C++ program

Dairy Farm decided to ship milk in containers in the form of cubes rather than cylinders.

Write a program that prompts the user to input:

1. The radius of the base of a cylindrical container
2. The height of the cylindrical container

The program then outputs:

1. The side of the cube with the same volume as the cylindrical container with a precision of 2 decimal places.

You may assume that the value of π = 3.141593.

This is a Python project and I´m wondering if anyone has a simple solution for this?

Write a program, move.py, which asks the user for the position of a virtual character on the x-axis in a coordinate system and then allows the user to move the virtual character to the right or left, indicated by the characters 'r' or 'l'. The user should be able to move the virtual character as often as he/she wishes, but if the input is neither 'r' nor 'l' the program quits. Instructions for the user are written out at the beginning, but the position of the virtual character (denoted by 'o') is shown in each iteration.

The valid range on the x-axis, which the virtual character can traverse, is from 1 to 10 and you can assume that at the beginning the user inputs a number in this range. If the virtual character is positioned at either end of the range it will not move when the user tries to move it out of the range.

In your solution, you should only use methods/material discussed in the first five chapters in the textbook. This means, for example, that you are not allowed to use lists.

Make sure that your code is very readable (see, for example, this thread).

Note the following:

• The numbers 1 and 10, which signify the range, should be implemented as constants. In Python, a constant is a variable whose value will not change in the program. It is a good rule to use capital letters for naming constants.
• You must use functions in your implementation. It is fine that your main program contains the loop, but the body of the loop should, in most part, be a series of function calls.
• Example input/output is below. Your output should be exactly the same.

Example input/output:

Input a position between 1 and 10: 7
xxxxxxoxxx
l - for moving left
r - for moving right
Any other letter for quitting
Input your choice: r
xxxxxxxoxx
Input your choice: r
xxxxxxxxox
Input your choice: r
xxxxxxxxxo
Input your choice: r
xxxxxxxxxo
Input your choice: l
xxxxxxxxox
Input your choice: l
xxxxxxxoxx
Input your choice: l
xxxxxxoxxx
Input your choice: l
xxxxxoxxxx
Input your choice: q
xxxxxoxxxx

Program 1:

For this program, imagine we want to track an object and detect if it goes off the left or right side of the screen (that is, it’s X position is less than 0 and greater than the width of the screen, say, 100). Write a program that asks the user for the starting X and Y position of the object as well as the starting X and Y velocity, then prints out its position each frame until the object moves off of the screen. Design (pseudocode) and implement (source code) for this program.

Sample run 1:

Enter the starting X position: 50

Enter the starting Y position: 50

Enter the starting X velocity: 4.7

Enter the starting Y velocity: 2

X:50 Y:50

X:54.7 Y:52

Program 2:

Buh-RING IT! For this assignment, you’re going to simulate a text-based Role-Playing Game (RPG). Design (pseudocode) and implement (source) for a program that reads in 1) the hero’s Hit Points (HP – or health), 2) the maximum damage the hero does per attack, 3) the monster’s HP and 4) the maximum monster’s damage per attack. When the player attacks, it will pick a random number between 0 and up to the maximum damage the player does, and then subtract that from the monster. The same thing happens when the monster attacks the hero, but damage is to the hero. The program should display rounds and the HP of the hero and monster each round. If the hero or monster dies, it should print that this happened and should NOT continue (i.e. no extra text). To learn how to create random numbers, see the appendix.

Sample run 1:

Enter the hero's starting hit points: 50

Enter the damage the hero’s weapon does per strike: 20

Enter the monster's starting hit points: 40

Enter the monster's damage per strike: 15

====== ROUND 1 ======

Hero attacks for: 10

Monster has 30 HP left

Monster attacks you for: 1

You have 49 HP left

====== ROUND 2 ======

Hero attacks for: 18

Monster has 12 HP left

Monster attacks you for: 7

You have 42 HP left

====== ROUND 3 ======

Hero attacks for: 0

Monster has 12 HP left

Monster attacks you for: 14

You have 28 HP left

====== ROUND 4 ======

Hero attacks for: 18

Monster has -6 HP left

The monster dies and you earn 5 XP

Battle ends...

Did you know that, over the last century, the stock market has returned an average of 10%? You may not care, but you’d better pay attention to this one. If you were to give a newborn baby $5000, put that money in the stock market and NOT add any additional money per year, that money would grow to over $2.9 million by the time that baby is ready for retirement (67 years)! Don’t believe us? Check out the compound interest calculator from MoneyChimp and plug in the numbers! To keep things simple, we’ll calculate interest in a simple way. You take the original amount (called the principle) and add back in a percentage rate of growth (called the interest rate) at the end of the year. For example, if we had $1,000 as our principle and had a 10% rate of growth, the next year we would have $1,100. The year after that, we would have $1,210 (or $1,100 plus 10% of $1,100). However, we usually add in additional money each year which, for simplicity, is included before calculating the interest. Your task is to design (pseudocode) and implement (source) for a program that 1) reads in the principle, additional annual money, years to grow, and interest rate from the user, and 2) print out how much money they have each year. Task 3: think about when you earn the most money! Lesson learned: whether it’s your code or your money, save early and save often…

Sample run 1:

Enter the principle: 2000

Enter the annual addition: 300

Enter the number of years to grow: 10

Enter the interest rate as a percentage: 10

Year 0: $2000

Year 1: $2530

Year 2: $3113

Year 3: $3754.3

Year 4: $4459.73

Year 5: $5235.7

Year 6: $6089.27

Year 7: $7028.2

Year 8: $8061.02

Year 9: $9197.12

Year 10: $10446.8

Sports Stuff, Inc. (SSI) is a manufacturing firm that produces sporting goods. They have started operating a factory in the U.S. and have opened a company owned store adjacent to the factory.

A loan company wants to design a database to track student loans. Each student attending school is eligible for a loan. A student may have more than one loan. A student may be registered, possibly at different times, in more than one school. Each loan should belong to only one bank. Each bank can approve as many loans as it desires. For each loan, the loan company will track: the student’s SSN, name, address, amount of loan, date of the loan, interest rate ( which may be different for each loan as determined by the bank), duration of the loan, monthly payment, remaining balance, school ID, school name and address, number of years the student has been at the school, bank name, bank branch, and bank ID. Draw an ER diagram. State any assumptions you make in the diagram. Note: You must use one of the automated database design tools such as: ER STUDIO ER Assistant Vision Enterprise or draw.io website.

Now suppose Thermata officers want to ascertain employee satisfaction with the company. They randomly sample nine employees and ask them to complete a satisfaction survey under the supervision of an independent testing organisation. As part of this survey, employees are asked to respond to questions on a 5-point scale where 1 is low satisfaction and 5 is high satisfaction. The questions and the results of the survey are shown in the next column. Analyse the data by finding a confidence interval (with =0.05) to estimate the population response to each of these questions. Provide your interpretation and discussions of the results.

A 3.61 kg particle has the xy coordinates (-1.06 m, 0.516 m), and a 3.39 kg particle has the xy coordinates (0.820 m, -0.0640 m). Both lie on a horizontal plane. At what (a) x and (b) y coordinates must you place a 2.60 kg particle such that the center of mass of the three-particle system has the coordinates (-0.672 m, -0.106 m)?
