杭州电子科技大学ACM网站上的1047题无法提交成功, 题目是高精度加法。题目如下
Integer Inquiry
Time Limit: 2000/1000 MS (Java/Others)    Memory Limit: 65536/32768 K (Java/Others)
Total Submission(s): 4555    Accepted Submission(s): 1090


Problem Description
One of the first users of BIT's new supercomputer was Chip Diller. He extended his exploration of powers of 3 to go from 0 to 333 and he explored taking various sums of those numbers.
``This supercomputer is great,'' remarked Chip. ``I only wish Timothy were here to see these results.'' (Chip moved to a new apartment, once one became available on the third floor of the Lemon Sky apartments on Third Street.)

 

Input
The input will consist of at most 100 lines of text, each of which contains a single VeryLongInteger. Each VeryLongInteger will be 100 or fewer characters in length, and will only contain digits (no VeryLongInteger will be negative).

The final input line will contain a single zero on a line by itself.

 

Output
Your program should output the sum of the VeryLongIntegers given in the input.


This problem contains multiple test cases!

The first line of a multiple input is an integer N, then a blank line followed by N input blocks. Each input block is in the format indicated in the problem description. There is a blank line between input blocks.

The output format consists of N output blocks. There is a blank line between output blocks.

我该啦，但是还是错啦。。。上面我测试数据：
#include<iostream>
using namespace std;
#define T 110
char a[110][110];
int d[110],p[T];
int k,i,j,R;
int main()
{
    freopen("D:\\in.txt","r",stdin);
    scanf("%d",&R);
    while(R--)
    {
        k=0;
        getchar();
        while(1)
        {
           scanf("%s",a[++k]);
           if(strcmp(a[k],"0")==0)  break;
        }
        int max_len=0;
        for(i=1;i<k;i++)
        {
             d[i]=strlen(a[i]);
             if(d[i]>max_len)
                  max_len=d[i];

        }
        for(i=1;i<k;i++)
        {
            for(j=0;j<d[i];j++)
                a[i][j]-='0';
        }
        memset(p,0,sizeof(p));
        for(i=max_len-1;i>=0;i--)
        {
            for(j=1;j<k;j++)
            {
                if(d[j]>0)
                {
                    p[i]+=a[j][--d[j]];
                }
            }
        }
        for(i=max_len-1;i>0;i--)
        {
            p[i-1]+=p[i]/10;
            p[i]=p[i]%10;
        }
        if(p[0]>=10)
        {
            printf("%d",p[0]/10);
            p[0]=p[0]%10;
        }
        for(i=0;i<=max_len-1;i++)
        {
            printf("%d",p[i]);
        }
        printf("\n");
        if(R!=0) printf("\n");
    }
    return 0;

貌似还是有溢出，R 的值被改写了。
你把 while 最后的 if(R!=0) printf("\n"); 改成 if(R!=0) printf("%d\n", R); 就能看到

你试试用你上面都是 9 的那组数据，能看到 R 的值变得很古怪
