Circular Linked-List C++

This is a simple implementation of a circular linked-list in C++.

Features

• Add a new node at beginning of list.
• Add a new node at end of list.
• Add a new node after a data.
• Add a new node before a data.
• Add a new node after a index.
• Add a new node before a index.
• Get the index of a data.
• Get the data of a index.
• Check if list is empty.
• Check if list contains a data.
• Check if list contains a index.
• Get the size of list.
• Print the list.
• Print the list in reverse order.
• Reverse the linkedlist (iterative function)
• Recursive function to reverse the linkedlist.
• Delete a node at beginning of list.
• Delete a node at end of list.
• Delete a node after a data.
• Delete a node before a data.
• Delete a node after a index.
• Delete a node before a index.
• Delete a node by data.
• Delete a node by index.
• Delete all nodes by data.
• Delete all nodes by index.
• Delete all nodes.
• Delete the list.
• Clear the list.
• Copy the list.
