Exercise 08-16:
Modify the alien game. Create a variable that represents the player’s life, starting with 100 points. The game ends when you find the alien or you run out of life (<=0). With each mistake, your life is decreased by a random value between 5 and 20 points, representing an attack by the alien. You can remove the part of the game’s code that limits the number of attempts and let only the player’s or alien’s life decide when the match ends. Show how much life the player has left before guessing the next tree number.
