#include<stdio.h>
char *ch=new char[30];
long int input()
{
     long int i,sum=0;
     scanf("%s",ch);
	 if(ch[0]=='0') return 0;
	 for(i=0;ch[i]!=0;i++)
		 sum+=ch[i]-'0';

	 return sum;
}
int main()
{
	long int i,j,k;long int sum;
	
	i=input();
	while(i)
	{ 
		sum=0;
		while(i>0){ 
		   while(i>0)
		   {
           j=i%10;//printf("%ld\n",i);
           i=i/10;
		   sum+=j;
		   }
		   if(sum>=10) {i=sum;sum=0;}
		}
		
		printf("%ld\n",sum);
		i=input();
	}
	return 0;
	
}
看看我的,可以参考一下,写得不好不要见怪,数组30就可以了
