Question

Gregor, a software developer, is developing a calendar application. He has to use several if conditional statements to ensure that the calendar displays the exact number of days present in each month of each year. He creates a dayCount array to keep track of the number of days in each month. Gregor wants to ensure February contains 29 days only in the year 2020 as it is a leap year. Which of the following should Gregor use to set the value in the dayCount array?

a) 29
b) 28
c) 30
d) 31

Answer 1

Main Answer:

February in 2020 is a leap year with 29 days; use "29" in dayCount array for accurate calendar representation. a) 29

Therefore, the correct answer is a) 29.

Explanation:

To accurately represent the leap year of 2020 in the dayCount array for his calendar application, Gregor should use the value "29." February typically has 28 days, but during a leap year like 2020, it gains an extra day, totaling 29 days. This ensures that the calendar application accurately reflects the specific number of days in each month, aligning with the leap year cycle.

In a leap year, an extra day is added to the calendar to compensate for the slightly longer time it takes the Earth to complete its orbit around the sun. This adjustment helps maintain synchronization between the calendar year and the astronomical year. For programmers like Gregor, handling leap years is crucial in creating accurate and reliable date and time functionalities.

By setting the value in the dayCount array to "29" for February in the year 2020, Gregor ensures that his calendar application accommodates the leap year properly. This attention to detail is essential for providing users with a precise and dependable tool for managing dates. Using "29" as the value accurately captures the unique nature of February in a leap year.

Therefore, the correct answer is a) 29.
