C Program to Print Hollow Inverted Star Pyramid using For Loop

#include<stdio.h>
int main()
{
 	int i, j, rows; 
 	printf("Enter Hollow Inverted Right Triangle Rows =  ");
 	scanf("%d", &rows);
    printf("Hollow Inverted Right Triangle Star Pattern\n");
	for(i = rows; i > 0; i--)
	{
        if(i == 1 || i == rows)
        {
            for(j = 1; j <= i; j++)
            {
                printf("*");
            }
        }
        else
        {
            for(j = 1; j <= i; j++)
            {
                if(j == 1 || j == i)
                {
                    printf("*");
                }
                else
                {
                    printf(" ");
                }
            }
        }   
		printf("\n");
	}
 	return 0;
}

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

C Program to Print Hollow Inverted Star Pyramid using While Loop

#include<stdio.h>
int main()
{
 	int i, j, rows; 
    char ch;
    
    printf("Symbol to Print Hollow Inverted Right Triangle =  ");
    scanf("%c", & ch);
 	printf("Enter Hollow Inverted Right Triangle Rows =  ");
 	scanf("%d", &rows);
    printf("Hollow Inverted Right Triangle Star Pattern\n");
    i = rows;
	while(i > 0)
	{
        if(i == 1 || i == rows)
        {
            j = 1;
            while(j <= i)
            {
                printf("%c", ch);
                j++;
            }
        }
        else
        {
            j = 1;
            while( j <= i)
            {
                if(j == 1 || j == i)
                {
                    printf("%c", ch);
                }
                else
                {
                    printf(" ");
                }
                j++;
            }
        }   
		printf("\n");
        i--;
	}
 	return 0;
}

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