学生成绩管理系统

用单链表数据结构完成c++的学生成绩管理系统，此系统的具体功能如下：

本人小萌新一个，遇到BUG是正常现象。并且类与对象写的不太理想。@-@

写了一个Database存放所有数据，但这肯定浪费资源，你们看着改改吧。

class DataBase { public: virtual void run();//多态 void setID(int ID); void setName(string Name); void setSex(string Sex); void setChinese(double Chinese); void setMath(double Math); void setEnglish(double English); void setAverage(double Average); void setSum(double Sum); void setNews(string news); void setSolute(string solute); void setAccount(string A); void setPassword(string P); void setWordprotect(string W); void setNext(DataBase* next); int& getID(); string& getName(); string& getSex(); double& getChinese(); double& getMath(); double& getEnglish(); double& getAverage(); double& getSum(); string& getNews(); string& getSolute(); string& getAccount(); string& getPassword(); string& getWordprotect(); DataBase* getNext(); private: int ID = 0; //学号 string Name = ""; //姓名 string Sex = ""; //性别 double Chinese = 0; //语文 double Math = 0; //数学 double English = 0; //英语 double Average = 0; //平均分 double Sum = 0; //总分 string News = ""; //信息反馈 string Solute = ""; //解决方案 string account = ""; //账号 string password = ""; //密码 string wordprotect = "";//密保 DataBase* next = nullptr;//指针域 };

登录系统功能。

动画效果进入主界面，可选择教师端或学生端。

void menu() { cout << "\t\t*********************************************" << endl; cout << "\t\t*****\t\t 1.教师端\t\t*****" << endl; cout << "\t\t*****\t\t 2.学生端\t\t*****" << endl; cout << "\t\t*****\t\t 0.退出 \t\t*****" << endl; cout << "\t\t*********************************************" << endl; } void Homepage() { WelcomeScreen(); while (1) { system("cls"); menu(); cout << "\t\t选择："; DataBase* F = NULL;//多态进入不同界面操作         //这里也可以传对象实现多态 string acc; cin >> acc; if (acc == "1") { F = new Teacher(); F->run();//老师界面 } else if (acc == "2") { F = new Student(); F->run();//学生界面 } else if (acc == "0") { F = new DataBase(); F->run();//退出 break; } else { continue; } } } int main() { Homepage(); return 0; }

教师端：可以登录账号、注册账号、注销账号、找回注销的账号、修改密码以及退出。

学生端：可以登录账号、注册账号、注销账号、修改密码以及退出。与教师端大同小异。

教师端功能

#pragma once #include"DataBase.h" class Teacher : public DataBase { private: //学生不可继承的功能 bool Turnitin(int ID);//查重 void CreateDataBase(); //添加学生 void Sort(); //按成绩排序 void M1odify(); //修改学生信息 void Delete(); //删除学生信息 public: Teacher();// head节点 ~Teacher(); virtual void run(); void login(); //账号登录 void regist(); //账号注册 void logout(); //账号注销 void find(); //账号找回 void modify(); //修改密码 void read(const char* file, DataBase* head); void write(const char* file, DataBase* head); void operat(); //运转器 void Search(); //查找学生信息 void Show(); //显示全部学生信息 void Back(); //学生信息反馈 void Readfile(const char* Filename);//读文件 void Writefile(const char* Filename);//写文件 };

添加学生信息：可录入学号、姓名、性别、语文、数学、英语等相关信息和成绩，并且由算法实现平均分、总分存入链表写入文件等的操作。

bool Teacher::Turnitin(int ID)// 学号查重 { DataBase* h = head->getNext(); while (h != NULL) { if (h->getID() == ID) { cout << "学号 " << ID << " 重复" << endl; cout << "请输入新的学号："; return false; } h = h->getNext(); } return true; } void Teacher::CreateDataBase() //添加新的学生信息 { system("cls"); DataBase* p = head->getNext(); cout << "\t添加学生数量："; int n = 0; cin >> n; for (int i = 0; i < n; i++) { p = new DataBase(); cout << "请输入第" << i + 1 << "位：" << endl; int ID = 0; string Name = " ", Sex = " "; double Chinese = 0, Math = 0, English = 0, Average = 0, Sum = 0; cout << " 学号:"; cin >> ID; while (1) { if (!Turnitin(ID)) { cin >> ID; } else { break; } } p->setID(ID); cout << " 姓名:"; cin >> Name; p->setName(Name); cout << " 性别:"; while (1) { cin >> Sex; if (Sex == "男" || Sex == "女") { break; } else { cout << "只能输入男/女\t请再次输入："; } } p->setSex(Sex); cout << " 语文:"; cin >> Chinese; p->setChinese(Chinese); cout << " 数学:"; cin >> Math; p->setMath(Math); cout << " 英语:"; cin >> English; p->setEnglish(English); p->getSum() = Chinese + Math + English; p->getAverage() = p->getSum() / 3.0; //newDataBase->next = temp->next;//头插法 //反馈信息 p->setNews("无");//无反馈信息 p->setSolute("无");//无解决方案 p->setNext(head->getNext()); head->setNext(p); Writefile("E://1C//学生管理//1.txt"); cout << "添加完成!" << endl; p = p->getNext(); } system("pause"); system("cls"); }

