pat（B） 1002. 写出这个数

代码：

#include<cstdio>
#include<cstring>
using namespace std;

char s[105];
int a[100];
char num[12][100];

int main()
{
    strcpy(num[0],"ling");
    strcpy(num[1],"yi");
    strcpy(num[2],"er");
    strcpy(num[3],"san");
    strcpy(num[4],"si");
    strcpy(num[5],"wu");
    strcpy(num[6],"liu");
    strcpy(num[7],"qi");
    strcpy(num[8],"ba");
    strcpy(num[9],"jiu");
    while(scanf("%s",s)==1)
    {
        int len=strlen(s);
        int ans=0;
        for(int i=0; i<len; i++)
        {
            ans+=(s[i]-'0');
        }
        if(ans==0)
            printf("ling\n");
        int i=0;
        while(ans>0)
        {
            int r=ans%10;
            a[i++]=r;
            ans=ans/10;
        }
        for(int j=i-1; j>=0; j--)
        {
            if(j==0)
                printf("%s\n",num[a[j]]);
            else
                printf("%s ",num[a[j]]);
        }
    }
