Determining Whether a Year is a leap year:

Added: year → eg (2004.2005, etc.)
Output: leap Has the program:
1. Class
2. Constructors
3. Operator overloading I / O
# Include <cstdlib>
# Include <iostream>
using namespace std;

friend ostream & operator <<(ostream &, intercalary &); 
 public:

int process () {return result = n% 4;};
private:
int n;
int result;
};

court <<"enter the year:";
