**Definition of leap year:**

Rule 1: A year is called leap year if it is divisible by 400.

For example: 1600, 2000 etc leap year while 1500, 1700 are not leap year.

Rule 2: If year is not divisible by 400 as
well as 100 but it is divisible by 4 then that year are also leap year.

For example:
2004, 2008, 1012 are leap year.

**Leap year logic or Algorithm of leap year or Condition for leap year:**

IF year MODULER 400 IS 0

THEN
leap_year

ELSE IF year MODULER 100 IS 0

THEN
not_leap_year

ELSE IF year MODULER 4 IS 0

THEN
leap_year

ELSE

not_leap_year

Code 1:

1.

**C program to determine leap year**
2.

**C program to find leap year or not**
3.

**Leap year calculation in c**
#include<stdio.h>

int main(){

int year;

printf("Enter any year: ");

scanf("%d",&year);

if(((year%4==0)&&(year%100!=0))||(year%400==0))

printf("%d is a leap year",year);

else

printf("%d is not a leap
year",year);

return 0;

}

Sample output:

Enter any year: 2010

2010 is not a leap year

Code 2:

1.

**Write a program to find leap year in c**
2.

**How to find leap year in c code**
#include<stdio.h>

int main(){

int year;

int min_year,max_year;

printf("Enter the lowest year: ");

scanf("%d",&min_year);

printf("Enter
the heighest year: ");

scanf("%d",&max_year);

printf("Leap
years in given range are: ");

for(year = min_year;year <= max_year; year++){

if(((year%4==0)&&(year%100!=0))||(year%400==0))

printf("%d
",year);

}

return 0;

}

Sample output:

Enter the lowest year: 2000

Enter the highest year: 2011

Leap years in given range is:
2000 2004 2008

thanks a lot

ReplyDeleteplease make a change of if statement

ReplyDeleteif(((year%4==0)&&(year%100!=0))||(year%400==0))

Great work :) thanks a lot.. my doubt got cleared ...

ReplyDeletethanks a lot

ReplyDeleteexplain?

ReplyDeletegreat job yarrrr

ReplyDeleteYOU CAN TRUNCATE THE MIDDLE PART NUM%100 BECAUSE THERE ARE SOME LEAP WHOSE MODULUS ARE EQUAL TO HUNDERED

ReplyDeletewhy dont u write it as year%4==0

ReplyDeleteit means year divided by 4 leaves remainder 0..

is it correct?

Exactly!!

Deletecan u help me do it without using if statement

ReplyDeletewrite a c program swapping of to no with out using third variable & with out using addition & substracting?

ReplyDeleteGo though this link:

DeleteSWAP TWO VARIABLES WITHOUT USING THIRD USING C PROGRAM VARIABLE

thanks a lot ritesh

ReplyDelete1500 and 1700 are leap years...

ReplyDeleteyou mentioned that it is not a leap year...

From wiki: 1600 was a leap year, but 1700, 1800 and 1900 were not.

DeleteTo understand concept of leap year I hope this link will help you: Concept of leap year

i hav a doubt...anybody can clear tis pls??? is thr any need to divide a year by 100?? y r v using tat???

ReplyDeleteI hope this will helpful ..

Delete1600, 2000 etc leap year while 1500, 1700 are not leap year.

// if we enter 1500

if ( ( (year%4==0) && (year%100!=0)) || (year%400==0) )

{

// according to this 1500 not a leap year..

}

-----------------------------------

if ( (year%4==0) || (year%400==0) )

{

// according to this 1500 a leap year..

}

very useful

ReplyDeletethanx bud!

ReplyDeletecan you do same program without using any logical operator?

ReplyDeleteNice Explanation available in this : http://www.youtube.com/watch?v=1x-oBF3vgk0&list=PLPgpWDN1BdTvWebvqTXQie6yIjx6yOXFZ&index=2

ReplyDeleteint main(){

ReplyDeleteint year;

printf("Enter any year: ");

scanf("%d",&year);

if(((year%4==0)&&(year%100!=0))||(year%400==0))

printf("%d is a leap year",year);

else

printf("%d is not a leap year",year);

return 0;

}

..............................................................

I think it's a wrong code.

when I try 2200 it shows that the year isn't leap year.

...............................................................

I think the code will be,

int main(){

int year;

printf("Enter any year: ");

scanf("%d",&year);

if(year%4==0)

printf("%d is a leap year",year);

else

printf("%d is not a leap year",year);

return 0;

}

..........................................................................

If I'm wrong , please explain......
