Given a non-negative integer N, your task is to compute the sum of all the digits of N, and output every digit of the sum in English.
给定一个非负整数N,您的任务是计算N的所有数字的和,并以英语输出和的每一个数字。
Input Specification:
Each input file contains one test case. Each case occupies one line which contains an N (≤10100).
Output Specification:
For each test case, output in one line the digits of the sum in English words. There must be one space between two consecutive words, but no extra space at the end of a line.
Sample Input:
12345
Sample Output:
one five
#include<iostream>
using namespace std;
int main()
{
string a;
cin>>a;//把数字以字符串形式输入
int sum=0;
for(int i=0;i<a.length();i++)
sum+=(a[i]-'0');//把字符串变成数字后每位相加,此时sum为数字
string s=to_string(sum);//把sum变成字符串
string arr[10]={"zero","one","two","three","four","five","six","seven","eight","nine"};
//定义一个字符串数组
cout<<arr[s[0]-'0'];//进行演示--字符串15,1变成数字对应arr[1]=0;
for(int i=1;i<s.length();i++)
cout<<" "<<arr[s[i]-'0'];//最后一个字母后面不能有空格
}
start
字符串输入--(a[i]-'0')-->数字相加得到数字sum--string s=to_string(sum)-->
把sum再变成字符串--(s[i]-'0')--->sum再变成数字---arr[s[i]-'0']--->
对应arr中的字符串(英文字母)
