How to use smart pointers in a singly linked list?

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. A singly linked list is a collection of nodes (elements), in which every node contains a data field and a link to the next node.

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.

Can a linked list be written with raw pointers?

For example, common vector implementations have one owning pointer and two non-owning 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.

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.

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.

How to print the third element of a singly linked list?

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. In other words, you can’t have random access to the singly linked list elements, like you can for example with an array.

When to use double pointer in linked list?

However,While I search on internet, I’ve realized that, the double pointer is used for creating linked list instead of a normal pointer.I mean, struct node **list , not struct node * list . I wonder why ?

Which is the root of a singly linked list?

A singly linked list is a collection of nodes (elements), in which every node contains a data field and a link to the next node. 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.

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 are pointers used in linked list in C + +?

Using ordinary C++ pointers, you’ve to take care of freeing any memory that was allocated. For instance, I created a simple linked list by creating a struct called node with a next pointer pointing to the next node or to nullptr.
