- 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.arrow_forwardGuess The Number Game: write a program that will ask the user to guess a secret numberrandomly generated by your program between 1-10. Player have 3 trials to guess the number.After each trial, you have to inform the user, either he/she has guessed it correctly or not, andthe remaining trials to guess the number. In each trial your program should generate a newrandom number. If user guess at least twice correctly, then shows the message, “you won by 2-1” and vice versa for losing.When game is over, ask the user to play again: If the user types "yes", the game start again.else stop the game.arrow_forwardTime CalculatorWrite a program that asks the user to enter a number of seconds.-There are 60 seconds in a minute. If the number of seconds entered by the user is greater than or equal to 60, the program should display the number of minutes and leftover seconds in that many seconds.-There are 3,600 seconds in an hour. If the number of seconds entered by the user is greater than or equal to 3,600, the program should display the number of hours, minutes, and leftover seconds in that many seconds.-There are 86,400 seconds in a day. If the number of seconds entered by the user is greater than or equal to 86,400, the program should display the number of days, hours, minutes, and leftover seconds in that many seconds.arrow_forward
- (Parking fee) The short-term, 0-24 hours, parking fee, F, at an international airport is given by the following formula: where int(h + 1) is the integer value of h + 1. For example, int(3.2) = 3, int(4.8) = 4. Write a program that prompts the user to enter the number of hours a car is parked at the airport and outputs the parking fee.arrow_forwardThe great circle distance is the distance betweentwo points on the surface of a sphere. Let (x1, y1) and (x2, y2) be the geographicallatitude and longitude of two points. The great circle distance between the twopoints can be computed using the following formula:d = radius X arccos(sin (x1) X sin(x2) + cos(x1) X cos(x2) X cos(y1 - y2))Write a program that prompts the user to enter the latitude and longitude of twopoints on the earth in degrees and displays its great circle distance. The averageradius of the earth is 6,371.01 km. Note you need to convert the degrees into radiansusing the Math.toRadians method since the Java trigonometric methods useradians. The latitude and longitude degrees in the formula are for north and west.Use negative to indicate south and east degrees. Here is a sample run: Enter point 1 (latitude and longitude) in degrees: 39.55 −116.25 ↵EnterEnter point 2 (latitude and longitude) in degrees: 41.5 87.37 ↵EnterThe distance between the two points is…arrow_forwardNeed help coding in Java Morgan’s Department Store distributes bonuses to its salespeople after the holiday rush. Table 9-6 shows the bonuses, which are based on full weeks worked during the season and the number of positive online customer reviews. Write a program that allows a user to continuously enter values for the number of weeks worked and the number of positive reviews received and displays the appropriate bonus until the user enter a sentinel value: 99.arrow_forward
- (Financial application: calculate future investment value) Write a program**(PYTHON)** that reads in an investment amount, the annual interest rate, and the number of years, and displays the future investment value using the following formula: futureInvestmentValue = investmentAmount * (1 + monthlyInterestRate)^numberOfMonths For example, if you enter the amount 1000, an annual interest rate of 4.25%, and the number of years as 1, the future investment value is 1043.33. Here is a sample run: Enter investment amount: 1000 Enter annual interest rate: 4.25 Enter number of years: 1 Accumulated value is 1043.33arrow_forward(Geometry: distance of two points) Write a program that prompts the user to enter two points (x1, y1) and (x2, y2) and displays their distance between them. The formula for computing the distance is: Square root of ((x2 - x1) squared + (y2 - y1) squared) Note that you can use pow(a, 0.5) to compute square root of a. Sample Run Enter x1 and y1: 1.5 -3.4 Enter x2 and y2: 4 5 The distance between the two points is 8.764131445842194arrow_forwardC++ coding In order to paint a wall that has a number of windows, we want to know its area. Each window has a size of 2 ft by 3 ft. Write a program that reads the width and height of the wall and the number of windows, using the prompts Wall width: Wall height: Number of windows: Then print the area with two digits after the decimal point: Area: ...arrow_forward
- Salary Calculator Create a program that computes the salary based on an employee's hourly wage and hours worked. Note that employees may work for fractions of an hour, e.g. 1 and a half hours (1.5 hours). Use the following formulas: Less than or equal to 40 hours worked hourly wage * hours worked Over 40, but less than or equal to 65 hours worked (hourly wage * 40) + (hours worked - 40) * (hourly wage * 1.5) Over 65 hours worked (hourly wage * 40) + (hourly wage * 1.5) * 25 + (hours worked - 65) * hourly wage * 2 Also make sure that the hourly wage and hours worked are positive. Otherwise, display the error message: "Invalid input". Please see the sample outputs below to guide the design of your program. main.cc file #include <iomanip> #include <iostream> int main() { // TODO: accept user input to store the hourly wage and hours worked. // Then, include the header file at the top of this file so you can // call your function that computes a…arrow_forwardCoin Converter Lab Description Write a program that asks the user to enter an amount of money in the format of dollars and remaining cents. The program should calculate and print the minimum number of coins (quarters, dimes, nickels and pennies) that are equivalent to the given amount.Hint: In order to find the minimum number of coins, first find the maximum number of quarters that fit in the given amount of money, then find the maximum number of dimes that fit in the remaining amount, and so on. File Name coins.py Score There are five tests each worth 2 points For example, an execution should look like this:Please enter the amount of money to convert:# of dollars: 2# of cents: 37The coins are 9 quarters, 1 dimes, 0 nickels and 2 pennies python labsarrow_forwardC# (Guess the Number Game) Write a program that plays “guess the number” as follows: Your program chooses the number to be guessed by selecting an int at random in the range 1–1000. The program then displays the following text in a label: A TextBox should be used to input the guess. As each guess is input, the background color should change to red or blue. Red indicates that the user is getting “warmer,” blue that the user is getting “colder.” A Label should display either “Too High” or “Too Low,” to help the user zero in on the correct answer. When the user guesses the correct answer, display “Correct!” in a message box, change the Form’s background color to green and disable the TextBox. Recall that a TextBox (like other controls) can be disabled by setting the control’s Enabled property to false. Provide a Button that allows the user to play the game again. When the Button is clicked, generate a new random number, change the background to the default color and enable the TextBox.arrow_forward
