是不是我的输入处理出了问题,帮忙看一下：
int main()
{
	int i,j,k,p,q;
	int sum;

	//freopen("2997.in","r",stdin);
	while(scanf("%c",&ss[0])!=EOF)
	{
		sum=0;
		l=0;
		while(ss[l]!='\n')
		{
			if(ss[l]=='m'){ sum+=1000; l=0; }
			else if(ss[l]=='i' || ss[l]=='v' || ss[l]=='x' || ss[l]=='l' || ss[l]=='c' || ss[l]=='d')l++;
			ss[l]=getchar();
		}
		ss[l]='\0';
                  .................
          }
          return 0;
}
