Help with the code!! Urgent

I need to set the cells with the distance from the center such that val[center]=0.
Eg:
4 3 2 3 4
3 2 1 2 3
2 1 0 1 2
3 2 1 2 3
4 3 2 3 4

Code:
1
2
3
4
5
6
7

10

#include<iostream>
#include<cstdio>
#include<conio.h>
#include<algorithm>
using namespace std;
void pushNeighbours(int);
void pushCrtLvl(int, int);
int mat[5][5],crtLvl[25][2],nxtLvl[25][2],top=0,top1=0,level=0;
using namespace std;
int main()
{
 int i,j,count=0;
 for(i=0;i<5;i++)
 fill_n(*(mat+i),5,255);
 crtLvl[0][0]=crtLvl[0][1]=2;
 top++;
 while(top!=0)
 {
  if(mat[crtLvl[top-1][0]][crtLvl[top-1][1]]==255)
  {
   mat[crtLvl[top-1][0]][crtLvl[top-1][1]]=level;
   count++;
   pushNeighbours(top-1);
  }   
  top-=1;
  if(top==0)
  {
  level++;
  top=top1;
  for(i=0;i<top1;i++)
  copy(nxtLvl[i],nxtLvl[i]+2,crtLvl[i]);
  top1=0;
  for(i=0;i<25;i++)
  fill_n(*(nxtLvl+i),2,0);
  }
  if(count==25)
  {
  break;
  }
 } 
 for(i=0;i<5;i++)
 {
  for(j=0;j<5;j++)
  cout<<mat[i][j]<<" ";
  cout<<'\n';
  }
  getch();
}
void pushNeighbours(int crt)
{
pushCrtLvl(crtLvl[crt][0],(crtLvl[crt][1]+1));
pushCrtLvl((crtLvl[crt][0]+1),crtLvl[crt][1]);
pushCrtLvl(crtLvl[crt][0],(crtLvl[crt][1]-1));
pushCrtLvl((crtLvl[crt][0]-1),crtLvl[crt][1]);
} 
void pushCrtLvl(int r,int c)
{
 if((r<5 & r>=0)&(c<5 & c>=0))
 {
  nxtLvl[top1][0]=r;
  nxtLvl[top1][1]=c;
  ++top1;
 }
}

My code is working fine till count=13(upto level 2)(top is not giving correct value) but after that its failing(top value isnt working)

Before anything else it will be much easier for people to read/understand this if you can put Code tags around everything.
