- Which of following correctly declares and creates a dynamic double type array, aa, of size 20? Question 80 options: A. double* aa; aa = new int[5]; B. double* aa= new double[5]; C. double aa*; aa = new int[20]; D. double* aa= new double[20]; Which statement is true about static typing? A. the binding of a function call and the function definition occurs at compile time B. the binding of a function call and the function definition occurs at run time C. the binding of the type of a variable and the variable name occurs at run time D. the binding of the type of a variable and the variable name occurs at compile timeYour task is to implement a variation of the classic word game Hangman, which involves playersguessing the letters in a word chosen at random with a finite number of guesses. While there arealternate versions such as category Hangman and Wheel of Fortune, which involve playersguessing idioms, places, names and so on, we will be sticking with the traditional version. Requirements:You will implement a function called main that allows users to play an interactive hangman gameagainst the computer. The computer should pick a word, and players should then try to guess lettersin the word until they win or run out of guesses.Here is the overarching behaviour we expect:1. The program should load a list of available words from the text file provided. Note thatthe file you have been given contains words in lowercase.2. The computer should then select a word at random from the list at random.3. The user is given a certain number of guesses at the beginning.4. The game is interactive; the user…Javascript I am stuck on a piece of code and I can quite figure out how to finish one part of this function. This is what I have so far: const usersTestArray = [ {id: "1", name: "Joe Graham", option: "option1"}, {id: "2", name: "Kyle Howell", option: "option2"}, {id:"3", name: "Lucy Bauch", option: "option3"}, {id: "4", name: "Sammie Lebsack", option: "option4"} ] const createSelectOptions = (usersTestArray) => { if(!usersTestArray){ return undefined } return userTestArray.map((x) => x.option) } Most of this is correct, however, in the function above, I need to add a create an option element for each user in the array with document.createElement(). I then need to assign the user.id to option.value and the user.name to option.textContent. then it is supposed to return an array of option elements.
- Suppose, we are given a class called Car that has the following 3 attributes named model (string), year (int) and price (float). The function named find_car() takes three input parameters as follows: an object my_car of Car class, a float my_price, and an int age. This function returns True if my_car's price is at least the given price and my_car is not more than age years old. Otherwise it returns False. Choose the best option to fill the gap on Line# 2. Question options: (my_car.my_price <= price) and (2021 - my_car.age) <= year (my_car.price <= my_price) or (2021 - my_car.year) <= age (my_price == price) and (2021 - age) <= year (my_car.my_price >= price) or (2021 - my_car.age) <= year (my_car.price >= my_price) and (2021 - my_car.year) <= ageIn this task, we’re going to be simulating an email message. Some of the logic hasbeen filled out for you in the email.py file.● Open the file called email.py.● Create a class definition for an Email which has four variables:has_been_read, email_contents, is_spam and from_address.● The constructor should initialise the sender’s email address.● The constructor should also initialise has_been_read and is_spam to false.● Create a function in this class called mark_as_read which should changehas_been_read to true.● Create a function in this class called mark_as_spam which should changeis_spam to true.● Create a list called inbox to store all emails (note that you can have a list ofobjects).● Then create the following methods:○ add_email - which takes in the contents and email address from thereceived email to make a new Email object.○ get_count - returns the number of messages in the store.○ get_email - returns the contents of an email in the list. For this, allowthe user to input an index…Which of the following statements about Python is true? A. Python does not support inheritance. B. Python does not support operator overloading. C.

The endpoint will be /specialOperation This endpoint will take the parameters: length, width, and grade It will asynchronously (with your utility module) get the grade result and rectangle result.

- 2. David is used to doing programming in Python and since the print() function in Python by default prints a newline after printing the string passed to the print() function. But in his current project, he is using PHP programming language and the echo function does not print a newline by default after the end of the string. So, he often misses giving a newline after printing a message. Help David by writing a function myecho() that takes a string as a parameter and also prints a newline after printing the string.What is a stub? Group of answer choices A stub is an inline function with a single line that simply sends a "Hello" message to others, indicating that it has been activated. A stub is a function that has an empty body. It will be developed later. A stub is an inline function with a single line that simply increases the pass in value by one. A stub is a function with a single line that simply prints the name of the function, indicating that it has been activated. A stub is a short function that will generate an error message.Each function (function name plotNegXSquaredPlus25) should accept two integer parameters indicating the minimum and maximum X value to be plotted. The functions should have no return values. Create class-level constants for things we might wish to change later, e.g., a char called PLOT_CHAR that holds an “x” (per samples below), another char called FILL_CHAR that holds an unobtrusive character like ASCII 183, generated with a cast, e.g., (char)183. JAVA PLEASE THOSE ARE NOT PERIODS OR DOTS. USE (System.out.print((Char)183); for (.) Please DON'T USE Loops(while);, if, Arrays, lists, or other data structures, objects, libraries, or methods.
