The text encryption/desencryption software should be used as a console application.These programs must use the same key for encryption and decryption.Encryption should be done by a simple replacement method.The source text for encryption must be drawn from the Input.txt file. Take the text arbitrary (for example, a breakdown from any book, the main, without non-censored expressions).The length of the original text is at least 200 ASCII characters.The text in the file must be placed in rows of no more than 80 characters in each.The encrypted text must be presented by the Output.txt file. The decrypted text from the Output.txt file must be presented by the Deshifr.txt file. The encryption of the code is done on the basis of the bit operation XOR.NOTE (this is my option of work, to perform in accordance with these conditions) - the key text in the encryption program must be prepared in advance by the file and drawn into the program from it.The key text in the decryption program is entered by the user from the keyboard.All the key symbols and the original (original) text are headlines.The way to set up the line of key symbols is the direct setting.The order was attached to the word-file, this is a methodology on this work.All the conditions of work were indicated above, there they are duplicated.
