Given a year we have to find whether the year is leap year or not .
so what is leap year?
leap year are the year if it follow these two condition:
1-year is multiple of 400.
2-year is multiple of 4 but not multiple of 100.
Example:
input:2000
output:leap year
input:1600
output:leap year.
Logic:
we have to check two condition to be a year to leap year.
1-year is multiple of 400.
2-year is multiple of 4 but not multiple of 100.# include <bits/stdc++.h>
using namespace std;
bool isleap(int year)
{
if(year%400==0)
{
return true;
}
if(year %4==0&&year%100!=0)
{
return true;
}
return false;
}
int main()
{
int year;
cout<<"enter Year"<<endl;
cin>>year;
if(isleap(year)==true)
{
cout<<year<<" is a leap year"<<endl;
}
else
{
cout<<year<<" is not a leap year"<<endl;
}
}
Output:
enter year : 1600 1600 is a leap year
