print a table of decremented numbers - c++

Question

I want to write a code that print a table like this:
5 5 5 5 5 5 5 5 5
5 4 4 4 4 4 4 4 5
5 4 3 3 3 3 3 4 5
5 4 3 2 2 2 3 4 5
5 4 3 2 1 2 3 4 5
5 4 3 2 2 2 3 4 5
5 4 3 3 3 3 3 4 5
5 4 4 4 4 4 4 4 5
5 5 5 5 5 5 5 5 5
I wrote a code to print a table as said above, but it just print 5's.
I know that I have to use a condition to print such a table. What's the condition to print it ?
int main () {
int number = 5;
for (int i = 0; i < 9; i++) {
for (int j = 0; j < 9; j++) {
if (condition)
...
else
cout << number << " ";
}
cout << endl;
}
return 0;
}

As I mentioned in comments, what you want to print is the Chebyshev distance to the center +1. I dont know what condition can make your code work, but instead I would use a simple formula to calculate each value:
#include <iostream>
using namespace std;
int main() {
for (int i=0;i<9;i++){
for (int j=0;j<9;j++){
cout << std::max(abs(i-4),abs(j-4)) +1 << " " ;
}
cout << endl;
}
}

/*To make boxes and inside box and so on
#include<stdio.h>
#include<conio.h>
#include<iostream.h>
void main()
{
int a[100][100],n,i,j,k=0,l;
clrscr();
cout<<"Enter the outside No. n \n";
//like for your answer it is 5;
//i and j are loop element for 2D array
//k is used for making n boxes
cin>>n;
l=n;
n=2*n-1;
while(k<n)
{
if(k%2==0)
{
for(i=k;i<n-k;i++)
{
a[0+k][i]=l;
a[i][0+k]=l;
a[n-1-k][i]=l;
a[i][n-1-k]=l;
}
k++;l--;
}
else
{
for(i=k;i<n-k;i++)
{
a[0+k][i]=l;
a[i][0+k]=l;
a[n-1-k][i]=l;
a[i][n-1-k]=l;
}
k++;l--;
}
}
for(i=0;i<n;i++)
{
for(j=0;j<n;j++)
{
cout << a[i][j];
if(a[i][j]>9)
cout<<" ";
else
cout<<" ";
}
cout<<endl;
}
getch();
}
