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:

• 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()
