• 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(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(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
- 4. During each summer, John and Jessica grow vegetables in their backyard and buy seeds and fertilizer from a local nursery. The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly. // Logic errors. #include #include using namespace std; int main() { double costs double area; double bagsize; cout > bagsize; cout > cost; cout > area; cout << endl; cout << "The cost of the fertilizer per pound is: $" << bagsize / cost << endl; cout << "The cost of fertilizing per square foot is: $" << area / cost << endl; return 0; }arrow_forward(Misc. application) a. Write a program that continuously requests a grade to be entered. If the grade is less than 0 or greater than 100, your program should print an appropriate message informing the user that an invalid grade has been entered; else, the grade should be added to a total. When a grade of 999 is entered, the program should exit the repetition loop and compute and display the average of the valid grades entered. b. Run the program written in Exercise 2a and verify the program by using appropriate test data.arrow_forward18. Tom and Jerry opened a new lawn service. They provide three types of services: mowing, fertilizing, and planting trees. The cost of mowing is $35.00 per 5,000 square yards, fertilizing is $30.00 per application, and planting a tree is $50.00. Write an algorithm that prompts the user to enter the area of the lawn, the number of fertilizing applications, and the number of trees to be planted. The algorithm then determines the billing amount. (Assume that the user orders all three services.) (9)arrow_forward
- An online book club awards points to its customers based on the number of books purchased each month. Points are awarded as follows: Books Purchased Points Earned 1 5 2 15 3 30 4 or more 60 Write a program that asks the user to enter the number of books purchased this month and then displays the number of points awarded.arrow_forward3. Fat Gram Calculator Design a program that asks for the number of fat grams and calories in a food item. Validate the input as follows: • Make sure the number of fat grams and calories is not less than 0. According to nutritional formulas, the number of calories cannot exceed fat grams X 9. Make sure that the number of calories entered is not greater than fat grams × 9. Once correct data has been entered, the program should calculate and display the percentage of calories that come from fat. Use the following formula: Percentage of calories from fat = (Fat grams × 9) ÷ Calories Some nutritionists classify a food as "low fat" if less than 30 percent of its calories come from fat. If the results of this formula are less than 0.3, the program should display a message indicating the food is low in fat.arrow_forward**using C# and Visual Studio design a program to satisfy the below problem** Create an application that generates a random number in the range of 1 through 100 and asks the user to guess what the number is. If the user’s guess is higher than the random number, the program should display “Too high, try again.” If the user’s guess is lower than the random number, the program should display “Too low, try again.” If the user guesses the number, the application should congratulate the user and then generate a new random number so the game can start over. Optional Enhancement: Enhance the game so it keeps count of the number of guesses that the user makes. When the user correctly guesses the random number, the program should display the number of guesses.arrow_forward
- mystery_value = 5 #You may modify the lines of code above, but don't move them!#When you Submit your code, we'll change these lines to#assign different values to the variables. #Write a program that divides mystery_value by mystery_value#and prints the result. If that operation results in an#error, divide mystery_value by (mystery_value + 5) and then#print the result. If that still fails, multiply mystery_value#by 5 and print the result. You may assume one of those three#things will work.##You may not use any conditionals.# #Add your code here!arrow_forwardA car’s miles-per-gallon (MPG) can be calculated with the following formula:MPG 5 Miles driven Gallons of gas usedWrite a program that asks the user for the number of miles driven and the gallons of gas used. It should calculate the car’s MPG and display the result.arrow_forwardPart 4 Add this comment: # Ass 1: Part 4 Write a program that generates a random number in the range of 1 through 100, and asks the user to guess what the number is. If the user's guess is higher than the random number, the program should display "Too high, try again." If the user's guess is lower than the random number, the program should display "Too low, try again." If the user guesses the number, the program should congratulate the user by displaying "You won, congratulations.". Samplel: Please enter your guess value: 10 Too low, try again. Please enter your guess value: 15 Too low, try again. Please enter your guess value: 30 Too low, try again. Please enter your guess value: 50 Too low, try again. Please enter your guess value: 60 Too high, try again. Please enter your guess value: 55 Too high, try again. Please enter your guess value: 53 You won, congratulations. Sample2:arrow_forward
