could you show us what you tried?

write a date function that Receipt a number ( for example 1267859 )
and turn it to a date ( for example 2014/10/2 ).

sorry I couldn't get that one... Is the receipt number anyway related to date?

look with this function we turned a date to DAYS...this function show us the number of days.

void Date :: inDays()   
{
	unsigned long d = 0;
	cout<<"\n\n"<<(year - 1200 ) * 365 +
	(month - 1 ) * 30 +
	day<<"\n\n";
	
}

now i want a formula that do this Vice versa for example we give it the number of the days ( like 852164) and it give us the date of it .
