C++ :: Back Tracking And Goto Functions

I have a project where I have to schedule 3 doctors for 28 days. Doc A, B, and C. The rules are:

1. They can't work back to back, but only on weekends. Example Doc. A can't work Monday and Tuesday, If Doc. A works Saturday, he must work Sunday also.
2. Doc. A and B work alternate weekends.
3. Doc. C can't work Tuesday or weekends.

I'm trying to base my project off of the 8 Queens program that uses backtracking and the goto function. Right now, I'm just trying to get my program to print this

100100100
010010010
001001001

Here is my goto Code

#include "stdafx.h"
#include <iostream>
#include<iostream>
using namespace std;
void print();
#define n 28 //28 day schedule
int a[n]={};

[Code] ....

If you look at my code you will notice that it prints out like this, where array c doesn't take in account for array a.

1010101010101
0101010101010
1010101010101

I need getting the program to modify a[], b[], and c[] when necessary. I should be able to change any array element to '1' and it will automatically fill in the schedule by itself. example

010001000101001
100100101010010
001010010000100
