运行这段代码，每次输入都为2，结果color 后是空的？如果我改color为int型运行正确了，这是为什么？

#include
#include
using namespace std;
class ABC
{
private:
    string label="0";
    int rating=0;
protected:
    string Label(){return label;}   
    int Rating(){return rating;}
public:
    ABC(string la="null",int ra=-1):label(la),rating(ra){}   
    virtual void ViewABC()=0;   

};

class lacksDMA:public ABC
{
private:
    string color;
public:
    lacksDMA(string co="null",string la="null",int ra=-1):ABC(la,ra),color(co){}
    virtual void ViewABC()
    {
        cout<<"\n\nLabel:"<>ratemp;




        cout<<"Color is :";
        getline(cin,cotemp);
        pDMA[i]=new lacksDMA(cotemp,latemp,ratemp);


        while(cin.get()!='\n')
            continue;

    }
    for(int i=0; iViewABC();
    }

}
