What does the following program do?
import turtle
def main():
turtle. hideturtle()
square(100,0,50,'blue')
def square(x, y, width, color):
turtle. penup()
turtle. goto(x, y)
turtle. fillcolor(color)
turtle. pendown()
turtle. begin_fill()
for count in range(2):
turtle. forward(width)
turtle. left(90)
turtle. end_fill()
main()
it draws 2 blue lines.
a) it draws a blue square at coordinates (100, 0), 50 pixels wide, starting at the top right. b) it draws a blue square at coordinates (0, 50), 100 pixels wide, starting at the top right. c) it draws a blue square at coordinates (100, 0), 50 pixels wide, in the lower-left corner. d) nothing since you cannot call a function with turtle graphics corner

C

Explanation:

It draws the blue square at coordinates (100,0) 50 pixel wide, and in the lower-left corner. You should know that the lower-left corner of the square should be at position x, y. Hence, the answer.

And this is true for any shape that you draw using turtle graphics in Python.

You should also know the function format of python, and how it is defined, declared and called. The penup command tells the turtle to not show what is drawn, or hide the ink. The pen down is just opposite to this.

The count is an inbuilt function that counts and can be used as above with range to create a for the look. forward moves the cursor according to width mentioned.

See how to pen down is called before beginning fill. And how we move to x,y using go to, and how the penup is used to hide ink while fill color is in effect, and we move to x,y.

End fill ends the process.

it really depends on where you stay, because   i stay it houston texas a very good college for me to go to with a 2.5 grade point average would be uofh university of houston

if can plz mark brainliest

that without the operating systems you would have to control and synchronize computer hardware.
