The source identifies two primary ways to control the number of iterations within a while loop:

1. Coordinate-Based Conditions:
   • The loop continues based on a spatial limit (e.g., drawing circles until the X-coordinate reaches a certain pixel value).
   • Example: If the increment is small (e.g., 1 pixel), the objects may appear as a solid trail; larger increments create distinct, separated objects.
2. Counter-Based Conditions:
   • A specific "count" variable is used to dictate the exact number of objects to be drawn.
   • Process: Initialize count = 0, set the condition (e.g., count < 10), and increment the count within the curly brackets (count++ or count += 1). This ensures the loop runs exactly for the specified number of iterations.
