a) A simple encryption of a character A can be performed by exclusive-ORing A with some key K to produce the encrypted value E. The original value A can be recovered by exclusive-ORing again with the same key.
Write a c/c++ program that encrypts a character from the list [A...Za...z]. The key can be any ASCII character in the range [A...Za...z]. Your program should request both a key and the character to be encrypted. The output should be the character and its encrypted value.
Print appropriate error messages if the user enters something other than an expected value. You must ensure that the encrypted value is also a printable ASCII character (hint: this may require some operations in addition to the exclusive-OR).
b) Write a companion program to decrypt the values you encrypt with the above program.
Write a program that opens two text files for input and one for output. The program should concatenate the corresponding lines of the input files.
Your proof must explicitly and clearly indicate the base case you prove, the inductive case you prove and what the inductive hypothesis provides in the proof.
