    用戶登陸管理系統：
        1. 註冊新用戶
            username
            password
            gender
            email
            age

        2. 用戶登陸
            username
            password
        3. 註銷用戶
            username
            password
        4. 顯示用戶信息
        5. 退出系統




	1. 用戶名和密碼分別保存在列表中;
	2. 用戶登錄時，判斷該用戶是否註冊;
	2. 用戶登錄時，爲防止黑客暴力破解, 僅有三次機會;
	3. 如果登錄成功，顯示登錄成功(exit(), break).