显示学生信息：可显示全部学生信息，并且每10个人会翻一下页及统计总人数。

void Teacher::Show()//显示全部信息 { system("cls"); cout << "学号\t姓名\t性别\t语文\t数学\t英语\t平均分\t总分" << endl; DataBase* o = head->getNext(); //遍历得到总人数 DataBase* h = head->getNext(); //遍历显示每个人的所有信息 int sd = 0, ss = 1; while (o != NULL) { sd = sd + 1; o = o->getNext(); } int i = 1; while (h != NULL) { if (ss > 0 && ss < 11) { ss = ss + 1; h->getSum() = h->getChinese() + h->getEnglish() + h->getMath(); h->getAverage() = h->getSum() / 3.0; cout << h->getID() << "\t" << h->getName() << "\t" << h->getSex() << "\t"; cout << fixed << setprecision(2) << h->getChinese() << "\t" << h->getMath() << "\t" << h->getEnglish() << "\t" << h->getAverage() << "\t" << h->getSum() << endl; } else { ss = 1; cout << "\t第[" << i++ << "/10人]页" << endl; system("pause"); system("cls"); cout << "学号\t姓名\t性别\t语文\t数学\t英语\t平均分\t总分" << endl; continue; } h = h->getNext(); } cout << "第[" << i++ << "/10人]页" << endl; cout << "参加考试共有【" << sd << "】个学生" << endl; system("pause"); }

修改学生信息：修改操作。

void Teacher::M1odify()//修改 { while (1) { system("cls"); DataBase* p1 = head->getNext();//按学号修改 DataBase* p2 = head->getNext();//修改学号 cout << "\t\t1、请输入学号：" << endl; cout << "\t\t2、修改学号" << endl; cout << "\t\t0、退出" << endl; cout << "\t选择："; int ch; cin >> ch; if (ch==1) //判断学号 { int ID1 = 0; cout << "请输入你的学号"; cin >> ID1; int q1 = 1; while (p1 != NULL)//遍历 { if (p1->getID() == ID1) { q1 = 0; cout << "学号\t姓名\t性别\t语文\t数学\t英语\t平均分\t总分" << endl; cout << p1->getID() << "\t" << p1->getName() << "\t" << p1->getSex() << "\t"; cout << fixed << setprecision(2) << p1->getChinese() << "\t" << p1->getMath() << "\t" << p1->getEnglish() << "\t" << p1->getAverage() << "\t" << p1->getSum() << endl; while (1) { //多次修改 cout << "(可修改姓名、性别、语文、数学、英语 按0可取消修改)" << endl; char ccc[100]; cout << "选择："; cin >> ccc; if (!strcmp(ccc, "姓名")) { cout << "修改为："; string name; cin >> name; p1->getName() = name; cout << "\t姓名修改成功！" << endl; } else if (!strcmp(ccc, "性别")) { cout << "修改为："; string sex; while (1) { cin >> sex; if (sex == "男" || sex == "女") { break; } else { cout << "只能输入男/女\t请再次输入："; } } p1->getSex() = sex; cout << "\t性别修改成功！" << endl; } else if (!strcmp(ccc, "语文")) { cout << "修改为："; double chin = 0; cin >> chin; p1->getChinese() = chin; p1->getSum() = chin + p1->getMath() + p1->getEnglish(); p1->getAverage() = p1->getSum() / 3.0; cout << "\t语文成绩修改成功！" << endl; } else if (!strcmp(ccc, "数学")) { cout << "修改为："; double ma = 0; cin >> ma; p1->getMath() = ma; p1->getSum() = ma + p1->getChinese() + p1->getEnglish(); p1->getAverage() = p1->getSum() / 3.0; cout << "\t数学成绩修改成功！" << endl; } else if (!strcmp(ccc, "英语")) { cout << "修改为："; double eng = 0; cin >> eng; p1->getEnglish() = eng; p1->getSum() = eng + p1->getMath() + p1->getChinese(); p1->getAverage() = p1->getSum() / 3.0; cout << "\t英语成绩修改成功！" << endl; } else if (!strcmp(ccc, "0")) { break; } } } p1 = p1->getNext(); } if(q1==1) { cout << "\t\t无此学号的学生！" << endl; system("pause"); } Writefile("E://1C//学生管理//1.txt"); } else if (ch==2) { cout << "选择要修改的学号："; int xu, xv = 0;//学号 cin >> xu; while (p2 != NULL) { if (p2->getID() == xu) { cout << "修改为："; int changexu; cin >> changexu; DataBase* q1 = head->getNext(); int y = 0; while (q1 != NULL) { if (q1->getID() == changexu) { y = 1; cout << "已有此学号的信息，不可修改！" << endl; break; } q1 = q1->getNext(); } if (y == 1)break; p2->getID() = changexu; cout << "\t修改成功！" << endl; Writefile("E://1C//学生管理//1.txt"); cout << "学号已经修改为" << p2->getID() << " 请妥善保管" << endl; break; } p2 = p2->getNext(); } if (p2 == NULL) { cout << "没有此学号" << endl; } system("pause"); } else if (ch==0) { break; } } }

查找学生信息：对学生查找。

void Teacher::Search() { while (1) { DataBase* pM = head->getNext(); //按姓名 DataBase* pN = head->getNext(); //按学号 system("cls"); cout << "\t\t1、按学号查找：" << endl; cout << "\t\t2、按姓名查找：" << endl; cout << "\t\t0、退出：" << endl; cout << "\t选择："; char choice[100] = { 0 }; gets_s(choice); if (!strcmp(choice, "2")) { cout << "请输入你的姓名：" << endl; string Name; cin >> Name; int cc = 0; cout << "序号\t学号\t姓名\t性别\t语文\t数学\t英语\t平均分\t总分" << endl; while (pM != NULL) { if (pM->getName() == Name) { cc++; cout << cc << "\t" << pM->getID() << "\t" << pM->getName() << "\t" << pM->getSex() << "\t"; cout << fixed << setprecision(2) << pM->getChinese() << "\t" << pM->getMath() << "\t" << pM->getEnglish() << "\t" << pM->getAverage() << "\t" << pM->getSum() << endl; } pM = pM->getNext(); } cout << "已查到以上[" << cc << "]个学生" << endl; system("pause"); } else if (!strcmp(choice, "1")) { cout << "请输入你的学号：" << endl; int ID; cin >> ID; int cc = 0; while (pN != NULL) { if (pN->getID() == ID) { cc++; cout << "序号\t学号\t姓名\t性别\t语文\t数学\t英语\t平均分\t总分" << endl; cout << cc << "\t" << pN->getID() << "\t" << pN->getName() << "\t" << pN->getSex() << "\t"; cout << fixed << setprecision(2) << pN->getChinese() << "\t" << pN->getMath() << "\t" << pN->getEnglish() << "\t" << pN->getAverage() << "\t" << pN->getSum() << endl; break; } pN = pN->getNext(); } if (pN == NULL) { cout << "没有学号为 " << ID << " 的学生" << endl; } system("pause"); } else if (!strcmp(choice, "0")) { break; } } }

删除学生信息：删除学生各个数据。

void Teacher::Delete() { while (1) { system("cls"); DataBase* p = head->getNext(); DataBase* q = head->getNext(); DataBase* pq = head; int ji = 0; cout << "学号\t姓名\t性别\t语文\t数学\t英语\t平均分\t总分" << endl; while (p != NULL) { ji++; cout << p->getID() << "\t" << p->getName() << "\t" << p->getSex() << "\t"; cout << fixed << setprecision(2) << p->getChinese() << "\t" << p->getMath() << "\t" << p->getEnglish() << "\t" << p->getAverage() << "\t" << p->getSum() << endl; p = p->getNext(); } cout << "\t\t共计【" << ji << "】名学生" << endl; cout << "\t\t输入学号便可删除( 0 退出)："; int dd = 0, pan = 1; cin >> dd; while (q != NULL) { if (dd == 0) { cout << "\t\t退出成功！" << endl; break; } if (q->getID() == dd) { pq->setNext(q->getNext()); delete q; q = NULL; cout << "\t\t删除成功！" << endl; Writefile("E://1C//学生管理//1.txt"); pan = 0; break; } pq = q; q = q->getNext(); } if (dd == 0)break; if (pan == 1) { cout << "\t\t未查询到此学号！" << endl; } system("pause"); } }

