Password Verifier
Imagine you are developing a software package that requires users to enter their own passwords. Your software requires that user’s passwords meet the following criteria:
- The password should be at least six characters long.
- The password should contain at least one uppercase and at least one lowercase letter.
- The password should have at least one digit.

In C++ Language:
(Check password)
Some websites impose certain rules for passwords. Suppose the password rules are as follows:
- A password must have at least eight characters.
- A password must consist of only letters and digits.
- A password must contain at least two digits.
Write a program that prompts the user to enter a password and displays
valid password if the rules are followed or invalid password otherwise.
Personal BestWrite a program that asks for the name of a pole vaulter and the dates and vaultheights (in meters) of the athlete’s three best vaults. It should then report, in order ofheight (best first), the date on which each vault was made and its height.Input Validation: Only accept values between 2.0 and 5.0 for the heights.
Usernames
An online company needs your help to implement a program that verifies the username chosen by a new user. Their rules is described below:
Username MUST contain at least 6 characters;
Username cannot start with a number;
Username can only contain letters or numbers.
If valid, the username may be resgistered if it doesn't already exist in the system.
You should not use built-in functions to determine the character type such as isnumeric() or islower().
Use the strings given alphabet and numeric to determine if each character is valid.
Use the list registered to help you determine if the username is already registered.
Don't forget to execute the cell below to use these strings
# run this cell to create these variablesalphabet = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'numeric = "0123456789"registered = ["john87", "topmage", "light4ever", "username2"]

Then use the built-in function random first to generate a number between 0 and 6 (including). The expression (random) by itself generates a random integer. You can call it with one parameter to return a value within the range from 0 to the value of the parameter-1. For example, (random 10) will return a value between 0 and 9. Next, use the number generated at the previous step to retrieve the symbol for the day of the week from the list. Use the built-in elt. Extract the symbol-name of the day first, then apply the built-in function capitalize to it. Use the result in the princ function call, and do the same thing for the next day. Make the function return true (t) instead of the last thing it evaluates, to avoid seeing the message printed more than once.arrow_forward

A palindrome is a word, number, phrase, or other sequence of characters which reads the same backward as forward, such as “SIR”,“raceBIKE”, “Never odd or even”, “20/1/20”. The program should prompt the user to typein a phrase that is at least three characters long, and then tell the user whether the phrasewas a palindrome. Note, the decision should be based solely on letters and numericaldigits, and so it should not consider other characters, such as spaces or exclamationmarks, even though these might be entered by the user. when checking palindromes.A. Select your test data with care. Both palindromes and non-palindromes would be included in this. Provide examples that are text, numeric, and mixed; ignore any additional characters and spaces; andB.

Note that employees may work for fractions of an hour, e.g. 1 and a half hours (1.5 hours).

Write a program that gives the pronunciation of a Hawaiian word. For instance, humuhumunukunukuapua’a phonetic guide would be Hoo-moo-hoo-moo-noo-koo-noo-koo-ah-poo-ah'ah The program should start by prompting for and reading in a Hawaiian word (or phrase) from the user. Check if the word is a valid by checking that it only has valid Hawaiian characters. If the word is not valid, warn the user about the offending character and prompt for a Hawaiian word again. Spaces are breaks for words and should be kept intact. The apostrophe is a hard stop andshould be kept in the word. Print the pronunciation of the word (or phrase). Print a dash after every sound as you see in the examples, so you get the syllables separated. Ask the user if they want to do another word. Valid responses are y, Y, n or N. If they want to play more, they can enter another word. If not, then the program ends.
