其中8,4代表有几组测试样例，程序输入0结束，下面是我的程序

#include <stdio.h>
#include <string.h>

struct DATA
{
    char ID[13];
    char IP[16];
    char c;
} data[20];


struct MJ
{
    char mid[13];
    char jid[13];
} mj[10];
char tmp[13];
int n,i,m,k,j;
int main(void)
{
    while (1)
    {
        scanf("%d",&n);
        if (n==0)
            break;
        for (i=0;i<n;i++)
        {
            scanf("%s%s",data[i].ID,data[i].IP);
            data[i].c=0;
        }
        k=0;
        while (1)
        {
            m=-1;
            for (i=0;i<n;i++)
            {
                if (data[i].c==0)
                {
                    if (m==-1)
                    {
                        data[i].c=1;
                        m=i;
                    }
                    else
                    {
                        if (strcmp(data[m].IP,data[i].IP)==0)
                        {
                            data[i].c=1;
                            strcpy(mj[k].mid,data[m].ID);
                            strcpy(mj[k].jid,data[i].ID);
                            k++;
                            break;
                        }
                    }
                }
            }
            if (i>=n) break;
        }
        for (i=0;i<k-1;i++)
        {
            for (j=i+1;j<k;j++)
            {
                if (strcmp(mj[i].mid,mj[j].mid)==1)
                {
                    strcpy(tmp,mj[i].mid);strcpy(mj[i].mid,mj[j].mid);strcpy(mj[j].mid,tmp);
                    strcpy(tmp,mj[i].jid);strcpy(mj[i].jid,mj[j].jid);strcpy(mj[j].jid,tmp);
                }
            }
        }
        for (i=0;i<k;i++)
        {
            printf("%s is the MaJia of %s\n",mj[i].jid,mj[i].mid);
        }
        printf("\n");
    }
}

我的程序中总是只能测一次，比如第一个输入8，下面输入8组ID,IP后就自动得出结果，也没有遇0结束，大家帮忙看看啊，该怎么改改这个程序？谢谢大家啦！！
