In your preferred language, write a program that works out whether a given year is a leap year. A normal year has 365 days, and leap years have 366, with an extra day in February.
This is how to work out whether a particular year is a leap year:
A year is a leap year if it is evenly divisible by 4 ;
except if that year is also evenly divisible by 100;
unless that year is also evenly divisible by 400.
For more context,
Is the year 2400 a leap year?:
2400 ÷ 4 = 600 (Leap)
2400 ÷ 100 = 24 (Not Leap)
2400 ÷ 400 = 6 (Leap!)
So the year 2400 is a leap year.
But the year 2100 is not a leap year because:
2100 ÷ 4 = 525 (Leap)
2100 ÷ 100 = 21 (Not Leap)
2100 ÷ 400 = 5.25 (Not Leap)
