/*
Playing a console-based game
To solve the problem, your program must be able to:
Choose a random word to use as the secret word. That word is chosen from a word list, as described in the following paragraph. Keep track of the user’s partially guessed word, which begins as a series of dashes and then updated as correct letters are guessed. Implement the basic control structure and manage the details (ask the user to guess a letter, keep track of the number of guesses remaining, print out the various messages, detect the end of the game, and so forth) */
简单说需求就是从一个单词集合中随机选取一个单词， 假设猜想单词school， 就在控制台上输出 _ _ _ _ _ _，根据英语普遍规律，绝大部分的单词都有元音字母，所以从元音字母开始猜比较容易。假设用户猜字母O，单词school中出现了，就在单词上预留的位置中填写此字母，_ _ _ o o _ 当用户们猜测的单词为school中并未出现的字母，则将在控制台中输出最近一次单词的状态。若给定猜测次数内，单词仍未猜出，则系统获胜，若猜出此单词，则为用户获胜。
以下给出代码实现：
