In this tutorial, we will write a C program to print an hourglass pattern using characters. Before that, you may go through the following topic in C.

Full hourglass pattern of Alphabets in C

#include <stdio.h>

void main()
{
  int rows, i, j, k;

  printf("Enter the no. of rows: ");
  scanf("%d", &rows);

  // ASCII value of alphabet 'A'
  int alphabet = 65;

  for (i = 0; i <= rows - 1; i++)
  {
    for (j = 0; j < i; j++)
      printf(" ");

    for (k = i; k <= rows - 1; k++)
      printf("%c ", (char)(alphabet + k));

    printf("\n");
  }

  for (i = rows - 1; i >= 0; i--)
  {
    for (j = 0; j < i; j++)
      printf(" ");

    for (k = i; k <= rows - 1; k++)
      printf("%c ", (char)(alphabet + k));

    printf("\n");
  }

  getch();
}

Output:

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

D E
C D E
B C D E
A B C D E
