operator_surrogate_func:未找到匹配的重载和其他2个错误

我写了一段代码，创建了一个可以修改和管理的总线列表。整个管理过程是通过在控制台中写入字符串来进行的。在运行代码后，我收到了3个错误，因此我所理解的没有一个可以修复。代码是这样计划的：

NEW_BUS-通过获取新巴士的编号、停靠站数量和停靠站列表，将其添加到列表中。ALL_BUSES-按字典顺序显示所有总线(按名称(STOPS_FOR_BUS-显示所有站点特定的总线跟随。BUSES_FOR_STOP-Diploy所有经过特定站点的公交车。

以下是错误列表：1.operator_surrogate_func：未找到匹配的重载2.无法专门化函数模板的未知类型std:：less：：运算符(((_Ty 1&，_Ty2&&amp；(3.非法表达

所有错误都来自xutility文件的617行。
