实战项目——QuickHit

任务描述

1.根据输入速率和正确率将玩家分为不同级别
2.级别越高，一次显示的字符数越多，玩家正确输入一次的得分也越高
3.规定时间内完成规定次数的输入，正确率达到规定要求，则升级
玩家最高级别为6级、初始级别一律为1级
4.用户错误输入一次，游戏结束

分析

1.玩家类:级别、当前级别时间、姓名、得分，玩游戏()
2.级别:字符数、得分、次数、规定时间、级别号
3.6个级别的常量:
4.游戏类:玩家，生成字符()、玩游戏()

流程控制:
欢迎
循环（根据当前级别的显示次数)
如果循环正常走完，升级
级别编号、时间初始化为当前时间，已用时间初始化为0
输入错误，退出
超时，退出
