24点游戏

Think:

部分 卡牌 会出错， 近期会进行改正修改。

C语言实现纸牌计算24点小游戏

　利用系统时间设定随机种子生成4个随机数，并对4个数字之间的运算次序以及运算符号进行枚举，从而计算判断是否能得出24，以达到程序目的。程序主要功能已完成，目前还有部分细节未处理，待完成ing…对于代码中的错误，恳请批评指正。

游戏描述：

　　A-10：分别代表数字 1-10。

　　J,Q,K：均代表数字1。

　　考虑到部分地方的规则,J,Q,K 也可以当成10 ，或者直接代表本身所代表的数字，即11、12、13来运算。

　　使用加减乘除，能得出24者为赢，存在无解情况。

　　游戏开始得分为1000分,每一秒钟减少1分,当答对一次时,分数增加100分。（暂未实现）
