Explanation of the Code
Header Files: The program includes stdio.h to use standard input and output functions.
Getting User Input:
We declare an integer variable rows to store the number of rows for the inverted pyramid.
We prompt the user to enter the desired number of rows.
Outer Loop:
The outer loop (for (int i = 0; i < rows; i++)) runs once for each row of the inverted pyramid.
Inner Loop for Spaces:
The first inner loop (for (int j = 0; j < i; j++)) prints spaces to create the indentation. The number of spaces increases as we move down the rows.
Inner Loop for Stars:
The second inner loop (for (int k = 0; k < (2 * (rows - i) - 1); k++)) prints the stars. The number of stars decreases as we go down each row, calculated by 2×(rows−i)−12 \times (\text{rows} – i) – 12×(rows−i)−1.
New Line:
After printing the stars for each row, we use printf("\n") to move to the next line.
Output:
Enter the number of rows: 5
