• There are 86400 seconds in a day. If the number of seconds entered by the user is greater than or equal to 86400, the program should display the number of days in that many seconds.
• There are 3600 seconds in an hour. If the number of seconds entered by the user is less than 86400 but is greater than or equal to 3600, the program should display the number of hours in that many seconds.
• There are 60 seconds in a minute. If the number of seconds entered by the user is less than 3600 but is greater than or equal to 60, the program should display the number of minutes in that many seconds.

- 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_forward(Conversion) Write an assignment statement to convert temperature in degrees Fahrenheit to degrees Celsius. The formula for this conversion is Celsius=5/9(Fahrenheit32).arrow_forward(Mathematical functions) Write a program that calculates and displays values for y when y=xz/(xz) Your program should calculate y for values of x ranging between 1 and 5 and values of z ranging between 2 and 6. The x variable should control the outer loop and be incremented in steps of 1, and z should be incremented in steps of 1. Your program should also display the message Function Undefined when the x and z values are equal.arrow_forward
- Guess 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_forwardPersonal BestWrite a program that asks for the name of a pole vaulter and the dates and vaultheights (in meters) of the athlete’s three best vaults. It should then report, in order ofheight (best first), the date on which each vault was made and its height.Input Validation: Only accept values between 2.0 and 5.0 for the heights.arrow_forward(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.arrow_forward
- circles) Write a program that prompts the user to enter the center coordinates and radii of two circles and determines whether the second circle is inside the first or overlaps with the first, as shown in Figure 4.11. (Hint: circle2 is inside circle1 if the distance between the two centers <= | r1 - r2| and circle2 overlaps circle1 if the distance between the two centers <= r1 + r2.arrow_forwardSalary 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_forwardWidgets and Gizmos An online retailer sells two products: widgets and gizmos. Each widget weighs 75 grams. Each gizmo weighs 112 grams. Write a program that reads the number of widgets and the number of gizmos in an order from the user. Then your program should compute and display the total weight of the order.arrow_forward
- Q1: (Palindrome number) Write a program that prompts the user to enter a three-digit integer and determines whether it is a palindrome number. A number is palindrome if it reads the same from right to left and from left to right. Here is a sample run of this program: Enter a three-digit integer: 121 121 is a palindrome Enter a three-digit integer: 123 123 not a palindromearrow_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_forwardNice Number Programming: Nice program ask user to enter three integers from keyboard (java console), the three integers represent left bound, right bound and arbitrary digit 'm', where left bound is less than right bound. Program should print all nice numbers in the given range that doesn't contain digit 'm'. The number is nice if its every digit is larger than the sum of digits which are on the right side of that digit. For example 741 is a nice number since 4> 1, and 7> 4+1. with digit m=2. Write a complete program in Java that Call only One method (niceNumbers method) that will print all nice numbers excluding a given digit 'm' that also entered by user?arrow_forward
