题目大意：给一个非负正数N，计算N的每一位相加的和，然后输出和的每一位的英文读音～

分析：1、求出每一位相加的和sum  2、将sum转换为string s  3、将string s的每一位输出对应的英文读音～

#include 
using namespace std;
int main() {
    string a;
    cin >> a;
    int sum = 0;
    for (int i = 0; i < a.length(); i++)
        sum += (a[i] - '0');
    string s = to_string(sum);
    string arr[10] = {"zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine"};
    cout << arr[s[0] - '0'];
    for (int i = 1; i < s.length(); i++)
        cout << " " << arr[s[i] - '0'];
    return 0;
}
