  • Let's see the C# example to print number triangle.

Example1:

using System;  
  	public class PrintExample  
   {  
     public static void Main(string[] args)  
      {  
       int i,j,k,l,n;           
       Console.Write("Enter the Range=");    
       n= int.Parse(Console.ReadLine());     
       for(i=1; i<=n; i++)      
       {          
        for(j=1; j<=n-i; j++)      
        {      
         Console.Write(" ");      
        }      
        for(k=1;k<=i;k++)      
        {      
         Console.Write(k);      
        }      
        for(l=i-1;l>=1;l--)      
        {      
        Console.Write(l);      
        }      
        Console.Write("\n");      
       }       
   }  
  } 

C# examples - Output :

Enter the Range=5
     1
    121
   12321
  1234321
 123454321  
Enter the Range=6
      1
     121
    12321
   1234321 
  123454321
 12345654321

Example2:

using System;
class Pascal
{
    public static void Main()
    {
        int[,] arr = new int[8, 8];     
        for (int i = 0; i < 8; i++)
        {
            for (int k = 7; k > i; k--)
            {   //For loop to print spaces
                Console.Write(" ");
            }
 
            for (int j = 0; j < i; j++)
            {
                if (j == 0 || i == j)
                {
                    arr[i, j] = 1;
                }
                else
                {
                    arr[i, j] = arr[i - 1, j] + arr[i - 1, j - 1];
                }
                Console.Write(arr[i, j] + " ");
            }
            Console.WriteLine();
 
        }
        Console.ReadLine();
    }
}
