Assignment 1

Problem Statement

This assignment requires you to write code to manipulate dates and perform date arithmetic. The main functional requirements are as follows:

The program must prompt the user to input two dates in mm dd yyyy format
The program must validate the dates to make sure it conforms to normal range of values
The program must verify that the first date is chronologically earlier (or the same as) the second date
If the above two items are satisfied, the program must compute and display the number of days elapsed between the two dates. Your program must accomodate leap years

Design Recommendation

Design your application using the following two classes:


class Date{
public:
	Date(); // initialize attributes with default values	
	bool setDate();	/* assign values to Date attributes, 
			return true iff valid range of values are input */
	void getDate(int& , int& , int&); // retrieve Date attribute values
	void showDate(); // Display Date attribute values
	// All other relevant methods go here
private:
	bool validateDate(); // Validate attribute range values
	int Day;
	int Month;
	int Year;
};

class DateCalculator{
public:
	int daysBetween(Date& , Date& ); // return days elapsed between two Dates
	bool isEarlier(Date& D1, Date& D2); /* return true if D1 is earlier
				            or same as D2 otherwise return false */
	// All other relevant methods go here
private:
	// All relevant attributes go here
};

using namespace std;
#include <iostream>
#include "Date.h"
#include "DateCalculator.h"

int main(){
	Date d1, d2;
	DateCalculator dc;
	char quit = 'n';

	while(quit != 'y'){
		if(d1.setDate() && d2.setDate()){
			if(dc.isEarlier(d1, d2)){
				cout << "Days elapsed between ";
				d1.showDate();
				cout << "and ";
				d2.showDate();
				cout << "is " << dc.daysBetween(d1, d2) << endl;
			}  //end if
			else {
				cout << "ERROR: Invalid chronological dates" << endl;
				continue;
			} //end else
		} // end if
		
		cout << "Quit (y/n)? ";
		cin >> quit;
		
	} // end while

	return(0);
} // end main

Write your class definitions in file asg1.h , your class method implementations in file asg1.C, and the main() function in file asg1_main.C . Copy your files into your subdirectory under the /accounts/classes/subraman/ba6806 subdirectory. The deadline for this project is 3/03/2005
