Goto and Backtracking

[ai3dunks]

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.

There is more to the project but I'm not asking for that much help. 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
int a[n]={};
int b[n]={};
int c[n]={};
int x=0;



int main()
{


testA:
    for(int i=0; i<n;i++)        // check for consecutive days
    {
        if(a[i]==0)
        {
            a[i]=1;
            i++;
        }
        else
            a[i+1]=0;
    }

testB:
    for(int i=0; i<n;i++)        // check for consecutive days
    {
        if(b[i]==0)
        {
            b[i]=1;
            i++;
        }
        else
            b[i+1]=0;
    }   
    for(int i=0; i<n;i++)        //checks to see if Docter B is working same shift with Docter A
    {
        if(b[i]==1 && a[i]==1)
        {
            b[i]=0;
            b[i+1]=1;
        }
    }

testC:
    for(int i=0; i<n;i++)        // check for consecutive days
    {
        if(c[i]==0)
        {
            c[i]=1;
            i++;
        }
        else
            c[i+1]=0;
    }   
    for(int i=0; i<n;i++)        //checks to see if Docter C is working same shift with Doctor B and Doctor A
    {
        if((c[i]==1 && b[i]==1) || (c[i]==1 && a[i]==1))
        {
            c[i]=1;
            c[i+1]=0;

        }
    }

    goto print;

backtrack:
    goto testA;

print:
    for(int i=0; i<n;i++)    //Prints line A
    {
        cout << a[i];
    }

    cout<<endl;

    for(int i=0; i<n;i++)    //Prints line B
    {
        cout << b[i];
    }

    cout<<endl;

    for(int i=0; i<n;i++)    //Prints line C
    {
        cout << c[i];
    }

    cout << endl;
    return 0;
}

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 some assistance on 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

I am not asking for anyone to do my final project for me. Just asking for any useful tips.
