题目要求错题本管理程序：利用链表实现错题本管理程序。其中错题信息包括题目、错误信息、答案分析、心得体会、错题来源、错题原因、难易程度、题目类型、知识点等多项信息。具体实现的管理功能如下：1 输入并显示错题的信息；2 可实现错题信息的添加；3 查询至少提供按知识点和题目类型两种方式；4 修改提供查询后进行修改；5 删除依据指定的信息知识点和题目类型查找后删除错题；6文件的导入和导出从文件中读取若干条

#include #include using namespace std;

// 定义错题信息结构体 struct WrongQuestion { string question; string errorInfo; string answerAnalysis; string learningExperience; string source; string reason; string difficulty; string type; string knowledgePoint; WrongQuestion* next; };

// 全局变量：头指针和尾指针 WrongQuestion* head = nullptr; WrongQuestion* tail = nullptr;

// 函数声明 void addWrongQuestion(); void displayWrongQuestion(); void queryWrongQuestion(); void modifyWrongQuestion(); void deleteWrongQuestion(); void importFromFile(); void exportToFile();
