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()
