Debug this Please. ( C, C++ Mixup)

I just recently(as in a few hours ago) decided to take up a small program my dad put up for me. It's the N-Queens Problem(Google it).

The code is below. Now I know that the code is pretty redundant but I honestly don't care too much about that.

Code:

`#include <iostream.h>`

#include <conio.h>

#include <math.h>

int b[8][8];

void setzero(int x)//This sets the remaining non-conflicted spaces in the board to zero. x is the row number.

{

int v,w;

for (v=x;v<=8;v++)

{

for (w=1;w<=8;w++)

{

if(b[v][w]>=x)

b[v][w]=0;

}

}

}

void options(int y,int z)//This function is just to remove the places on the board which are crossed out by any one queen.

{

int d,e,f,g;

for (d=1;d<=8;d++)//Getting the row.

if (b[d][z]!=9)

if (b[d][z]==0)

b[d][z]=y;

for (e=1;e<=8;e++)//Getting the Column.

if (b[y][e]!=9)

if (b[y][e]==0)

b[y][e]=y;

for (f=1;f<=8;f++)//For the diagonals.

for (g=1;g<=8;g++)

{

if ((f+g)==(y+z))

{if (b[f][g]==0)

b[f][g]=y;

}

else if(fabs(f-g)==fabs(z-y))

{

if (b[f][g]==0)

b[f][g]=y;

}

}}

void main()

{

int i,j,k,l,m,n,o,p,q,r,s,t,u,v,w;

//Declaring a buttload of variables.

for (i=1;i<=8;i++)//Row 1

{

int ctr = 1;

setzero(ctr);

b[1][i]=9;

options(1,i);

for(j=1;j<=8;j++)//Row 2

{

ctr = 2;

setzero(ctr);

if (b[2][j] == 0)

{

b[2][j]=9;

options(2,j);

for(k=1;k<=8;k++)//Row 3

{

ctr = 3;

setzero(ctr);

if(b[3][k]==0)

{

b[3][k]=9;

options(3,k);

for(l=1;l<=8;l++)//Row 4

{

ctr = 4;

setzero(ctr);

if (b[4][l]==0)

{

b[4][l]=9;

options(4,l);

for(m=1;m<=8;m++)//Row 5

{

ctr = 5;

setzero(ctr);

if (b[5][m]==0)

{

b[5][m]=9;

options(5,m);

for(n=1;n<=8;n++)//Row 6

{

ctr = 6;

setzero(ctr);

if (b[6][n]==0)

{

b[6][n]=9;

options(6,n);

for(o=1;o<=8;o++)//Row 7

{

ctr = 7;

setzero(ctr);

if (b[7][o]==0)

{

b[7][o]=9;

options(7,o);

for(p=1;p<=8;p++)//Row 8

{

ctr = 8;

setzero(ctr);

if (b[8][p]==0)

{

b[8][p] = 9;

s=0;

for(q=1;q<=8;q++)//To check whether i got a solution at all or not. Solution means 8 queens should be there on the board. S is the number of queens.

{

for(r=1;r<=8;r++)

{

if (b[q][r]==9)

s=s+1;

}

}

if (s == 8)

{

for (t=1;t<=8;t++)//If 8 queens are there, this prints the column number in each row seperated with a '-'.

for (u=1;u<=8;u++)

if (b[t][u]==9)

cout<<u<<"-";

}}}}}}}}}}}}}}}}}

Now I'm not getting any compile errors but when I try to run the program, it just blinks out and then comes back to the same screen. Try running this in your C++ Compiler. I don't get an output. I'm not getting any errors either.

EDIT: Code edited.

Any ideas?
