Templates and nested classes/structures?

That's because node is a dependent type. You need to write the signature as follows (note that I have broken it into 2 lines for clarity).

You need to tell the compiler that node is a type using the keyword typename. Otherwise it will think node as a static variable in class list. Add typename whenever you use node as a type in your implementation of list.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
