Structured English

Structured English uses a simple English language to make structured programming easier for non-professionals. The program is divided into various parts that are known as logical statements. These statements are written in a simple English language.

Question

Give me right answer please.

A lazy list (aka stream) is like a list except
that it is constructed using the lazy version
of cons: scala> val s1 = 1 #:: 2 #:: 3 #::
LazyList.Empty s1:
scala.collection.immutable.LazyList[Int]
LazyList(1, ?) scala> s1.head res0: Int = 1
scala> s1.tail.head res1: Int = 2
Create the following lazy lists:
An infinitely long stream of 1's
The stream of all non-negative integers
The stream of all non-negative even
integers
The stream of all squares of integers

A for construct is a loop that iteratively processes a given list. So long as there are things to process, it will continue to operate. Is this a true or false statement?

A loop that iteratively processes a given list is called a for construct. So long as there are things to process, it will keep running. To what extent is this statement accurate or false?
When traversing a single- or double-linked list, you should be careful not to fall off the end of the list or you'll get a type your answer.
Write a C++ program to create a queue. The size of the queue will be dependent on the user. Insert the numbers in the queue till the queue reaches the size. Create a menu and perform the following function on that queue. Enqueue: Add an element to the end of the queue. Dequeue: Remove an element from the front of the queue. IsEmpty: Check if the queue is empty. IsFull: Check if the queue is full. Peek: Get the value of the front of the queue without removing it.
The function swap_list_ends in python takes one parameter, L, which is a list. The function then swaps the first and last items in L and returns the object None. Notice that since L is mutable, the changes the function makes to L are visible back in the calling program. SPECIAL CASE: If the list 'L' is empty, then the function does nothing to L and returns None. For example: Test Result L = [1, 3, 9, 2] if not(swap_list_ends(L) is None): print("Error: function should return None") print(L) [2, 3, 9, 1] L = ['super', 'awesome', 'excellent'] if not(swap_list_ends(L) is None): print("Error: function should return None") print(L) ['excellent', 'awesome', 'super'] L = [True, False] if not(swap_list_ends(L) is None): print("Error: function should return None") print(L) [False, True]
Write a python hangman program Modify your program so that the following functionality is added:1.

A for construct is a type of loop that works with the things in a list. Because of this, it will keep running as long as there are items in the system to be handled. Does this statement make a mistake or is it correct?

Help make a C++ program that:1. Queries the user for the name of a file of text.2. Opens the file, and maintains two lists: one list for words beginning with the letter"D" or "d", and a second list for words beginning with any other letter. Each listmust maintain words in alphabetical order.3. Each node in the list must contain the word and the number of times that the word appears.4. Display (a screen at a time) each of the lists showing the alphabetized list of words and thenumber of times that each appears. Please have the main function as the first function in the program. Please make the least amount of functions as possible. Like for the file input have the file error thing in the same function. And please add comments throughout the code.
