Question

A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The requirements for a given year to be a leap year are: 1) The year must be divisible by 4 2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400 Some example leap years are 1600, 1712, and 2016. Write a program that takes in a year and determines whether that year is a leap year.

Answer 1

Answer:

i_year=int(input(""))

#check leap year

if((i_year % 4 == 0 and i_year % 100 != 0) or (i_year % 400 == 0)):

  print("{} is a leap year.".format(i_year))

else:

  print("{} is not a leap year.".format(i_year))

Explanation:

Answer 2

Answer:

import java.util.Scanner;

public class LabProgram {

  public static void main(String[] args) {

      Scanner scnr = new Scanner(System.in);

      int inputYear;

      boolean isLeapYear;

      isLeapYear = false;

      inputYear = scnr.nextInt();

      // If a year is divisible by 400,  then it is a leap year

      if (inputYear % 400 == 0)

          isLeapYear = true;

      // If a year is divisible by 100,  then it is not a leap year

      if (inputYear % 100 == 0)

          isLeapYear = false;

      // If a year is divisible by 4,  then it is a leap year

      if (inputYear % 4 == 0)

          isLeapYear = true;

      if(isLeapYear)

          System.out.println(inputYear + " is a leap year.");

      else

          System.out.println(inputYear + " is not a leap year.");

  }

}

Explanation:

• Take the year as an input from user and store it to inputYear variable.
• If the year is a century year, check if the year is divisible by 400 ( the year must be evenly divisible by 400 ),  then set the boolean isLeapYear to true. If a year is divisible by 100,  then set the boolean isLeapYear to false. If a year is divisible by 4,  then set the boolean isLeapYear to true.
• Check if isLeapYear is true, then print that it is a leap year. Otherwise, print that it is not a leap year.

Output:

1712

1712 is a leap year.
