Question

SetTimer(draw, 20);

When will the function draw be called?
a) Every 20 milliseconds
b) After 20 seconds
c) On a mouse click
d) When the timer is manually triggered

Answer 1

The draw function will be called every 20 milliseconds using setTimer(draw, 20). It is not dependent on a mouse click or manual trigger, and the delay specified is in milliseconds, not seconds.

Step-by-step explanation:

The function draw will be called every 20 milliseconds. This is because the setTimer function in programming typically takes two parameters: the first is the function to be executed and the second is the delay in milliseconds. So, when you see setTimer(draw, 20), that means the draw function will trigger every 20 milliseconds, not after 20 seconds, not on a mouse click, or when the timer is manually triggered.For example, if you use DISM to install a new driver into a Windows image, the change is saved instantly after the command is executed without any additional save command. This behavior emphasizes the importance of command accuracy and understanding the implications of each modification you make to an image.
