It takes one parameter i, which will represent the number of rows in our triangle. This will form one row of the triangle. This step is important because it helps us move towards the apex of the triangle, reducing the number of stars in each row. In summary, this code defines a stored procedure that draws a triangular pattern of stars by looping through rows and decreasing the number of stars in each subsequent row until reaching the apex of the triangle. You can call this procedure with different values of i to draw triangles of varying heights. Your email address will not be published.
