I have seen some solutions to this problem in Bartleby's library that make no sense to me. I am learning C++, more specifically working with dynamic integers and have become confused with what has been provided previously by others. Using dynamic integers, can I get help with creating a class named 'largeIntegers' so that an object of this class can store an integer of any number of digits. If I could get help with setting up operations to add, subtract, multiply, and compare integers stored in two objects. Also, if someone could explain and help myself create constructors to properly initialize objects and functions to set, retrieve, and print the values of objects. There are three files I am working with: main.cpp, largeIntegers.h, and largeIntegers.cpp largeIntegers.cpp #include <iostream> using namespace std; largeIntegers.h //Specification file largeIntegers.h #ifndef H_largeIntegers #define H_largeIntegers #include <iostream> using namespace std;…
Create a social network, Chirper, that lets the user add new Chirps and like existing Chirps. It's lonely because only one person can add and like messages -- so there's really not much "social" about it. At least you can practice using objects, references, and function overloading in C++! Here's an example of how this program will run You can "chirp" a new message to Chirper, or "like" an existing chirp, or "exit". What do you want to do? chirp What's your message? This is my first chirp! Chirper has 1 chirps: 1. This is my first chirp! (0 likes) You can "chirp" a new message to Chirper, or "like" an existing chirp, or "exit". What do you want to do? like Which index do you want to like? 1 Chirper has 1 chirps: 1. This is my first chirp! (1 likes) You can "chirp" a new message to Chirper, or "like" an existing chirp, or "exit". What do you want to do? chirp What's your message? Second chirp is the best chirp. Chirper has 2 chirps: 1.

Help, I making a elevator simulator, I need help in writing code in the Elevator class and it's polymorphism class. I am not sure what to do next. Any help is appreciated. There are 4 types of passengers in the system:Standard: This is the most common type of passenger and has a request percentage of 70%. Standard passengers have no special requirements.VIP: This type of passenger has a request percentage of 10%. VIP passengers are given priority and are more likely to be picked up by express elevators.Freight: This type of passenger has a request percentage of 15%. Freight passengers have large items that need to be transported and are more likely to be picked up by freight elevators.Glass: This type of passenger has a request percentage of 5%. Glass passengers have fragile items that need to be transported and are more likely to be picked up by glass elevators. There are 4 types of elevators in the system:StandardElevator: This is the most common type of elevator and has a request…
Write a C++ program. Only use string, vector and iterator types from STL for solving these two problems. You can also use a math library. Q2: Design a game that mimics Wordle. Design the code by using functions as much as you can. You do not need to design a graphical interface as shown on the website. This assignment is about designing the underlying logic. Hardcode a set of valid dictionary words in your program. At the end of each try, you can output the text as shown in their example below (i.e., "The letter W is in the word and in the correct spot."): W EARY The letter W is in the word and in the correct spot. ILLS The letter I is in the word but in the wrong spot. V AGUE The letter U is not in the word in any spot.

Instead of using: print(f"You should be spending {hours_inhome} hours on homework outside of class every week") for a beginner in python what is an alternative to using "f" and the { } signs for when you type in print. Also can you explain what the f means and what "{ }" these signs are?
