The file "original.txt" contains integer numbers in them. You are required to create another file, named "encoded.txt", from the original file.
Write a program "encoding.c" that reads every integer from the "original.txt" file and writes the integer and the sum of the digits of the
integer to the "encoded.txt" file.
The "encoded.txt" contains twice the number of integers compared to the "original.txt" file.
The contents of a sample "original.txt" and "encoded.txt" files are shown below.
