Implement the operator +=, -=, +, -, in the class Date
class Date
{
public:
Date(int y=0, int m=1, int d=1);
static bool leapyear(int year);
int getYear() const;
int getMonth() const;
int getDay() const;
// add any member you need here
};
You implementation should enable the usage like this:
void f()
{
Date date = d;
cout << "date = " << date << endl;
cout << "date+1 = " << date+1 << endl;
cout << "date-1 = " << date-1 << endl;
date+=366;
cout << "date = " << date << endl;
date-=365;
cout << "date = " << date << endl;
date-=-365;
cout << "date = " << date << endl;
date+=-366;
cout << "date = " << date << endl;
cout << endl;
}
The output of f() should be:
date = 2004-2-28
date+1 = 2004-2-29
date-1 = 2004-2-27
date = 2005-2-28
date = 2004-2-29
date = 2005-2-28
date = 2004-2-28
