PROGRAMMING LANGUAGE: C++ALSO PASTE SCREENSHOTS OF OUTPUTS
You are required to create a simulation of an elevator system. There are 7 floors in a building. A user may enter the elevator and press the button of the destined floor. The simulation should display appropriate messages while moving towards the destined floor.
Hands-On Activity 4-4
BuzzButtons is a novelty item company manufacturing personalized
lapel buttons that buzz randomly. The buttons are marketed as a
conversation starter, and the company's slogan is "It starts the buzz!"
The owner is promoting his buttons by offering them at 99 cents
each. He wants you to design a program asking the user for his or her
name for the button, an e-mail address, and the number of buttons to
order. The program should then add a 6% sales tax and a flat shipping
rate of $2.00. The program displays the information the user enters
as well as the button price total, sales tax amount, shipping amount,
and order total. The company contacts the user by e-mail later for
shipping address information.
Using pseudocode, design an algorithm that asks the user for the
number of fixed-price items to order, adds sales tax and flat-rate ship-
ping, and displays the result. Save your pseudocode file in Notepad as
buzzButtons.txt.
Task using C language
Two spacecrafts are traveling at different speeds from Earth to Mars. While spacecraft A doubles its speed every day, spacecraft B triples its speed in the same period. Given their initial speeds, your task is to determine how many days spacecraft B will take to travel faster than spacecraft A.
If the initial speed of spacecraft A is 7, it will be 14 after 1 day, 28 after 2 days, and so on.
If the initial speed of spacecraft B is 4, it will be 12 after 1 day, 36 after 2 days, and so on.
If the initial speed of spacecrafts A and B are 7 and 4, respectively, B will be faster than A after 2 days, as the speed of A will be 28 and the speed of B will be 36.
Requirements
Follow the format of the examples below.
You will be given several test cases in a single run, and you must provide an answer for all of them.

- Computer Science Godot Programming Programming Problem 1. Rock, Paper, Scissors This is your traditional rock-paper-scissors game, where two players select one of the three options and a result is produced based on their selection. For reference: Rock beats scissors Paper beats rock Scissors beats paper For this problem, you are to assume that two human players will play against each other and will input their choices accordingly. The input for each player will be in the form of buttons. Once a player clicks on a button, the rest of their buttons are locked in place (i.e. disabled). Once the other player selects their pick, the program outputs who won or if there was a draw. This isn’t exactly the most realistic way to code the game as it would be better if both players made their choice at the same time, but we’ll just have to chalk this up as a limitation for our exam. Aside from the game itself, the program should track the score of each player. Basically, if one wins, that…arrow_forwardPROGRAMMING LANGUAGE: C++ TASK 1.

Write a program that takes +,-,*, and / operators and performs the required operation. the program will continue to execute until ESC key is pressed. Also, the usage of post-test loop and switch statement is mandatory.arrow_forwardInterest Rates Savings accounts state an interest rate and a compounding period. If theamount deposited is P, the stated interest rate is r, and interest is compounded m timesper year, then the balance in the account after one year is P⋅(1+rm)m. For instance, if$1000 is deposited at 3% interest compounded quarterly (that is, 4 times per year), thenthe balance after one year is1000⋅(1+.034)4=1000⋅1.00754=$1,030.34.Interest rates with different compounding periods cannot be compared directly.The concept of APY (annual percentage yield) must be used to make the comparison. TheAPY for a stated interest rate r compounded m times per year is defined byAPY=(1+rm)m−1.(The APY is the simple interest rate that yields the same amount of interest after oneyear as the compounded annual rate of interest.) Write a program to compare interestrates offered by two different banks and determine the most favorable interest rate. SeeFig. 4.24.arrow_forward

For example, starting with n = 5, we get the sequence 5, 16, 8, 4, 2, 1. If n is 6, we get the sequence 6, 3, 10, 5, 16, 8, 4, 2, 1. If n is 7, we get 7, 22, 11, 34, 17, 52, 26, 13, 40, 20, 10, 5, 16, 8, 4, 2, 1. If n is 8, we get the sequence 8, 4, 2, 1. As far as anyone can tell, this process will eventually reach 1 for any starting value, although mathematicians have been unable to formally prove this property as of yet. a.

Those numbers for which this process ends in 1 are happy numbers, while those that do not end in 1 are unhappy numbers. Input: Your program should read lines of text from standard input.

- python solution please Task 1Description let's consider a case when you need a lot of coffee. Maybe you're hosting a party with a lot of guests! In these circumstances, it's better to make preparations in advance.So, we will ask a user to enter the desired amount of coffee, in cups. Given this, you can adjust the program by calculating how much water, coffee, and milk are necessary to make the specified amount of coffee.Of course, all this coffee is not needed right now, so at this stage, the coffee machine doesn't actually make any coffee yet. ObjectivesLet's break the task into several steps:First, read the numbers of coffee drinks from the input.Figure out how much of each ingredient the machine will need. Note that one cup of coffee made on this coffee machine contains 200 ml of water, 50 ml of milk, and 15 g of coffee beans.Output the required ingredient amounts back to the user.
