4. Suppose, you are trying to encrypt a string for security purpose. Write a program that can take a string from the user and then create a function that can replace all the vowels to its immediate next letters. Print the modified string. Don't use any Library function. Use this function: void str_modify(char "p); Example: Input string: i love Bangladesh. Modified string: j lpvf Bbnglbdfsh

// Task 2 // For this function, you must build a string that when printed,// will output the entire binary representation of the integer x,// no matter how many bits an integer is.

8.In this exercise you will create a program that will be used in a digital library to format and sort journal entries based on the authors last name. Each entry has room to store only the last name of the author. Begin by removing the first name "Isaac" from the string variable journal_entry_1 by using the string function erase. Do not forget to also remove the whitespace so that the string variable journal_entry_1 will then contain the string "Newton" with no whitespaces. The journal entries should be sorted alphabetically based on the authors last name. For example, the last name "Brown" should come before the last name "Davis" Create an if statement so that if the last name contained within journal_entry_2 is alphabetically less than the last name contained within journal_entry_1, then the string values are swapped using the string function swap. You may use either of the comparison operators < > in the if statement but remember that following ASCII, "A" is lexicographically…
2. Caesar Cipher Create a function that takes two arguments (text, key) and returns a new encrypted text using the key. For example, if the input is "a" and the key is 1, it should move that letter 1 step in alphabetic order so the output would be "b". Examples: caesar_cipher("hello", 5) "mjqqt" caesar_cipher("hello world", 1)"ifmmp xpsme" caesar_cipher("a", 2)→ "c" Notes: The input is only letters and spaces; no special characters. What is Caesar cipher? Method in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet. The method is named after Julius Caesar, who used it in his private correspondence.

Write a function encrypt that receives a message with a string or character vector and returns the message that is encrypted. This function returns the message concealed in the input string that is the first letter of each word in the string (or char vector) and returns a string that contains the first letter of each word in the input string. >> string = ‘This is the third question of final exam’; >> m = encrypt(string) m = ‘Tittqofe’ ( this question's program language is matlab )

In Python, write a function named cipher that takes a string. The function returns that string in a ciphered form by using the ord of the first letter of the string to cipher each letter including the first letter. Hence for abc, use the ord of 'a', and add it to the ord of 'a' and convert that result to a character use the chr function. This character should be concatenated to the same action on the letter b and so on. Hence the function returns: chr(ord('a')+ord('a')) + chr(ord('a')+ord('b')) + chr(ord('a')+ord('c')).Obviously you need a loop to iterate on each letter. Write another function to decipher (do the opposite of the previous function), given a string and returns the deciphered string. Obviously, the first letter's ord is halved to find the first letter, and that value is used to decipher the remaining letters. From main, write code to get a string, as input, then call the cipher function and print its output.Then call the decipher function and display its output. The…

Suppose you are using a library function capcons which takes a string and makes all the consonants into capital letters while leaving the vowels unchanged. It requires there to not be any ys in the string because it can't tell if they are vowels or consonants. What type would you expect for the string argument? (If there are multiple possibilities, choose the best fit for this function) A. char * B. char ** C. const char * D. const char ** E. String
You will write a function that can be used to decrypt Dan’s encrypted text. You will be given an open file that contains an encrypted passage from one of the books, and the name of a file containing a wordlist of English words. You need to discover the shift value to use (0-25) in order to decrypt the text. A correct shift value is one that leads to the maximum number of words being found in the English list of words. To find the words in the encrypted text, you must call split(). For a given shift value, convert all letters to lowercase, then try to find each word in the English wordlist. Do not remove any punctuation or symbols from the word: for example, if the word is hello!, then that is the exact string, including exclamation mark, that you should try to find in the English wordlist. Your function should return a string where all letters are in lowercase, and all other characters (newlines, spaces, punctuation, etc.) are retained. Input In each test case, we will call your…
Write a function encrypt that receives a message with a string or character vector and returns the message that is encrypted. This function returns the message concealed in the input string that is the first letter of each word in the string (or char vector) and returns a string that contains the first letter of each word in the input string. >> string = ‘This is the first question of quiz’; >> m = encrypt(string) m = ‘Tittqofe’
Write a program that inputs a student's name in the following form: lastName, firstName middleName. The program will convert the name to the following form: firstName middleName lastName. Your program must read the student's entire name in one variable and must consist of a user-defined function that takes as input a string, consisting of a student's name, and returns the string consisting of the altered name. You can use the string function find to find the index of ,(the comma); the function length to find the length of the string; and the function substr to extract the firstName, middleName, and lastName.
Create a function get-random the parameters -count and the set -maximum and - minimum are mutually exclusive in POWERSHELL as follows: a)Write your own version of get-random that accepts all 3 of -count -min and -max as switches. It should call the standard version to produce results. Your version does not have to handle a list of values. b) The value of count should default to 1 and should have an alias of nItems. c) Write a loop to produce the requested # of items. d) Test your functions with float and integer values. e) Use the group-object cmdlet to prove that your function will generate repeats.
