February Days
The month of February normally has 28 days. But if it is a leap year, February has 29 days. Write a
1. Determine whether the year is divisible by 100. If it is, then it is a leap year if and if only it is also divisible by 400. For example, 2000 is a leap year but 2100 is not.
2. If the year is not divisible by 100, then it is a leap year if and if only it is divisible by 4. For example, 2008 is a leap year but 2009 is not.
Here is a sample run of the program:
Enter a year: 2020[Enter]
In 2020 February has 29 days.

- (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.arrow_forwardCelsius 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.arrow_forwardC-Program for blood pressure. The program (screenshot below) compares the systolic & diastolic measurements to output whether the blood is (low, ideal, pre-high, or high) The code I wrote is able to successfully determine the blood pressure type as long as it lies within the same range. However, if it goes outside that range it prints an error. FOR EXAMPLE**** PLEASE READ*** If the user inputs their systolic variable as 100 and their systolic as 90, it will print an error. If the systolic & diastolic measurements are vastly different the program prints an error, if you could help resolve this issue it would be greatly appreciated.arrow_forward
- Area Calculator: Prompt the user to enter two choices 1 or 2. If user enters 1 then ask him for length of side of square and if user enters 2 then prompt for length and breadth of rectangle. In both case the output should be the area of square (case 1) or rectangle (case2). In C++arrow_forwardThe two roots of a quadratic equationax2 + bx + c = 0 can be obtained using the following formula:b2 - 4ac is called the discriminant of the quadratic equation. If it is positive, theequation has two real roots. If it is zero, the equation has one root. If it is negative,the equation has no real roots.Write a program that prompts the user to enter values for a, b, and c and displaysthe result based on the discriminant. If the discriminant is positive, display tworoots. If the discriminant is 0, display one root. Otherwise, display “The equationhas no real roots.”Note you can use Math.pow(x, 0.5) to compute √x. Here are some sampleruns: Enter a, b, c: 1.0 3 1 ↵EnterThe equation has two roots -0.381966 and -2.61803arrow_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_forward
- 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_forwardIPO Chart/ Flow Chart/Pseudocode Write a guessing game where the user has to guess a secret number. After every guess, the program tells the user whether their number was too large or too small. In the end, the number of tries needed should be printed. It counts only as one try if they input the same number multiple times consecutively. Based on this, create: a) IPO chart(s) b) Flowchart(s)c) Pseudocode for the following problem set.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_forward
- Time 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_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
