Task description:
Use regular expression to implement a function which accepts a passed string and check if it is a
valid email address. A program accepts user's input and calls the email validation function. If the
email is valid, print out the email, username and host. (Rule: word characters (a-zA-Z0-9_ or "\w"),
dot, and hyphen are considered as valid characters in an email address, besides of one & only one
"@'.)

C++
// Write a function that takes 1 argument, a string. // It returns true if the string is a palindrome (the same forwards and backwards). // It returns false if the string is not a palindrome. const isPalindrome = (string) => { // your code here... // Examples isPalindrome("cat") // returns false //isPalindrome("level") // returns true }
use c code to Develop a function that gets two same length strings as parameters and reports the number of characters that they have different. For example, if the two strings are Str1: “Hello world! Happy Friday”Str2: “Hello Johny! happy friday” The function should return: Your strings are different in 7 places However, if the strings are exactly equal, it should just say Your strings are the same If the strings are not of the same length, the code should just say: The two strings are not of the same length! Hint: 1.compare the two strings character by character and report the differences 2.answer must have and show the output
Python question please include all steps and screenshot of code. Also please provide a docstring, and comments throughout the code, and test the given examples below. Thanks. Develop function fingerprint() that takes text (as a string) as input and creates andreturns the text “fingerprint” obtained as follows: replace each word in the text by itslength (i.e., the number of letters) and concatenate these numbers.>>> fingerprint('This is a secret message')'42167'>>> fingerprint('This message has a different fingerprint')'4731911'>>> fingerprint('Very Short')'45'
4. Complete the function show_upper. This function takes one parameter - a string (s). It should return a string made up of all the upper-case characters in s. For example, if s is “aBdDEfgHijK” then show_upper should return “BDEHK”. It should return the upper-case string - not print it. Do not change anything outside show_upper.
