- Others Question: 1) Give a description of your approach in detail. What steps will you use to convert a character string to a numeric value to seed the random number generator. Do not describe code. Answer: Minimum 200-word description. Are there any weaknesses in your method? Explain. Answer: Minimum 150-word description. 2) Implement the approach in Java Script. Answer: note you don’t have to dump the entire code here. Show the new function you have written and then the code snippets of where in encrypt and decrypt it exists.Allocate memory for a string of 15 characters and assign “new string” to it. Print the string. Now, try following options: Change the string to “another string” using assignment operator. Change the string to “another string” using strcpy. Note down whether the address changes in both cases or not.Caesars Cypher in C programming language How do you program an encryption and decryption for a Caesars Cypher that covers all the possible ASCII characters? In this there should be a shift over K = 5 but the example below is K = 3. This should result in actual character and not the control ASCII represenations. For example: >>> $ encrypt(I have a key)N%mf{j%f%pj~>>> $ encrypt(see me at 3)xjj%rj%fy%8>>> $ decrpyt(|jfw%ns%gqzj)wear in blue Assume that the text parsing method has been succesful and it's the encryption/decryption of the char array that needs to be factored. Formula Encryption -> C = E(k, P) = (P + k) (mod 26) Decryption -> P = D(k, C) = (C - k) (mod 26) Where k = 5

For 'proof-of-concept', a partial implementation is good enough. Rather than translating every Morse Code character, just a handful will do. Use the letters from your first name, all upper case. Note that Morse Code characters consist of one or more dots or dashes. For example, the Morse Code for 'S' is '...' and for 'O' is '---'. See https://morsecode.scphillips.com/translator.html (Links to an external site.) for more info on Morse code. Be sure to include header comments in each step! Step 1 In this step, you'll set up the logic to convert letters to Morse code. Create an application that asks the user to enter an upper case letter.Use an if-elif construct to determine which letter was entered and store the appropriate Morse code string in a variable. If there is no match, set the variable to "Unknown".As an example, the Morse code for the letter 'S' is represented using a string of three periods, "...", for dot…given a string, capitalize the letters that occupy even indexes and odd indexes separately JavaScript.
