C Program to Print Triangle Pattern of Alphabets using For Loop

#include <stdio.h>

int main()
{
    int i, j, k, rows, alphabet;
    
    printf("Enter Triangle Alphabets Pattern Rows = ");
    scanf("%d",&rows);

    printf("\nThe Triangle Alphabets Pattern\n"); 
    
	for (i = 0 ; i < rows; i++ ) 
	{
		alphabet = 65;
		for (j = rows ; j > i; j-- ) 	
		{
			printf(" ");
		}
		for(k = 0; k <= i; k++)
		{
			printf("%c ", alphabet + k);
		}
		printf("\n");
