C program to print hollow mirrored rhombus star pattern

In this article, I will show you, How to write a C program to print mirrored hollow rhombus star pattern. Here, one thing is important to know that all sides of the rhombus must be the same.

Logic to write C program to print hollow mirrored rhombus star pattern:

It is very easy to print hollow mirrored rhombus star pattern in C, below I have mentioned a few steps to print a hollow mirrored rhombus pattern in C:

You must know the side of the rhombus.
There should be three-loop, two inner and one outer.
First, inner loop print the space x times.
Second, inner loop print star for the first and last row or for the first and last column
After completing each iteration of the inner loops, the outer loop prints the new line.

See the, C program to print hollow mirrored rhombus star pattern:

#include <stdio.h>

int main()
{
    int x = 0,y = 0;
    unsigned int rows = 0;

    printf("Enter the number of rows = ");
    scanf("%u",&rows);

    for(x=1; x<=rows; ++x)
    {
        // Print spaces
        for(y=1; y<= x; ++y)
        {
            printf(" ");
        }
        for(y=1; y<=rows; ++y)
        {
            if((x==1) || (x==rows) || (y==1) || (y==rows))
            {
                //Print star
                printf("*");
            }
            else
            {
                //Print space
                printf(" ");
            }
        }
        // Print new line
        printf("\n");
    }
    return 0;
}

Output:

Code Analysis:

It asks the user to enter the side of the rhombus.

printf("Enter the number of rows = ");
scanf("%u",&rows);

The code contains the three for loop, two inner loop, and one outer loop. The first inner loop prints space x times.

// Print spaces
for(y=1; y<= x; ++y)
{
    printf(" ");
}

The second inner loop print star at first row, column and last row, column using the printf function otherwise print space.

for(y=1; y<=rows; ++y)
{
    if((x==1) || (x==rows) || (y==1) || (y==rows))
    {
        //Print star
        printf("*");
    }
    else
    {
        //Print space
        printf(" ");
    }
}

The outer loop print the newline after each iteration of the inner loops.
