  • You didn't set `cx`, which the slow `loop` instruction uses implicitly. If `cx=0` at the start of your program, your loop will run 65536 iterations. – Peter Cordes May 05 '18 at 18:02
  • Your `jne` is a no-op because it either branches to the next instruction or falls through to the next instruction; you probably want to fix that too. – Joe White May 05 '18 at 18:03
  • Peter cordes please guide me where i need to put cx = 0. How to fix please give me an example i am new to assembly. – Mishal Rehaj May 05 '18 at 19:58
