Count the days of the week

Posted 16 January 2009 - 03:26 PM

My program runs fine. The only thing is that this code

cout<<"Five Days from today will be: ";
		dayOne.addDays("Wedsnday", 5);


doesn't show. I don't know what went wrong. Can anyone figure out where I went wrong?

#include "stdafx.h"
#include <iostream>
#include <string>

using namespace System;
using namespace std;

class DaysOfTheWeek
{
	private:
		string day;
		string mon;
		string tue;
		string wed;
		string thur;
		string fri;
		string sat;
		string sun;
		
				
	public:
		//constructors
		 DaysOfTheWeek();
		 DaysOfTheWeek(string);

			//Functions
			void setDay (string);
			void printDay (void);
			string getDay (void);
			void nextDay (string);
			void previousDay (string);
			void plusOneDay (int);
			void minusOneDay (int);
			void addDays (string, int);

};

int main()
{
	cout<<"Days of the week"<<endl;

	//Displays for Day 1
		cout<<"** Day 1 **"<<endl;
	DaysOfTheWeek dayOne;
	dayOne.setDay("Wedsnday");
	dayOne.getDay();

	cout<<"Today is :"; 	
	dayOne.printDay();

	cout<<"Yesterday was: ";
		dayOne.previousDay("Wedsnday");

	cout<<"Tomorrow will be: ";
		dayOne.nextDay("Wedsnday");

	cout<<"Five Days from today will be: ";
		dayOne.addDays("Wedsnday", 5);
		
		cout<<endl;
	//Displays for Day 2 
		cout<<"** Day 2 **"<<endl;
	DaysOfTheWeek dayTwo("Sunday");
	dayTwo.setDay("Sunday");
	dayTwo.getDay();

	cout<<"Today is :";
	dayTwo.printDay();

	cout<<"Yesterday was: ";
		dayTwo.previousDay("Sunday");
	
	cout<<"Tomorrow will be: ";
		dayTwo.nextDay("Sunday");

	cout<<"Two Days from today will be: ";
		dayTwo.addDays("Sunday", 2);
	
		cout<<endl;
	
	return 0;
}

Change all these:
cout<<"Five Days from today will be: ";
    dayOne.addDays("Wedsnday", 5);


to
cout<<"Five Days from today will be: " 
        << dayOne.addDays("Wedsnday", 5);


And it's "Wednesday", not "Wedsnday".

Your code for "addDays" made my eyes bleed.

Consider two things that would make this far simpler, and smaller. One is a seven element string array for the day names. The other is to use a number (0..6) to internally represent your values.

That still didn't work. I'm not understanding why dayTwo.addDays works and dayOne.addDays doesn't. Any other suggestions?

My eyes bled too.
The best thing you should do is exactly what baavgai suggested, if will make your code much smaller, and much more flexible.

Code such as this:

#include <iostream>
#include <string>

using namespace std;

string days[7] = 
{
	"Monday",
	"Tuesday",
	"Wednesday",
	"Thursday",
	"Friday",
	"Saturday",
	"Sunday"
};

string nextDay(string day, int num)
{
	// SEARCH THE STRING
	for (int i = 0; i < 7; i ++)
	{
		if (days[i] == day)
			// RETURN THE DAY
			return days[(364 + i + num) % 7];
	}
}
	
int main()
{
	cout << nextDay("Wednesday", 5) << endl;
	cout << nextDay("Wednesday", -5);
	cin.ignore();
	return 0;
}

Now isn't that much more eyepleasing? And it also works with negative values of num
