```c++ #include <iostream> #include <string> #include <vector> using namespace std; struct LearningContent { string title; string description; int priority; }; class LearningManagementSystem { private: vector<LearningContent> learningContents; public: void addLearningContent(string title, string description, int priority) { LearningContent content; content.title = title; content.description = description; content.priority = priority; learningContents.push_back(content); } void displayLearningContents() { for (const auto& content : learningContents) { cout << "Title: " << content.title << endl; cout << "Description: " << content.description << endl; cout << "Priority: " << content.priority << endl; cout << "---------------------------" << endl; } } void editLearningContent(int index, string title, string description, int priority) { if (index >= 0 && index < learningContents.size()) { learningContents[index].title = title; learningContents[index].description = description; learningContents[index].priority = priority; } else { cout << "Invalid index" << endl; } } void sortLearningContents() { sort(learningContents.begin(), learningContents.end(), [](const LearningContent& a, const LearningContent& b) { return a.priority < b.priority; }); } void searchLearningContent(string keyword) { for (const auto& content : learningContents) { if (content.title.find(keyword) != string::npos || content.description.find(keyword) != string::npos) { cout << "Title: " << content.title << endl; cout << "Description: " << content.description << endl; cout << "Priority: " << content.priority << endl; cout << "---------------------------" << endl; } } } }; int main() { LearningManagementSystem lms; lms.addLearningContent("C++ Programming", "Learn the basics of C++ programming language", 3); lms.addLearningContent("Data Structures", "Study different data structures and their implementation", 2); lms.addLearningContent("Algorithms", "Learn about various algorithms and their complexities", 1); cout << "Learning Contents:" << endl; lms.displayLearningContents(); lms.editLearningContent(0, "C++ Programming Basics", "Learn the fundamentals of C++ programming language", 4); lms.sortLearningContents(); cout << "Sorted Learning Contents:" << endl; lms.displayLearningContents(); cout << "Search Results for 'Algorithms':" << endl; lms.searchLearningContent("Algorithms"); return 0; } ``` 这是一个简单的学习管理系统的示例，其中包括添加学习内容，显示学习内容，编辑学习内容，排序学习内容和搜索学习内容等功能。用户可以根据自己的需要使用这些功能来管理和规划自己的学习。 [2024-07-01 21:17:35 | AI写代码神器 | 2028点数解答]
