Pat A1005 Spell It Right

英语单词，不要用string进行存放，用char存放。For example:

 char str [10][10] = {"zero","one","two","three","four","five","six","seven","eight","nine"};

很简单的一道题。

#include <iostream>
#include <cstdio>
#include <cstring>

using namespace std;

int main(){
    char str [10][10] = {"zero","one","two","three","four","five","six","seven","eight","nine"};//不能用string

    char tempch;

    int sum = 0;
    tempch = getchar();

    while(tempch != '\n'){
        sum = sum + tempch - '0';
        tempch = getchar();
    }

    int in[105];

    int len = 0;
    if(sum == 0){
        in[len ++] = 0;
    }



    while(sum != 0){
        in[len ++] = sum % 10;
        sum = sum / 10;
    }
    for(int i = len - 1;i >= 0;i --){
        printf("%s",str[in[i]]);
        if(i != 0) {
            printf(" ");
        }
    }

    printf("\n");
    return 0;
}
