C Program to Print Hollow Mirrored Rhombus Star Pattern

Write a C Program to Print Hollow Mirrored Rhombus Star Pattern using for loop. This C example uses nested for loops and nested if else statements to print the Hollow Mirrored Rhombus Pattern.

#include<stdio.h>
int main()
{
 	int i, j, rows; 
 	printf("Enter Hollow Mirrored Rhombus Rows =  ");
 	scanf("%d", &rows);

    printf("Hollow Mirrored Rhombus Star Pattern\n");
	for(i = 1; i <= rows; i++)
	{
        for(j = i; j > 0; j--)
        {
            printf(" ");
        }

        if(i == 1 || i == rows)
        {
            for(j = 1; j <= rows; j++)
            {
                printf("*");
            }
        }
        else
        {
            for(j = 1; j <= rows; j++)
            {
                if(j == 1 || j == rows)
                {
                    printf("*");
                }
                else
                {
                    printf(" ");
                }
            }
        }   
		printf("\n");
	}
 	return 0;
}

In this C example, we altered the for loops to remove the If else statement to print the Hollow Mirrored Rhombus Star Pattern.

#include<stdio.h>
int main()
{
    int i, j, k, rows;
    printf("Enter Hollow Mirrored Rhombus Star Pattern Rows =  ");
    scanf("%d", &rows);

    printf("Hollow Mirrored Rhombus Star Pattern\n");
    for(i = 1; i <= rows; i++)
    {
        for(j = 1; j < i; j++)
        {
            printf(" ");
        }
        for(k = 1; k <= rows; k++)
        {
            if(i == 1 || i == rows || k == 1 || k == rows)
            {
                printf("*");
            }
            else
            {
                printf(" ");
            }  
        }         
        printf("\n");   
    }
    return 0;
}

Enter Hollow Mirrored Rhombus Star Pattern Rows =  8

This C Program allows entering a symbol to Print as the Hollow Mirrored Rhombus Pattern using while loop.

#include<stdio.h>
int main()
{
    int i, j, k, rows;
    char ch;
    
    printf("Enter Symbol for Hollow Mirrored Rhombus =  ");
    scanf("%c", &ch);
    
    printf("Enter Hollow Mirrored Rhombus Star Pattern Rows =  ");
    scanf("%d", &rows);

    printf("Hollow Mirrored Rhombus Star Pattern\n");
    i = 1;
    while(i <= rows)
    {
        j = 1;
        while(j < i)
        {
            printf(" ");
            j++;
        }
        k = 1;
        while(k <= rows)
        {
            if(i == 1 || i == rows || k == 1 || k == rows)
            {
                printf("%c", ch);
            }
            else
            {
                printf(" ");
            } 
            k++; 
        }         
        printf("\n"); 
        i++;  
    }
    return 0;
}
