File Encryption Filter File Encryption is the science of writing the contents of a file in a secret code. Your encryption program should work like a filter, reading the contents of one file, modifying the data into a code, and then writing the coded contents out to a second file. The second file will be a version of the first file, but written in a secret code. Although there are complex encryption techniques, in this assignment, you will use a simple one: Read the first file one character at a time, and add ten to the character code of each character before it is written to the second file. Write a class that performs the file encryption described above and demonstrate the class in a program.
