字符串库的复制方法对我的构造函数不起作用

Question

当我在main中调用显示功能时，它不会输出我已初始化我的对象的字符串。

class Grupa{
    char indicativ;
    string team[4];
public:
    Grupa(char ind,string teams[4])
    {
        indicativ=ind;
        copy(team,team+4,teams);//here it doesn't copy the string correctly!
    }
void display()
{
    int i=0;
    cout<<"Grupa "<<indicativ<<":"<<endl;
    for(i=0;i<4;i++)
    {
        cout<<i+1<<". "<<team[i]<<endl;
    }
}

};

你的副本方向错误：

class Grupa{
    char indicativ;
    string team[4];
public:
    Grupa(char ind,string teams[4])
    {
        indicativ=ind;
        std::copy(teams,teams+4,team);
                              // ^ destination 
    }
};
