Write a C++ Program to display the pattern like pyramid using the alphabet.

#include <iostream>
using namespace std;
void main()
{
      int i, j;
   char alph = 'A';
   int n,blk;
   int ctr = 1;

   cout<<"Input the number of Letters (less than 26) in the Pyramid : ";
   cin>>n;
 Write a C Program to display the pattern like pyramid using the alphabet.
   for (i = 1; i <= n; i++)
{
for(blk=1;blk<=n-i;blk++)
     
cout<<"  ";
      for (j = 0; j <= (ctr / 2); j++) {
         cout<<" "<< alph++;
      }

      alph = alph - 2;

      for (j = 0; j < (ctr / 2); j++) {
         cout<<" "<< alph--;
      }
      ctr = ctr + 2;
      alph = 'A';
      cout<<endl;
   }

      system ("pause");
}

Output:

          A

      A B A 

    A B C B A

  A B C D C B A
