{  
    public static void Main() 
  {
   int i, j;
   char alph = 'A';
   int n;
   int ctr = 1;
  
	Console.Write("\n\n");
    Console.Write("Display the pattern like pyramid using the alphabet:\n");
    Console.Write("------------------------------------------------------");
    Console.Write("\n\n");     
 
   Console.Write("Input the number of Letters (less than 26) in the Pyramid : \n");
   n = Convert.ToInt32(Console.ReadLine());    
 
   for (i = 1; i <= n; i++) {
      for (j = 0; j <= (ctr / 2); j++) 
	  {
         Console.Write("{0} ", alph++);
      }
      alph--;
      alph--;
 
      for (j = 0; j < (ctr / 2); j++) {
         Console.Write("{0} ", alph--);
      }
      ctr = ctr + 2;
      alph = 'A';
      Console.Write("\n");
   }
  } 
}

Sample Output:

Display the pattern like pyramid using the alphabet:
