Print reverse floyd's triangle

Here given code implementation process.

//C Program

#include <stdio.h>

//Print floyd triangle of given rows
void floyd_triangle(int row)
{
	printf("ROW SIZE : %d\n\n", row);
	//declare loop control variable
	int i = 0;
	int j = 0;
	//counter variable is used to display triangle values
	int counter = (row * (row + 1)) / 2;
	for (i = 0; i < row; ++i)
	{
