Harry Potter Readers? Please read this!?

Okay, so a guy that I know who read all the Harry Potter books said that Voldemort kills Harry. Is that true? If so can you tell me how? And if not, tell me how Harry kills Voldemort? Thanks. Any other details that might be good for me to know would bve nice. I'm okay with spoilers. He already spoiled it for me! =) No mean comments please.
