C Program to Print Square of Right Decrement Numbers Pattern

Write a C program to print square of right decrement numbers pattern using for loop.

#include <stdio.h>

int main()
{
	int rows;

	printf("Enter Square Right Decrement Numbers Rows = ");
	scanf("%d", &rows);

	printf("The Square of Right Decrement Numbers Pattern\n");

	for (int i = rows; i >= 1; i--)
	{
		for (int j = rows; j >= i; j--)
		{
			printf("%d ", j);
		}
		for (int k = rows - i + 1; k < rows; k++)
		{
			printf("%d ", i);
		}
		printf("\n");
	}
}

This C program prints the square pattern of right decremented numbers using a while loop.

#include <stdio.h>

int main()
{
	int rows, i, j, k;

	printf("Enter Square Right Decrement Numbers Rows = ");
	scanf("%d", &rows);

	printf("The Square of Right Decrement Numbers Pattern\n");
	i = rows;

	while (i >= 1)
	{
		j = rows;
		while (j >= i)
		{
			printf("%d ", j);
			j--;
		}
		k = rows - i + 1;
		while (k < rows)
		{
			printf("%d ", i);
			k++;
		}
		printf("\n");
		i--;
	}
}
