运行界面截图看看
42行错误，将所有[20]这样的中括号带数字的都删掉。只需要变量名，不要带数组大小，带了就是数组的第20个元素的意思啦。
后面的printf语句也都是这样的错误
但57行又是写对了，参考一下吧。得统一啊
printf语句的num是对的，后面都错了
结构体的使用不太熟悉哦，里面错误比较多，给你修改了代码，自己参考，如果有问题私聊。

Q：请问，我写的子程序在黑窗口中无法成功运行，每次输入完命令后窗口会立即关闭，不知道是什么原因，希望能得到帮助，谢谢。
A：这个问题可能是由于程序执行结束后窗口自动关闭导致的。你可以在程序的末尾添加代码来让程序暂停，以便你有时间查看程序执行的输出。你可以试试用以下这段代码：
// 在代码的末尾添加以下一行，以等待用户输入，防止程序结束后黑窗口自动关闭。
system("pause");
此外，如果你使用的是 Visual Studio，你也可以添加以下一行：
system("pause > null");
该语句可以将暂停输出到 null 空设备上，避免弹出 CMD 窗口。如果你在其他 IDE 或者命令行上运行程序，你可以在命令行上执行 exe 文件，并手动输入 pause 命令来达到同样的目的。
