Write a C++ Program to Find Year is leap Year with an example. In this leap year example, we used the If statement to check whether
- year % 400 equals 0 – Year divisible by 400 is a leap.
- ( year % 4 == 0 ) && ( year % 100 != 0)) – Any year divisible by 4 and that is a century year, then it is a leap.
#include<iostream>
using namespace std;
int main()
{
int year;
cout << "\nPlease Enter the Year to Check the Leap Year = ";
cin >> year;
if (( year % 400 == 0) || (( year % 4 == 0 ) && ( year % 100 != 0)))
{
cout << "\n" << year << " is a Leap Year";
}
else
{
cout << "\n" << year << " is Not a Leap Year";
}
return 0;
}

Let me check with another.
Please Enter the Year to Check the Leap Year = 2020
2020 is a Leap Year
The below Program accepts the integer and Finds whether it is a leap Year or not using Else If statement.
#include<iostream>
using namespace std;
int main()
{
int year;
cout << "\nPlease Enter the Year to Check = ";
cin >> year;
if (year % 400 == 0)
{
cout << "\n" << year << " is a Leap Year";
}
else if ( year%100 == 0)
{
cout << "\n" << year << " is Not a Leap Year";
}
else if ( year % 4 == 0 )
{
cout << "\n" << year << " is a Leap Year";
}
else
{
cout << "\n" << year << " is Not a Leap Year";
}
return 0;
}
Please Enter the Year to Check = 2024
2024 is a Leap Year
This Program helps to check Year is a leap Year using the Nested If statement.
#include<iostream>
using namespace std;
int main()
{
int year;
cout << "\nPlease Enter the Year to Check = ";
cin >> year;
if(year % 4 == 0)
{
if( year % 100 == 0)
{
if ( year % 400 == 0)
{
cout << "\n" << year << " is a Leap Year";
}
else
{
cout << "\n" << year << " is Not a Leap Year";
}
}
else
{
cout << "\n" << year << " is a Leap Year";
}
}
else
{
cout << "\n" << year << " is Not a Leap Year";
}
return 0;
}
Please Enter the Year to Check = 2016
2016 is a Leap Year
