c语言lnk1120 c - 致命错误LNK1120：C中1个未解决的外部问题 - 堆栈内存溢出

通常，当我收到此错误时，创建一个新项目并复制并粘贴该代码修复，但现在没有。

这是输出：

1>------ Build started: Project: myList, Configuration: Debug Win32 ------

1> List.cpp

1>List.obj : error LNK: unresolved external symbol "void __cdecl printStd(struct Student >*)" (?printStd@@YAXPAUStudent@@@Z) referenced in function _main

由于这是一个很长的代码，您实际上不需要检查它，所以没有错误..即使控制台也这么说：D

那么这个错误是什么意思？为什么我得到它？我该如何解决？ 它导致我找到一个甚至不存在的exe。

谢谢
