1005. Spell It Right (20)

1.主要是string的位操作，string的每一位都是一个char

//#include<string>//#include <iomanip>#include<vector>#include <algorithm>//#include<stack>#include<set>#include<queue>#include<map>//#include<unordered_set>//#include<unordered_map>//#include <sstream>//#include "func.h"//#include <list>#include<stdio.h>#include<iostream>#include<string>#include<memory.h>using namespace std;int main(void) {string str;cin >> str;int sum = 0;for (int i = 0; i < str.size(); i++){sum += str[i] - '0';//直接进行各位的累加}string int2Str[10] = { "zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine" };str = "";string ans = "";if (sum == 0) ans = "zero";while (sum != 0){char c = sum % 10 + '0';str = c + str;sum /= 10;}for (int i = 0; i < str.size(); i++){ans += int2Str[str[i] - '0'];if (i != str.size() - 1)ans += " ";}cout << ans << endl;return 0;}
