Class Example: Constructor With Default Arguments

#include <iostream.h>
/********************************************************
 File: class4a.C
 Instantiate a date class, initialize two date objects,
 and print them. The initialization is done using
 a constructor with default arguments
*********************************************************/

class time {
     int hours;
     int mins;
     int secs;
public:
     time(int h=12 , int m=0 , int s=0 );
     void print();
};

time::time(int h, int m, int s)
{
	cout << "Calling default time constructor..." << endl;
	hours = h;
	mins = m;
	secs = s;
}

void time::print()
{
     cout << "The time stored in this object is:" << endl;
     cout << "Hours: " << hours << endl;
     cout << "Minutes: " << mins << endl;
     cout << "Seconds: " << secs << endl;
}

typedef time Time;

int main()
{
     int hours, minutes, seconds;

     cout << "Enter the time in HH MM SS format: ";
     cin >> hours >> minutes >> seconds;

     Time now( hours, minutes, seconds);
     now.print();
    
     Time then;
     then.print();

     exit(0);

}

Output:

Enter the time in HH MM SS format: 12 35 42
Calling time constructor...
The time stored in this object is:
