以下是一个使用 C++ 实现学生课程选课系统的基本框架代码： ```cpp #include <iostream> #include <string> #include <vector> // 课程类 class Course { public: std::string name; std::string teacher; std::string time; std::string location; Course(std::string n, std::string t, std::string ti, std::string l) { name = n; teacher = t; time = ti; location = l; } }; // 学生类 class Student { public: std::string name; std::vector<Course> selectedCourses; Student(std::string n) { name = n; } }; // 添加新课程 void addCourse(std::vector<Course>& courses, std::string name, std::string teacher, std::string time, std::string location) { courses.emplace_back(Course(name, teacher, time, location)); } // 学生选课 void studentSelectCourse(Student& student, Course course) { student.selectedCourses.push_back(course); } // 学生退课 void studentDropCourse(Student& student, Course course) { for (auto it = student.selectedCourses.begin(); it!= student.selectedCourses.end(); ++it) { if (it->name == course.name) { student.selectedCourses.erase(it); break; } } } // 显示课程选课情况 void displayCourseSelection(const std::vector<Student>& students, const Course& course) { std::cout << "课程: " << course.name << " 选课学生: "; for (const auto& student : students) { for (const auto& selectedCourse : student.selectedCourses) { if (selectedCourse.name == course.name) { std::cout << student.name << " "; break; } } } std::cout << "上课时间: " << course.time << " 地点: " << course.location << std::endl; } // 修改课程信息 void modifyCourse(Course& course, std::string newName, std::string newTeacher, std::string newTime, std::string newLocation) { course.name = newName; course.teacher = newTeacher; course.time = newTime; course.location = newLocation; } // 删除课程信息 void deleteCourse(std::vector<Course>& courses, Course course) { for (auto it = courses.begin(); it!= courses.end(); ++it) { if (it->name == course.name) { courses.erase(it); break; } } } int main() { std::vector<Course> courses; std::vector<Student> students; // 示例操作 addCourse(courses, "数学", "张老师", "周一 8:00", "教学楼 101"); Student s1("小明"); studentSelectCourse(s1, courses[0]); displayCourseSelection(students, courses[0]); return 0; } ``` 以下是三个改进建议： 1. 增加错误处理机制，例如在添加课程或学生选课等操作时，处理输入错误的情况。 2. 优化数据存储，例如使用数据库来存储课程和学生信息，提高数据管理的效率和可靠性。 3. 增加用户界面，使用户能够更方便地与系统进行交互，而不仅仅是通过代码中的函数调用。 [2024-12-22 19:46:02 | AI写代码神器 | 820点数解答]
