如何使用std :: transform和模板

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

int main() {
    std::vector<int> v {1, 2, 3, 4, 5};
    std::vector<std::string> result(v.size());

    std::transform(v.begin(), v.end(), result.begin(), [](int i) {
        return std::to_string(i);
    });

    for (const auto& s : result) {
        std::cout << s << " ";
    }

    return 0;
}
