How to output Dates?

[andrewama]

Hey guys i was just wondering i have a code that will allow you to output times 4 different ways but instead of times i want it to output dates 4 different ways.

#include <iostream>
using std::cout;

#include <iomanip>
using std::setfill;
using std::setw;
using std::endl;

#include "Time.h" // include definition of class Time from Time.h


#
int main()
{
Time t1; // all arguments defaulted
Time t2( 2 ); // hour specified; minute and second defaulted
Time t3( 21, 34 ); // hour and minute specified; second defaulted
Time t4( 12, 25, 42 ); // hour, minute and second specified
Time t5( 27, 74, 99 ); // all bad values specified

 

cout << "Constructed with:\n\nt1: all arguments defaulted\n ";

t1.printUniversal(); // 00:00:00

cout << "\n ";

t1.printStandard(); // 12:00:00 AM
 
cout << "\n\nt2: hour specified; minute and second defaulted\n ";

t2.printUniversal(); // 02:00:00

cout << "\n ";

t2.printStandard(); // 2:00:00 AM

 

cout << "\n\nt3: hour and minute specified; second defaulted\n ";

t3.printUniversal(); // 21:34:00

cout << "\n ";

t3.printStandard(); // 9:34:00 PM

 

cout << "\n\nt4: hour, minute and second specified\n ";

t4.printUniversal(); // 12:25:42

cout << "\n ";

t4.printStandard(); // 12:25:42 PM

 

cout << "\n\nt5: all invalid values specified\n ";

t5.printUniversal(); // 00:00:00

cout << "\n ";

t5.printStandard(); // 12:00:00 AM

cout << endl;
system("pause");
return 0;

} // end main
// Time constructor initializes each data member to zero;
// ensures that Time objects start in a consistent state
Time::Time( int hr, int min, int sec ) 
{ 
   setTime( hr, min, sec ); // validate and set time
} // end Time constructor

// set new Time value using universal time; ensure that
// the data remains consistent by setting invalid values to zero
void Time::setTime( int h, int m, int s )
{
   setHour( h ); // set private field hour
   setMinute( m ); // set private field minute
   setSecond( s ); // set private field second
} // end function setTime

// set hour value
void Time::setHour( int h )
{
   hour = ( h >= 0 && h < 24 ) ? h : 0; // validate hour
} // end function setHour

// set minute value
void Time::setMinute( int m )
{
   minute = ( m >= 0 && m < 60 ) ? m : 0; // validate minute
} // end function setMinute

// set second value
void Time::setSecond( int s )
{
   second = ( s >= 0 && s < 60 ) ? s : 0; // validate second
} // end function setSecond

// return hour value
int Time::getHour()
{
   return hour;
} // end function getHour

// return minute value
int Time::getMinute()
{
   return minute;
} // end function getMinute

// return second value
int Time::getSecond()
{
   return second;
} // end function getSecond

// print Time in universal-time format (HH:MM:SS)
void Time::printUniversal()
{
   cout << setfill( '0' ) << setw( 2 ) << getHour() << ":"
      << setw( 2 ) << getMinute() << ":" << setw( 2 ) << getSecond();
} // end function printUniversal

// print Time in standard-time format (HH:MM:SS AM or PM)
void Time::printStandard()
{
   cout << ( ( getHour() == 0 || getHour() == 12 ) ? 12 : getHour() % 12 )
      << ":" << setfill( '0' ) << setw( 2 ) << getMinute()
      << ":" << setw( 2 ) << getSecond() << ( hour < 12 ? " AM" : " PM" );
} // end function printStandard

here is the header

// Fig. 9.8: Time.h
// Declaration of class Time.
// Member functions defined in Time.cpp.

// prevent multiple inclusions of header file
#ifndef TIME_H
#define TIME_H

// Time abstract data type definition
class Time 
{
public:
   Time( int = 0, int = 0, int = 0 ); // default constructor

   // set functions
   void setTime( int, int, int ); // set hour, minute, second
   void setHour( int ); // set hour (after validation)
   void setMinute( int ); // set minute (after validation)
   void setSecond( int ); // set second (after validation)

   // get functions
   int getHour(); // return hour
   int getMinute(); // return minute
   int getSecond(); // return second

   void printUniversal(); // output time in universal-time format
   void printStandard(); // output time in standard-time format
private:
   int hour; // 0 - 23 (24-hour clock format)
   int minute; // 0 - 59
   int second; // 0 - 59
}; // end class Time

#endif

Yes you could rewrite the program to handle dates instead of time. You would need to determine the format(s) you want first. Then start with the basics and write just one function/method at a time, testing as you go. You can post post pertinent code, error messages and questions about a specific problem you can't figure out when you run into them.
