Problems with switch statement

[dontcare]

This program displays the information of an input file containing dates and strings, the output is in the following form On day, January 1, 1800 The first day begins. [number of days since 1/1/1800; (1)]. My problem is implementing a correct switch statement to display the Day of the week. The day ot the week is found using the number of days since 1.1.1800, here's the code and an attached file. Also I' not sure if the correct output in the number of days is right. If someone could check my code, I would appreciate it.

#include <iostream>
#include <fstream>
#include <cstdlib>
#include <cstring>
#include <iomanip>
using namespace std;

// DaysFrom1800 Class Definition
	class DaysFrom1800 {
	public:
	DaysFrom1800();
	int numDaysFrom1800 (int day, int month, int year);
	int fillDaysArray (int numberOfDates, int day[], int month[], int year[], string textArray[], DaysFrom1800 numbers []);
	void DaysFrom1800::printDaysSince1800 () {
	cout << daysSince;
	}


	private:
	int daysSince;
	};

// Prototypes
	bool leapCheck (int year);
	void prettyPrint (int numberOfDates, string textArray[], DaysFrom1800 numbers[], int month[], int day[], int year[]);


	int main () {

		int year [200];
		int numberOfDates = 0;
		DaysFrom1800 numbers[200];
		DaysFrom1800 dummy;
		string textArray [200];

		numberOfDates = dummy.fillDaysArray (numberOfDates, day, month, year, textArray, numbers);

		prettyPrint(numberOfDates, textArray, numbers, month, day, year );
		return 0;
		}
	int DaysFrom1800::fillDaysArray (int numberOfDates, int day[], int month[], int year[], string textArray[], DaysFrom1800
	numbers []) {

		ifstream inStream;
		inStream.open("io.txt");

I fixed one error in the switch statement, it should be 0-6, wen. is the first day (1,1,1800). But my problem still isn't fixed, the output is a repeated day, "Sunday". The program should execute the number of days since 1/1/1800 and then divide that number by 7, and finally use the remainder as the switch for the correct output. (%) Please help, need to turn program in today. My next assignment is due Friday and I need this program completed first before preceding to it.

switch (numberOfDates% 7) {
                        case 1:cout <<  "Wenesday"; break;
                        case 2: cout << "Thursday"; break;
                        case 3: cout<< "Friday"; break;
                        case 4: cout<< "Saturday"; break;
                        case 5: cout<< "Sunday"; break;
                        case 6: cout<<"Monday"; break;
                        case 0: cout<<"Tuesday"; break;
                        }

// Prototypes
        bool leapCheck (int year);
        void prettyPrint (int numberOfDates, string textArray[], 		  DaysFrom1800 numbers[], int month[], int day[], int year[]);

Needed to be put into public and made friend functions. In order to use the switch statement for days. The switch should of have been daysSince and not what I had.

for (int i=0; i<numberOfDates; i++) {
cout << "On " ;
switch (numbers[i].daysSince % 7) {
case 1:cout <<	"Wednesday"; break;
case 2: cout << "Thursday"; break;
case 3: cout<< "Friday"; break;
case 4: cout<< "Saturday"; break;
case 5: cout<< "Sunday"; break;
case 6: cout<<"Monday"; break;
case 0: cout<<"Tuesday"; break;

}

Now i need to work on the computational errors I made.
