#include <stdio.h>
 
void main()
{
  int rows, i, j;
 
  printf("Enter the no. of rows: ");
  scanf("%d", &rows);
 
  //upper part
  for (i = rows; i >= 0; i--)
  {
    int character = 65;
    for (j = 0; j <= i; j++)
      printf("%c ", (char)(character + j));
 
    printf("\n");
  }
 
  //lower part
  for (i = 0; i <= rows; i++)
  {
    int character = 65;
    for (j = 0; j <= i; j++)
      printf("%c ", (char)(character + j));
 
    printf("\n");
  }
 
  getch();
}

Output:

Enter the no. of rows: 5
A B C D E F
A B C D E
A B C D
A B C

}

Output:

Enter the no. of rows: 5
