在for_each中访问地图的索引

#include <iostream>
#include <vector>
#include <algorithm>

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

    std::for_each(map.begin(), map.end(), [](int element) {
        int index = std::distance(map.begin(), std::find(map.begin(), map.end(), element));
        std::cout << "Index: " << index << ", Element: " << element << std::endl;
    });

    return 0;
}

Index: 0, Element: 1
Index: 1, Element: 2
Index: 2, Element: 3
Index: 3, Element: 4
Index: 4, Element: 5
