PREREQUISITE:

Basic knowledge of C language and loops.

ALGORITHM:

1. Take the number of rows as input from the user (height of the inverted pyramid) and store it in a variable ('n').
2. Run a loop 'n' times to iterate through the rows (i=0 to i<n).
3. For each row, print spaces to create the left alignment of the stars.
4. Print stars for each row, which is equal to (2 * (n - i) - 1).
5. Move to the next line after each row has been printed.

Code in C:

#include <stdio.h>

int main() {
    int n, i, j;  // Declaring integers for rows and loop counters
    printf("Enter the number of rows for the inverted pyramid:\n");
    scanf("%d", &n);  // Taking input for number of rows

    for (i = 0; i < n; i++) {
        // Print spaces for inverted pyramid shape
        for (j = 0; j < i; j++) {
            printf(" ");  // Printing spaces
        }
        // Print stars for each row
        for (j = 0; j < (2 * (n - i) - 1); j++) {
            printf("*");  // Printing stars
        }
        printf("\n");  // New line after each row
    }

    return 0;
}
            

Output:

Enter the number of rows for the inverted pyramid:
