AHC Programming Question

I’m working on an animal game in C++; I want you to complete the codes by following the comments inthe codes.
I will provide you the main code.
Topics we talk about these topics so far to complete this program: classes ( private vs public ) ,
constructors, destructors, new/ delete and heap vs stack data.
And we talk about this in the class can you send an explanation and tutorial links about this example:
node < int > n;
Node < string > n2;
node < node < int >> n3;

Here is the code main which I will provide to you:
