Question
Transcribed Image Text:you are going to write a program in C++ that implements a doubly linked list.
The data must be read from the files, and you can put the file names in your program.
Letters.txt contains 26 English Letters:
A
B
C
D
***
N
Sequence.txt contains a list of numbers.
3,-3,19,-19,18,1,-2,3,-18,17,1,-3,-13,14
You need to
1. Create a doubly linked list by reading the 26 letters from Letters.txt.
2. Sequence.txt file contains a sequence of relative letter positions. The initial position is at the
beginning of the list which is 'A'. The first number in the sequence is '3'. So, the current
position will move forward for three steps. Then the first letter to output is 'D' and now the
current position is at 'D' as well. The second number in the sequence is '-3'. Then the second
letter to output is the third element backward from the current position which is 'A'. You |
need to output all letters indicated in sequence.txt
Your need to
1. Create a doubly linked list
2. Implement putitem() method and use this method to create the doubly linked list
3. Correctly read the files and interpret the information
4. Print out the letters
