C++ Date Class with Operator Overloading

The following program defines a date class in C++ that calculates the difference between two dates, adds a number of days to a date, and handles leap years correctly.

Source Code

#include<iostream.h>
#include<conio.h>
#include<process.h>

class date
{
private:
    int flag, day, month, year;
public:
    date(int d, int m, int y)
    {
        day = d, month = m, year = y;
        if (year % 4 == 0)
            flag = 1;
        else
            flag = 0;
    }
    int operator-(date d2);
    date operator+(int n);
    int operator>(date d2);
    friend ostream& operator<<(ostream& out, date d1);
    int return_integer_date(date d1);
};

Partition Table Reader and Hide/Reveal Tool

Release date: 1.1.2006

About the Program

This program is a part of my project to read the ext2 Linux file system under DOS or Windows 98. It reads the partition table of your hard disk, prints information about each partition, and can hide and reveal partitions by changing the system ID of those partitions.

Caution

Modification of the code may make your disk unusable. The author is not responsible for any damage or data loss.

Compatibility and Compilation

• This program is tested under Windows 98.
• Compile it with Turbo C 3.
