Can a linked list be written with smart pointers?
Writing a linked-list class in C++ with raw pointers can be a useful academic exercise. Writing a linked-list class in C++ with smart pointers is a pointless academic exercise. Using any of these two self-made things in production code is almost automatically wrong.
Do you use smart pointers for low level data structures?
You do not use smart pointers for low-level data structures. You use smart pointers for high-level program logic.
When do you use smart pointers in C + +?
You use smart pointers for high-level program logic. As far as low-level data structures are concerned, you use a standard container class from the C++ standard library, like std::list [*], which solves all your memory-management problems anyway, without using any smart pointers internally.
How to implement a singly linked list in C + + 17?
In this tutorial, I will show you how to implement a singly linked list data structure in C++17 with smart pointers. This is also useful as an exercise in learning about how you can use smart pointers instead of raw pointers to manage the memory of the list elements.
Which is the first node in a singly linked list?
The first node of a singly linked list is usually named head or root. The last element of the list is usually named tail and his next field links to nothing. An interesting property of the singly linked list is that, in order to visit a certain node, you will need to pass through all the previous list nodes until the searched one.
Which is an interesting property of a singly linked list?
An interesting property of the singly linked list is that, in order to visit a certain node, you will need to pass through all the previous list nodes until the searched one. For example, if you want to print the third element of a singly linked list, you will need to start at the list head and pass through the first and second nodes.
