嗨，我在运行程序时遇到一个 C 语言问题消息“x.exe 已停止工作”。例如 x 是文件的名称。我该如何修复它？

您需要花时间学习如何使用 IDE 的调试器以及如何检查代码和收到的任何编译器警告。你的问题出在 main() 中:

在这里，您创建了一堆提交结构实例:

submission sub1,sub2,sub3,sub4,sub5,sub6;

然后，你尝试做这个作业:

sub1.stud1[0].id= 23423446;

如果您查看提交声明:

struct submission
{
student *stud1;
student *stud2;
datetime *dt;
};

您将看到 Stud1 是指向学生的指针，而不是学生。所以没有为该结构分配内存。指针指向垃圾。然后，您尝试取消对指针的引用，并发生错误、段错误。您需要将其初始化为学生类型的有效内存块。这留给你作为学习练习。
