C Program to Print Right Arrow Alphabets Pattern using For Loop

#include <stdio.h>
int main()
{
	int rows, i, j, k, alphabet;
	printf("Enter Right Arrow Pattern of Alphabets Rows = ");
	scanf("%d", &rows);
	printf("Printing Right Arrow Alphabets Pattern\n");
	alphabet = 65;
	for (i = 0; i < rows; i++)
	{
		for (j = 0; j < i; j++)
		{
			printf(" ");
		}
		for (k = i; k < rows; k++)
		{
			printf("%c", alphabet + k);
		}
		printf("\n");
	}
	for (i = rows - 2; i >= 0; i--)
	{
		for (j = 0; j < i; j++)
		{
			printf(" ");
		}
		for (k = i; k <= rows - 1; k++)
		{
			printf("%c", alphabet + k);
		}
		printf("\n");
	}
}

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