Write a C++ program to insert or delete characters in a buffer. You need to develop an abstract data type for a buffer in the text editor program that implements the following operations using linked list not using stack:

Create an empty buffer createBuffer()

Insert a character at the cursor position

insert(char c)

Get the character at the cursor position char get()

Delete and return the character at the cursor char delete()

Move the cursor k position to the left void left (int k)

Move the cursor k positions to the right void right(int k)

Return the number of characters in the buffer int size()
