C++ Program to learn about: Encryption/Decryption with Password Generator to display decrypted content

The 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. Once the data is encrypted, the program should generate a password file to be used to decrypt the file in the future. The password should be saved into a third file. To verify that the program works, there should be a decryption option that reads the contents of the second file, restore the data to its original state, and display the file contents on screen. It should also require the user to enter the password, comparing the inputted password to the password stored in the third file created ealier. If it is the correct password, the content of the decryption file will be on the screen.
