太简单了。。。。

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

 using namespace std;

 int main()
 {
     vector<string>words = { "zero","one","two","three","four","five","six","seven","eight","nine","ten" };
     string num;//不能用数字类型存储，会导致溢出的
     cin >> num;
     int sum = ;
     for (auto a : num)
         sum += a - '';
     num = to_string(sum);
     cout << words[num[] - ''];
     for (int i = ; i < num.length(); ++i)
         cout << " " << words[num[i] - ''];
     cout << endl;
     return ;
 }
