Summary During winter when it is very cold, typically, everyone would like to know the windchill factor, especially, before going out. Meteorologists use the following formula to compute the windchill factor, W: W = 35.74 + 0.6215 × T - 35.75 × V0.16 + 0.4275 × T × V0.16 where V is the wind speed in miles per hour and T is the temperature in degrees Fahrenheit. Instructions Write a program that prompts the user to input the wind speed in miles per hour, and the temperature in degrees Fahrenheit. The program then outputs the current temperature and the windchill factor. Your program must contain at least two functions: one to get the user input and the other to determine the windchill factor.
Ron bought several acres of farm to grow and sell vegetables. Suppose that Ron wants to grow a maximum of two types of vegetables. Write a program that prompts Ron or the user to do the following: Enter the total farm area in acres. The number of vegetables (one or two) that the user wants to grow. If the user wants to grow trwo types of vegetables, then specify the portion,as a percentage, of the farm land used for each type of vegetable. Enter the seed cost, plantation cose, fertilizing cost, labor cost, for each acre. Enter vegetable selling price per acre. Output the total revenue. Output the profit/loss.
How do I do this? Write pseudocode to calculate the weekly pay for employees. The user will prompted to enter the number of hours worked and their job code. Hours in excess of 40 are paid at 1.5 times the hourly pay. Job code hourly rates are: P - $10, Q - $12.50, R - $15.00, and S - $20.00. Use both a case and a selection structure.
(Science: calculating energy) Write a program that calculates the energy needed to heat water from an initial temperature to a final temperature. Your program should prompt the user to enter the amount of water in kilograms and the initial and final temperatures of the water. The formula to compute the energy is Q = M * (finalTemperature – initialTemperature) * 4184 where M is the weight of water in kilograms, temperatures are in degrees Celsius, and energy Q is measured in joules.

A software company sells a package that retails for $99. Quantity discounts are given according to the following table: Quantity Discount 10 – 19 10% 20 – 49 20% 50 – 99 30% 100 or more 40% Write a program that asks the user to enter the number of packages purchased. The program should then display the full retail price before any discount, the amount of the discount (if any), and the total amount of the purchase after any discount. Do not allow numbers less than 0.
Create a change-counting game that gets the user to enter the number of coins required to make exactly one dollar. The program should let the user enter the num- ber of pennies, nickels, dimes, and quarters. If the total value of the coins entered is equal to one dollar, the program should congratulate the user for winning the game. Otherwise, the program should display a message indicating whether the amount entered was more than or less than one dollar.
(Geometry: great circle distance) The great circle distance is the distance between two points on the surface of a sphere. Let (x1, y1) and (x2, y2) be the geographi- cal latitude and longitude of two points. The great circle distance between the two points can be computed using the following formula: d = radius * arccos(sin(x1) * sin(x2) + cos(x1) * cos(x2) * cos(y1 - y2)) Write a program that prompts the user to enter the latitude and longitude of two points on the earth in degrees and displays its great circle distance. The average earth radius is 6,378.1 km. The latitude and longitude degrees in the formula are for north and west. Use negative to indicate south and east degrees.
View the code and add the following: This is also inside the code to show you where it must be added. % use an if/else statement to check to see if the ball is moving % down (negative). If it is, then drag has an opposite sign % as gravity in the acceleration formula. Otherwise gravity % and drag have the same sign. Calculated the acceleration % in the y direction inside the if/else statement. % Now calculate the acceleration in the x . % ******************************************************* % ***************************************************** % calculate the new velocity at the end of the time step % this will have X and Y components, so you need a variable % for each.

Celsius to Fahrenheit: Write a program that converts Celsius temperatures to Fahrenheit temperatures. The formula or algebraic equation is F = ?? / ?? * C + 32, where F is the Fahrenheit temperature, and C is the Celsius temperature. Input: temperature in Celsius Output: as shown below Topic: arithmetic expressions, cin, cout, integer division Note: Please notice that the input is an integer but the output contains decimal numbers with one decimal place.
A retail store grants its customers a maximum amount of credit. Each customer’s available credit is his or her maximum amount of credit minus the amount of credit used. Write a program that asks for a customer’s maximum amount of credit and then asks for the amount of credit used. The program should then properly display the customer’s available credit. Be sure that you check that the user is entering positive values and that the display is formatted correctly.
