Sir,please help me out with the code of this question. Write an interactive C program that will encode or decode multiple lines of text. Store the encoded text within a data file, so that it can be retrieved and decoded at any time. The program should include the following features: (a) Enter text from the keyboard, encode the text and store the encoded text in a data file. (b) Retrieve the encoded text and display it in its encoded form. (c) Retrieve the encoded text, decode it and then display the decoded text. (d) End the computation. Test the program using several lines of text of your choice.

In cryptography, you could often break the algorithm if you know what was the original (plain) text that was encoded into the current ciphertext. This is called the plain text attack. In this simple problem, we illustrate the plain text attack on a simple substitution cipher encryption, where you know each letter has been substituted with a different letter from the alphabet but you don’t know what that letter is. You are given the cipherText as the input string to the function getwordSets(). You know that a plain text "AMMUNITION" occurs somewhere in this cipher text. Now, you have to find out which sets of characters corresponds to the encrypted form of the "AMMUNITION". You can assume that the encryption follows simple substitution only. [Hint: You could use the pattern in the "AMMUNITION" like MM occurring twice together to identify this]

1) There is a singing competition for children going to be conducted at a local club. Parents have been asked to arrive at least an hour before and register their children’s names with the Program Manager. Whenever a participant registers, the Program Manager has to position the name of the person in a list in alphabet order. Write a program to help the Program Manager do this by placing the name in the right place each time the Program Manger enters a name. The Logic should be written in Data Structures?
