C++ program
Hi i need help making the following function,
------>>>>>> friend bool operator<(Date& date1, Date& date2);
the function is supposed to compare 2 date objects of the Date class ...............................
It is supposed to overload the < operator to compare 2 Date objects. The comparison shall return true only if the Date object on the left represents a date earlier than the Date object on the right. The comparison shall not update
either Date object.
please help I provided all my code below:
The following are the 3 libraries of my program
---------------------------------------------------------------------------------------------------------------------------------------------------------
DATE.H file:
#ifndef DATE_H
#define DATE_H
#include <string>
using namespace std;
class Date {
private:
string entered_date;
int month_, day_, year_;
public:
Date();
Date(const string& entered_date);
friend bool operator<(Date& date1, Date& date2);
friend istream& operator >>(istream& input, Date& d);
friend ostream& operator<<(ostream& output, Date& d);
};
#endif

cout << "Please enter a date in 03/24/1990 format:" << endl;
input >> d.entered_date;
return input;
}
Date::Date(const string& entered_date) {
month_ = stoi(entered_date.substr(0, 2));
day_ = stoi(entered_date.substr(3, 2));
year_= stoi(entered_date.substr(6));
cout << month_ << endl << day_ << endl << year_;
}
