1002 写出这个数 （20 分)

代码已经AC，写的有点笨拙，大佬们多指点哈

#include<stdio.h>

int main()
{

    int total=0;

    char j=0;

    while((j=getchar())!='\n')

        total=total+j-48;


    int a[4];

    int i=0;

    do

    {

        a[i]=total%10;

        i++;

        total=total/10;

    }while(total);

    char li[10][5] = {"ling","yi","er","san","si","wu","liu","qi","ba","jiu"};

    if(i!=1)

        {

            for(int m=i;m>1;m--)

                printf("%s ",li[a[m-1]]);

            printf("%s",li[a[0]]);

        }

    else

        printf("%s",li[a[0]]); 

    return 0;

}
