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, you should develop a simple one of your own. For example, you could read the first file one character at a time and add 10 to the character code of each character before it is written to the second file
