    ifstream inside("movies.txt");
    while (!inside.eof())

        getline(inside, ptr[i].moviename);
        inside >> ptr[i].yearreleased;
        getline(inside, ptr[i].genre);
        inside >> ptr[i].duration.hours;
        inside >> ptr[i].duration.minutes;
        getline(inside, ptr[i].actorname1);
        getline(inside, ptr[i].actorname2);
        inside >> ptr[i].yearreleased;
        i++;
    }
}
int main()
{
    moviedata *md = new moviedata;
    readmoviedata(md);
    delete md;
    return 0;
}

谁能告诉我我在函数读取电影数据上做错了什么$当调用函数 readmoviedata 时逐行运行时$ 出现黑色网格，光标闪烁，没有其他

问题是您正在创建结构类型的一个指针变量。

moviedata *md = new moviedata;

并且您将此变量视为数组。

 ptr[i].yearreleased;