排序操作：可对语文、数学、英语等成绩单独操作，也可对平均分、总分排序。

void sortMachine(int i) //排序机,若只有一个人无法排序 { DataBase* p, * q, * temp; temp = head; p = temp->getNext()->getNext(); temp->getNext()->setNext(NULL); q = p->getNext(); while (1) { if (head->getNext() == NULL)break; if (i == 1)//语文 { while (temp->getNext() != NULL && temp->getNext()->getChinese() > p->getChinese()) temp = temp->getNext();//如果满足条件后移 } else if (i == 2)//数学 { while (temp->getNext() != NULL && temp->getNext()->getMath() > p->getMath()) temp = temp->getNext(); } else if (i == 3)//英语 { while (temp->getNext() != NULL && temp->getNext()->getEnglish() > p->getEnglish()) temp = temp->getNext(); } else if (i == 4)//平均分 { while (temp->getNext() != NULL && temp->getNext()->getAverage() > p->getAverage()) temp = temp->getNext(); } else if (i == 5)//总分 { while (temp->getNext() != NULL && temp->getNext()->getSum() > p->getSum()) temp = temp->getNext(); } p->setNext(temp->getNext()); temp->setNext(p);//temp一直指向p的下一个 temp = head;//从头遍历 p = q;//p后移一个 if (q == NULL)break; q = q->getNext(); } DataBase* o = head->getNext(); int c = 0; cout << "名次\t学号\t姓名\t性别\t语文\t数学\t英语\t平均分\t总分" << endl; while (o != NULL) { c++; cout << c << "\t" << o->getID() << "\t" << o->getName() << "\t" << o->getSex() << "\t"; cout << fixed << setprecision(2) << o->getChinese() << "\t" << o->getMath() << "\t" << o->getEnglish() << "\t" << o->getAverage() << "\t" << o->getSum() << endl; o = o->getNext(); } system("pause"); } void Teacher::Sort() //按成绩排序 { while (1) { system("cls"); DataBase* s1 = head->getNext(); DataBase* s2 = head; cout << "\t\t1、按语文排序" << endl; cout << "\t\t2、按数学排序" << endl; cout << "\t\t3、按英语排序" << endl; cout << "\t\t4、按平均分排序" << endl; cout << "\t\t5、按总成绩排序" << endl; cout << "\t\t0、退出" << endl; cout << "\t\t选择："; int chose = 0; cin >> chose; if (chose == 1) { sortMachine(chose); } else if (chose == 2) { sortMachine(chose); } else if (chose == 3) { sortMachine(chose); } else if (chose == 4) { sortMachine(chose); } else if (chose == 5) { sortMachine(chose); } else if (chose == 0) { break; } } }

学生信息反馈：学生端可发出信息教师端接收，并且可阅览反馈的问题，教师端可写下解决办法，传入学生端。

void Teacher::Back() { while (1) { system("cls"); DataBase* s9 = head->getNext(); DataBase* s6 = head->getNext(); int ssp = 0; cout << "序号\t学号\t姓名\t性别\t反馈信息\t解决方案" << endl; while (s9 != NULL) { if (s9->getNews() != "无") { cout << ++ssp << "\t" << s9->getID() << "\t" << s9->getName() << "\t" << s9->getSex() << "\t" << s9->getNews() << "\t\t" << s9->getSolute() << endl; } s9= s9->getNext(); } cout << "\t\t共计【" << ssp << "】条信息" << endl; if (ssp == 0) { cout << "\t\t无信息反馈!" << endl; system("pause"); break; } cout << "\t\t输入学号回复信息( 0 退出)："; int dd = 0 ; cin >> dd; if (dd == 0)break; while (s6 != NULL) { if (s6->getID() == dd) { break; } s6 = s6->getNext(); } if (s6 == NULL) { cout << "\t\t未查询到此学号！" << endl; system("pause"); continue; } cout << "\t\t请写回复信息："; cin >> s6->getSolute(); cout << "\t\t回复完毕！" << endl; Writefile("E://1C//学生管理//1.txt"); cout << "\t\t继续回复按1，退出按0" << endl; string ci = " "; while (1) { cout << "\t\t选择："; cin >> ci; if (ci == "0")break; if (ci == "1")break; cout << "\t\t无此选项！重选：" << endl; } if (ci == "0")break; system("pause"); } }
