Program to check a year is leap year or not.

Image
Problem DescriptionIf a year is divisible by 4, then it is called leap year.But all the centuries are divisible by 4, so to check a century is a leap year or not, we check divisibility by 400 of a year.If a century is divisible by 400 then the century is called leap year otherwise not. Basic Logic Snippets (In C)if(year % 100 == 0) { if (year % 400 == 0) { printf("%d is a leap year",year); } else { printf("%d is not a leap year",year); } }else { if(year % 4 == 0) { printf("%d is a leap year",year); } else { printf("%d is not a leap year",year); } } OutputTest-1 Enter any year: 1996
1996 is a leap year Test-2 Enter any year: 1600
1600 is a leap year Test-3 Enter any year: 1800
1800 is not a leap year Improved your logicNote: Generate wrong output in some cases, but helpful to understand upcoming logicif(year % 100 == 0 && year % 400 ==0 || year % 4 == 0) { printf("%d is a leap year",year); } else { printf(&qu…
