C Program to Print Sandglass Alphabets Pattern using For Loop

#include <stdio.h>
int main()
{
	int rows, i, j, k, alphabet;
	printf("Enter Sandglass Pattern of Alphabets Rows = ");
	scanf("%d", &rows);
	printf("The Sandglass Alphabets Pattern\n");
	alphabet = 64;
	for (i = 1; i <= rows; i++)
	{
		for (j = 1; j < i; j++)
		{
			printf(" ");
		}
		for (k = i; k <= rows; k++)
		{
			printf("%c ", alphabet + k);
		}
		printf("\n");
	}
	for (i = rows - 1; i >= 1; i--)
	{
		for (j = 1; j < i; j++)
		{
			printf(" ");
		}
		for (k = i; k <= rows; k++)
		{
			printf("%c ", alphabet + k);
		}
		printf("\n");
	}
}

The result of the above c program; is as follows:

Enter Sandglass Pattern of Alphabets Rows = 5

C Program to Print Sandglass Alphabets Pattern using While Loop

#include <stdio.h>
int main()
{
	int rows, i, j, k, alphabet;
	printf("Enter Sandglass Pattern of Alphabets Rows = ");
	scanf("%d", &rows);
	printf("Printing Sandglass Alphabets Pattern\n");
	alphabet = 64;
	i = 1;
	while (i <= rows)
	{
		j = 1;
		while (j < i)
		{
			printf(" ");
			j++;
		}
		k = i;
		while (k <= rows)
		{
			printf("%c ", alphabet + k);
			k++;
		}
		printf("\n");
		i++;
	}
	i = rows - 1;
	while (i >= 1)
	{
		j = 1;
		while (j < i)
		{
			printf(" ");
			j++;
		}
		k = i;
		while (k <= rows)
		{
			printf("%c ", alphabet + k);
			k++;
		}
		printf("\n");
		i--;
	}
}

The result of the above c program; is as follows:

Enter Sandglass Pattern of Alphabets Rows = 5
