How can I create a list in C++? I need it to create a linked list. How would I go about doing that? Are there good tutorials or examples I could follow?
This question is related to
c++
list
stl
linked-list
If you are going to use std::list, you need to pass a type parameter:
list<int> intList;
list<int>* intListPtr = new list<int>;
If you want to know how lists work, I recommending googling for some C/C++ tutorials to gain an understanding of that subject. Next step would then be learning enough C++ to create a list class, and finally a list template class.
If you have more questions, ask back here.
I'm guessing this is a homework question, so you probably want to go here. It has a tutorial explaining linked lists, gives good pseudocode and also has a C++ implementation you can download.
I'd recommend reading through the explanation and understanding the pseudocode before blindly using the implementation. This is a topic that you really should understand in depth if you want to continue on in CS.
Why reinvent the wheel. Just use the STL list container.
#include <list>
// in some function, you now do...
std::list<int> mylist; // integer list
We are already in 21st century!! Don't try to implement the already existing data structures. Try to use the existing data structures.
Use STL or Boost library

You should really use the standard List class. Unless, of course, this is a homework question, or you want to know how lists are implemented by STL.
You'll find plenty of simple tutorials via google, like this one. If you want to know how linked lists work "under the hood", try searching for C list examples/tutorials rather than C++.
Create list using C++ templates
i.e
template <class T> struct Node
{
T data;
Node * next;
};
template <class T> class List
{
Node<T> *head,*tail;
public:
void push(T const&); // push element
void pop(); // pop element
bool empty() // return true if empty.
};
Then you can write the code like:
List<MyClass>;
The type T is not dynamic in run time.It is only for the compile time.
