/**
 * C program to print right arrow star pattern
 */

#include <stdio.h>

int main()
{
    int i, j, n;

    // Input number of rows from user
    printf("Enter value of n : ");
    scanf("%d", &n);

    // Print the upper part of the arrow
    for(i=1; i<n; i++)
    {
        // Print trailing (2*rownumber-2) spaces
        for(j=1; j<=(2*i-2); j++)
        {
            printf(" ");
        }

        // Print inverted right triangle star pattern
        for(j=i; j<=n; j++)
        {
            printf("*");
        }

        printf("\n");
    }

    // Print lower part of the arrow
    for(i=1; i<=n; i++)
    {
        // Print trailing (2*n - 2*rownumber) spaces
        for(j=1; j<=(2*n - 2*i); j++)
        {
            printf(" ");
        }

        // Print simple right triangle star pattern
        for(j=1; j<=i; j++)

Logic to print right arrow star pattern

This pattern is a combination of two patterns hence, let's first divide it into two parts.

If you have noticed total number of spaces in upper part is 2*rownumber - 2 per row and bottom part contains total 2*n - 2*rownumber spaces per row (where n is the total number of rows). If you ignore leading spaces, then the upper part star pattern is similar to inverted right triangle star pattern and bottom part to simple right triangle star pattern which I already explained how to print.

🎯 How to learn from this example

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.

🔥 Practice suggestion

Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
