今天我太闲了，就模仿zeng9999jian做了一个百家姓。
做完感觉没啥用...............

    cout<<"请输入姓氏的拼音，如zhou（周），";
    cout<<"如果有这个姓氏，则输出true，反之则输出false"<<endl;
    cout<<"因为这个只有46个姓氏，所以可能不准"<<endl;
    cout<<"退出请输入“退出”"<<endl; 
    while(1){
        cin>>b;
        if(b=="退出")return 0; 
        bool x=true;

                cout<<"true";
                break;
