we have to find out the leap years between 1990 and 2006. First define the two years under a class "leapyears". Let i = 2006 and n=1990. Now with the help of for loop method initialize the year as n=1990 and n<=i. Also apply the increment statement in the loop as we have to check one by one. As we know a leap year is divisible by 4, define an integer l=n%4. So if 'n' is divisible by 4 or l=0, then the particular year can be a leap year. For checking this, apply the if statement and if this satisfies then, the year ... Read Full Story
