24点游戏是经典的纸牌益智游戏。从扑克中每次取出4张牌。使用加减乘除，第一个能得出24者为赢。（其中，J代表11，Q代表12，K代表13，A代表1）随机生成4个代表扑克牌牌面的数字字母，程序自动列出所有可能算出24的表达式，用户初始生命值为一给定值（比如3），初始分数为0。随机生成4个代表扑克牌牌面的数字或字母，由用户输入包含这4个数字或字母的运算表达式（可包含括号），如果表达式计算结果为24则代表用户赢了此局。使用计时器要求用户在规定时间内输入表达式，如果规定时间内运算正确则加分，超时或运算错误则进入下一题并减少生命值（不扣分）。所有成绩均可记录在TopList.txt文件中。(24 point game is the classic card puzzle game.Take 4 cards at a time from poker. Use the first 24 can be reached add, subtract, multiply and divide, to win.
