scratch24点计算编程代码以下是一个用Scratch编写的24点计算程序的示例代码：当标志 flag 为2时重置所有变量和列表设置变量 round 为 1设置变量 score 为 0设置列表 cards 为 [1, 2, 3, 4]设置列表 operators 为 ["+", "-", "*", "/"]设置列表 expression 为空列表当标志 flag 为1时如果 round > 3，显示 "游戏结束！你的得分是 " + score，然后停止脚本否则，显示 "第 " + round + " 回合"随机选择一个数字n 从列表cards 中移除并添加到列表expression随机选择一个运算符 op 从列表 operators 中移除并添加到列表expression随机选择一个数字m 从列表cards 中移除并添加到列表expression显示列表 expression等待用户回答如果用户回答为 "24"，将 score 增加 10，并显示 "回答正确！你的得分是 " + score否则，显示 "回答错误！正确答案是 " + expression[0] + op + expression[1] + " = 24"将标志 flag 设置为2将 round 增加 1等待 2 秒重置列表 expression重置列表 cards 和 operators将 1、2、3、4 添加回列表 cards将 "+、-、*、/" 添加回列表 operators等待 2 秒将标志 flag 设置为1将标志 flag 设置为1。

24点游戏C语言代码及报告
24点游戏C语言代码及报告24点游戏一，问题分析二十四点游戏规则:给出4个数字，所给数字均为有理数，用加、减、乘、除(可加括号)把给出的数算成24(每个数必须用一次且只能用一次，先算出结果者获胜。
步骤:比如下面的例子:例:3、8、8、9，答案1:(9—8)×8×3答案2: 3×8 ?(9—8)答案3:(9—8?8)×3利用3×8,24、4×6,24求解我的主要想法是首先穷举的可行性问题。
我把表达式如下分成三类—— 1、无括号的简单表达式。
2、有一个括号的简单表达式。
3、有两个括号的较复4、杂表达式。
穷举的开始我对给出的四个数进行排列，其可能的种数为4*3*2*1=24。
我利用一个嵌套函数实现四个数的排列二，源程序及注释//首先穷举的可行性问题。

c语言小程序24点思路与代码
24点游戏使用说明书程序操作说明（1）在机器上装好TC2.0环境，读者在下载后直接解压到C盘即可。
（2）运行TC文件夹中的TC.exe文件，打开TC环境。
键盘上按下“F10”键，切换到菜单功能，使用方向键移动到File菜单，按向下方向键展开File菜单，按向下方向键，选择Load菜单项，按下回车键，输入文件所在路径及文件名称。
将源码导入到TC环境中。
（3）按键盘“F9”进行编译，然后按“Ctrl+F9”组合键运行程序。
24点游戏界面比较简单，没有复杂的操作。
读者掌握游戏规则后。
运行程序后进入到24点游戏的功能菜单界面。
在此界面可以选择开始游戏，查看游戏规则或者退出游戏3个选项，其效果如下图所示。
24点游戏功能菜单界面在功能菜单界面输入数字2可以查看游戏规则。
游戏规则界面如下图所示。
戏规则界面在功能菜单界面输入数字1便进入游戏界面，即可按照要求进行游戏，游戏界面如下图所示。
