如何在c++中将std::set转换为std::map

#include <iostream>
#include <set>
#include <map>

int main() {
    std::set<int> mySet = {1, 2, 3, 4, 5};
    std::map<int, int> myMap;

    for (auto it = mySet.begin(); it != mySet.end(); ++it) {
        myMap[*it] = 0; // 设置默认值为0
    }

    // 输出转换后的std::map
    for (const auto& pair : myMap) {
        std::cout << pair.first << ": " << pair.second << std::endl;
    }

    return 0;
}
