2. Learning Targets
Demonstrate your awesome ability to use the random command
Be able to create a wonderful piece of Pascal art using graphic commands
Prepare for a quiz on Friday by successfully completing a practice quiz.

3. Solve the Following Random(12)+3 Random(14) – 8 Random(10)+ 20
Find the range of values
Write the code to generate the following ranges of random numbers
Random(12)+3
Random(14) – 8
Random(10)+ 20
2*random(6)+5
2*random(10) – 3
5*random(12) - 6
5 to 15
-8 to 30
40 to 100 even
37 to 57 odd
5 to 50 every 5th

4. Some Pascal Graphics Commands
Some Commands
SetColor(Integervariable);
Circle(x, y, radius);
ClearViewPort; //Like clearscreen
Outtext(x, y, ‘String you will show on the screen’);
Line(x1, y1, x2, y2);
Lineto(x,y);
Putpixel(x, y, ColorValue);
Rectangle(x1, y1, x2, y2);
Ellipse(x, y, Start Degrees, End Degrees, Horizontal Radius, Vertical Radius);
Colorvariable:=getpixel(x, y);

5. Today First graphics program Inside circle program:
Face
Stick figure
House
Inside circle program:
Input: The (x,y) coordinate and center of a circle. Also the (x2,y2) coordinates of another point
Output: Whether or not the point is inside the circle. (Hint: Use the distance formula)
Push: In addition, show this graphically
Intersecting circles program:
Input: x, y and radius for two circles.
Output whether or not the circles intersect.
Push: Add graphics
