C2665： 没有重载函数可以转换所有参数类型
118行这里，我在参数列表这里传的是string类型的album_name，为什么不行，我对应的构造函数就是string

根据你截图提供的报错信息：在第118行 Album 类的构造函数中，需要传递一个 Singer* 类型的指针作为参数，而你传递的参数 &singer_name 的类型是 string*，因此类型不匹配，编译器会报错。
所以，你需要先创建一个 Singer 对象，然后将该对象的地址作为参数传递给 Album 构造函数，例如：
Singer* singer = new Singer(singer_name);
Album* album = new Album(album_name, singer);
Song song(song_name, album);
(*list).push_back(song);
代码使用了 new 关键字来动态创建 Singer 和 Album 对象，并使用它们在堆上分配的内存的地址来创建 Song 对象。注意，在程序结束时，需要释放这些内存，否则会出现内存泄漏。
