C Program to Print Right Triangle Characters Pattern using For Loop

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

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

Enter Right Triangle of Characters Rows = 5

	printf("Right Angled Triangle of Characters Pattern\n");
	alphabet = 65;
	i = 1;
	while (i <= rows)
	{
		j = 0;
		while (j <= (2 * i - 2))
		{
			printf("%c ", alphabet + j);
			j++;
		}
		printf("\n");
		i++;
	}
}
