C Program to Print Square of Left Decrement Numbers Pattern using For Loop

#include <stdio.h>
int main()
{
	int rows;
	printf("Enter Square of Left Dec Numbers Rows = ");
	scanf("%d", &rows);
	printf("Square of Decrement Numbers from Left Side\n");
	for (int i = rows; i >= 1; i--)
	{
		for (int j = i; j < rows; j++)
		{
			printf("%d ", j);
		}
		for (int k = rows - i; k < rows; k++)
		{
			printf("%d ", rows);
		}
		printf("\n");
	}
}

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

Enter Square of Left Dec Numbers Rows = 5
Square of Decrement Numbers from Left Side
5 5 5 5 5 
4 5 5 5 5 
3 4 5 5 5 
2 3 4 5 5 
1 2 3 4 5 

C Program to Print Square of Left Decrement Numbers Pattern using While Loop

#include <stdio.h>
int main()
{
	int rows, i, j, k;
	printf("Enter Square of Left Dec Numbers Rows = ");
	scanf("%d", &rows);
	printf("Square of Decrement Numbers from Left Side\n");
	i = rows;
	while (i >= 1)
	{
		j = i;
		while (j < rows)
		{
			printf("%d ", j);
			j++;
		}
		k = rows - i;
		while (k < rows)
		{
			printf("%d ", rows);
			k++;
		}
		printf("\n");
		i--;
	}
}

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