a student?

The money given by a father to his daughter becomes her property once she takes possession of it, and she may dispose of it as an owner disposes of her property, provided she is competent to donate. Therefore, the reward for charity from this money belongs to her. This does not preclude her father from also receiving a reward through another means, which is the reward for the money he gave her, because he helped her do good.
