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 '@'.) (Sample output as shown in the following figure is for demonstration purposes only.)

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.

Complete the rotate_text() function that takes 2 parameters, a string data and an integer n. If n is positive, then the function will shift all the characters in data forward by n positions, with characters at the end of the string being moved to the start of the string. If n is 0 then the text remains the same. For example: rotate_text('abcde', rotate_text('abcde', rotate_text('abcde', 1) would return the string 'eabcd' 3) would return the string 'cdeab' 5) would return the string 'abcde' rotate_text('abcde', 6) would return the string 'eabcd' ... and so on. If n is negative, then the function will shift the characters in data backward by n positions, with characters at the start of the string being moved to the end of the string. For example: rotate text('abcde', -1) would return the string 'bcdea'

Complete the check_strings_same_start(word1, word2) function which is passed two string parameters. The function returns True if the two parameter strings start with the same character and only one (not both) of the parameter strings has an even number of characters (including any space characters), otherwise the function returns False. For example: Test Result result = check_strings_same_start("blue", "bag") True print(result) print(check_strings_same_start("babyproofing", "baby")) False print(check_strings_same_start("check", "fact")) False
Create a function that accepts a string (of a person's first and last name) and returns a string with the first and last name swapped. Examples NameShuffle("Donald Trump") - "Trump Donald" NameShuffle ("Rosie O'Donnell") - "O'Donnell Rosie" NameShuffle ("Seymour Butts") - "Butts Seymour" • There will be exactly one space between the first and last name. In c#
The function accumulate_acronym has no parameters; it reads strings from standard input and accumulates the corresponding acronym. The end of the input is signaled when the user enters the string "STOP". For example, if the user enters "United Guinea Pig Supporters of America STOP", then the function returns the acronym string, "UGPSoA". The function does not print anything to standard output.
7. Write a Boolean function called contains_whitespace() that accepts a string as a parameter and returns True is the string contains one or more whitespaces (“ ", “/t", “/n") characters, or False otherwise. Write a main() function to demonstrate how it works.
Instructions Write a program that uses the function is Palindrome given in Example 6-6 (Palindrome). Test your program on the following strings: madam, abba, 22, 67876, 444244, trymeuemyrt Modify the function isPalindrome of Example 6-6 so that when determining whether a string is a palindrome, cases are ignored, that is, uppercase and lowercase letters are considered the same. The isPalindrome function from Example 6-6 has been included below for your convenience. bool isPalindrome (string str) { int length = str.length(); for (int i = 0; i < length / 2; i++) { if (str[i] != str[length - 1 - i]) { return false; } // if } // for loop return true; }// isPalindrome Your program should print a message indicating if a string is a palindrome: madam is a palindrome
Task 7 Write a function called show palindrome that takes a number as an argument and then returns a palindrome string. Finally, prints the returned value in the function call. Example1: Function Call: show_palindrome(5) Output: 123454321
PHP Write a matchSSN function Write a function matchSSN($str) that takes a string representing a social security number as a parameter. The function should return true if the SSN is valid, and false if it is not. An SSN consists of 9 digits that are sometimes, but not always, separated by dashes between the 3rd and 4th digits and between the 5th and 6th digits (e.g. 123-45-6789). Use regular expressions in your solution (e.g. preg_match).
in c++: Write a program that prompts the user to input a string. The program then uses the function substr to remove all the vowels from the string. For example, if str = "There", then after removing all the vowels, str = "Thr". After removing all the vowels, output the string. Your program must contain a function to remove all the vowels and a function to determine whether a character is a vowel.
Create a function that takes a string and returns a string with its letters in alphabetical order. Examples alphabet_soup("hello") - "ehllo" alphabet_soup("edabit") - "abdeit" alphabet_soup("hacker") - "acehkr" alphabet_soup ("geek") - "eegk" alphabet_soup("javascript") "aacijprstv"
