1、编写程序，实现WSAD”方向控制。功能描述：编写一个程序，当键盘输入为“WSAD”这四个按键中的其中一个（大小写皆可），输出相对应的方向。比如用户输入“W”，输出“左”。

2、编写程序，实现Hi‐Lo 猜猜游戏程序。实验描述：从1-1000 中随机选择一个数，反复让用户猜该数字是什么，直到用户猜对或用户退出为止。每猜一次告诉用户猜测的结果是对还是过大或是过小。使用一个标识值确定用户是否想退出。当用户猜对时报告其猜测的次数。每次游戏结束时询问用户是否想继续玩，直到用户选择结束。-1, the preparation procedures, WSAD " Direction Control Function Descr iption: Write a program that, when the keyboard input is" .
