问题出在函数loginScreen（）中，函数getDetails（）得到运行，但是一旦完成3221225477，有人可以指出我为什么会这样吗？看来我正在正确分配内存和所有内容。我试图找出为什么会这样，但是我什么也找不到。

我对编码很陌生，所以请对我轻松一点这是我的代码/ *打开文件* / FILE * openFile（char filename []，char filetype []）; / *读取护士人数* / int readNurses（void）; / *标题* /无效...

3221225477是十六进制的0xC0000005，它是NTSTATUS代码STATUS_ACCESS_VIOLATION。您的程序以某种方式破坏了其工作内存。而是在Linux上编译程序；然后您可以在valgrind下运行它，并确切告知问题出在哪里。
