ACwing刷题笔记 1477.拼写正确

思路

首先将字符串中所有的数字全部取出转化成整数类型，然后累加求和，之后对求和结果转化成字符串，之后循环遍历字符串，将每一个字符对应的单词输出即可

代码

#include<iostream>
using namespace std;

int main()
{
    string n;
    cin>>n;
    
    int s = 0;
    for(auto c:n) s += c - '0';
    
    string str = to_string(s);
    
    char word[10][10] = {
        "zero","one","two","three","four",
        "five","six","seven","eight","nine",
    };
    
    // 输出第一个字母
    cout<<word[str[0] - '0'];
    
    for(int i = 1; i < str.size(); i++)
    {
        cout<<' '<<word[str[i] - '0'];
    }
    
    return 0;
    
}
