Like the alphabet triangle, we can write the C# program to print the number triangle. The number triangle can be printed in different ways.

Let us see the C# example to print the number triangle.

💻 Program Code

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");      
       }       
   }  
  }

🖥 Program Output

Enter the Range=5
     1
    121
   12321
  1234321
 123454321

🎯 How to learn from this example

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.

🔥 Practice suggestion

Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
