C

#include <stdio.h>

int main()
{
  int n = 9, x = 1;
  int i,j;

  for(i = 1; i <= n; i++)
  {
    for (j = 1; j <= x; j++)
    {
      printf("%2d ", j);
    }
    if (i <= n / 2)
      x++;
    else
      x--;
    printf("\n");
  }
  return 0;
}

C++

#include <iostream.h>

int main()
{
  int n = 9, x = 1;
  
  for(int i = 1; i <= n; i++)
  {
    for(int j = 1; j <= x; j++)
    {
      cout<<j<<" ";
    }
    if (i <= n / 2)
      x++;
    else
      x--;
    cout<<endl;
  }
  return 0;
}

Java

class PatternProg
{
	public static void main(String args[])
	{
	  int n = 9;
	  int x = 1;

	  for (int i = 1; i <= n; i++)
	  {
		for (int j = 1; j <= x; j++)
		{
		  System.out.print(j+" ");
		}
		if (i <= n / 2)
		{
		  x++;
		}
		else
		{
		  x--;
		}
		System.out.println();
	  }
	  
	}
}

C#

using System;

class PatternProg
{
  public static void Main()
  {
    int n = 9;
    int x = 1;

    for (int i = 1; i <= n; i++)
    {
      for (int j = 1; j <= x; j++)
      {
        Console.Write(j + " ");
      }
      if (i <= n / 2)
      {
        x++;
      }
      else
      {
        x--;
      }
      Console.WriteLine();
    }

    Console.ReadKey(true);
  }
}

Python

n = 9
d = 1

for x in range(1, n + 1):
  for y in range(1, d + 1):
    print(y, end=" ")

  if x <= n // 2:
     d += 1
  else:
     d -= 1
  print()
