C Program to Print Right Pascals Triangle Alphabets Pattern using For Loop

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

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