}

cin>>service;
cin>>bookname;

cout<<"你所登记的新书为："<<endl;
bkcList[bkcCount].showMe();
bkcCount++;
}while(strcmp(service,"exit")!=0);
}

void BookCard::showMe()
{
for(int j(0);j<=bkcCount;j++)
cout<<" 书名: "<<bkcList[j].m_sBookName<<endl;;
}

现在那个是小问题，关键是：比如第一次输入‘111’，第二次输入‘222’，再第一次输入的就丢失了。希望高手帮我，谢谢了

已改好，谢谢了。
