Date

I would like to make a program that will read dates under the formate dd mm yy and output it to gregorian style : day of the week, month dd yyyy. Program must be able to read dates from a file as far back as january1 1990, or 01 01 1990 to today, and must use the 2 following function files:

CPP / C++ / C Code:
#include <iostream.h>


enum oneDay { monday=1, tuesday, wednesday, thursday, friday, saturday, sunday } ;


oneDay Successor( oneDay day )
{
	
	if( day == sunday)
		return monday ;
	else
        return oneDay(   int(day) + 1 ) ;
}

oneDay Predecessor( oneDay day)
{
	if( day == monday )
		return sunday ;
	else
		return oneDay(   int(day) - 1 ) ;

}


int Intconverter( oneDay internalday )
{
	// internaly :		1 == monday, 2 == tuesday, 3 == wednesday, ..., 7 == sunday.
	return  int(internalday) ;
	// users :	1 == monday, 2 == tuesday, 3 == wednesday, ..., 7 == sunday.
}

oneDay convertIntto_oneDay( int dayuser )
{
	// users :	1 == monday, 2 == tuesday, 3 == wednesday, ..., 7 == sunday.
	return  oneDay( dayuser  ) ;
	// internaly :		1 == monday, 2 == tuesday, 3 == wednesday, ..., 7 == sunday.
}



void   showday( oneDay date )
{
	switch( date )
	{
	case monday : 
			cout << "monday" ;
			break ;
	case tuesday :
			cout << "tuesday" ;
			break ;
	case wednesday :
			cout << "wednesday" ;
			break ;
	case thursday :
			cout << "thursday" ;
			break ;
	case friday :
			cout << "friday" ;
			break ;
	case saturday :
			cout << "saturday" ;
			break ;
	case sunday :
			cout << "sunday" ;
	}
}
CPP / C++ / C Code:
#include <iostream.h>


enum oneMonth {	january=1,	february,	march,		april,		may,		june, 
				july,	august,		september,	october,	november,	december
			} ;



oneMonth Successor( oneMonth month )
{
	if( month == december )
		return january ;
	else	
		return oneMonth(   int(month) + 1 ) ;
}


oneMonth Predecessor( oneMonth month )
{
	if( month == january )
		return december ;
	else
		return oneMonth(   int(month) - 1 ) ;
}


int Intconverter( oneMonth monthInternal )
{
	// Internal :		1 == january, 2 == february, 3 == march, ..., 12 == december.
	return  int(monthInternal) ;
	// Users :	1 == january, 2 == february, 3 == march, ..., 12 == december.
}


oneMonth ConvertIntto_oneMonth( int MonthUser )
{
	// Users :	1 == january, 2 == february, 3 == march, ..., 12 == december.
	return  oneMonth( monthUser  ) ;
	// Internal :		1 == january, 2 == february, 3 == march, ..., 12 == december.
}




void   showmonth( oneMonth monthnumber )
{
	switch( monthnumber )
	{
	case january : 
			cout << "january" ;
			break ;
	case february :
			cout << "february" ;
			break ;
	case march :
			cout << "march" ;
			break ;
	case april :
			cout << "april" ;
			break ;
	case may :
			cout << "may" ;
			break ;
	case june :
			cout << "june" ;
			break ;
	case july :
			cout << "july" ;
			break ;
	case august :
			cout << "august" ;
			break ;
	case september :
			cout << "september" ;
			break ;
	case october :
			cout << "october" ;
			break ;
	case november :
			cout << "november" ;
			break ;
	case december :
			cout << "december" ;
	}
}

Problem is im not really sure how to incoperate it. I know how to read data from a file, then these programs will work on it, and then i can output the results, but how to get the to work is where i get stuck.

Not sure. I did not look that close at the code.

Yes that is it.

I would say forget the file stuff for now. Start by picking one part of the date. Say the month. In your Example of "01 01 1990" it would be 1. So that is entered as an int. Now just look for the function that will convert an "int" to a type "oneMonth". So you are looking for a function that takes an int as a argument/parameter and returns a type "oneMonth". Do you see one that does that(oneMonth ConvertIntto_oneMonth( int MonthUser )? Write the code for main so that works/gives the results you want then move onto the next part you want to get working.
ect ect ...

That notation tells the compiler to look in its installation directories for the header. The easiest way to tell the compiler to look into the same directory (where the source file is), is to use

CPP / C++ / C Code:
#include "oneMonth.h"

At least it found the file, and that's a Good Thing, right?

However...

Showing us the error messages that came from onemonth.h without showing us what's in the file is not likely to be productive. Post the code.

Regards,

Dave
