Accompanying CPSC 110 at Mary Washington Class 10. Summer 2012 June 18th, 2012 Assignment due by Thursday. Write a program that produces an animation in a window of at least two ‘bouncing balls’ so that it appears that each shape bounces off the sides of the window and that they also ‘bounce’ off of each other when they collide. Have the balls change color when they bounce off the edges of the window. For up to 10 extra points have them change color and change speed on each bounce. Want more points? Do more balls, more special effects, use mixed shapes – circle, triangle, oval…. Impress me. Discussion problem: Three numbers are given as input and labeled x,y, and z. Write an algorithm to find the maximum of the three. Some review quizzes for Chapters 6, 7 & 8 Posted in assignments , class material | Comments Closed Class 9.

HW for Thursday Modify exercise 2 so that all the circles are appropriately labels with point values as follows: a bull’s eye is worth 9 points and each successive ring is worth 2 points less down to 1 for white. Exercise 11 page 120. When you turn in the HW, send me by email the source for each program and a still or video capture of the output. You can use Jing to capture stills or video from your screen. Jing has free versions for PC and Mac. We will spend a little more time working working with the graphics library. You can use this to get the experience you need to do the HW Before goign to the graphics program we’ll see a brief video presentation Hod Lipson builds “self-aware” robots | Video on TED.com Graphics, another try with more specific instructions Graphics Reference (HTML) Graphics Reference (PDF) Play out a video for the house . Take a look at distance.py for information on how to display information on the screen For lab. Modify triangle.py, http://mcsp.wartburg.edu/zelle/python/ppics2/code/chapter04/triangle.pyw, so that it draws a pentagon rather than a triangle.

See the presentation at https://docs.google.com/present/view?id=ddmmhxsn_1260gr2p29cx Go over chaos program # File: chaos.py # A simple program illustrating chaotic behavior. def main(): print("This program illustrates a chaotic function") x = eval(input("Enter a number between 0 and 1: ")) for i in range(10): x = 3.9 * x * (1 - x) print(x) main() Translation process. Text to Binary In Python the program is interpreted. It is translated to binary by the Python language system and then run. # program to print Hello, World! def main(): print("Hello, World!") main() In Java the program is translated to an intermediate format called bytecodes. These are interpreted or executed by a Java Virtual Machine. In C++ the program is compiled for a specific computer system. #include // class for stream input/output using namespace std; // use the standard namespace int main () //start of main function { // Write 'Hello, World!' to output cout << "Hello, World! " << endl; } Translated to binary or octal (base eight) so it looks like 042577 043114 000401 000001 000000 000000 000000 000000 000002 000003 000001 000000 004630 004005 000064 000000 016500 000000 000000 000000 000064 000040 000005 000050 000036 000035 000006 000000 000064 000000 000064 004005 000000 000000 000240 000000 000240 000000 000005 000000 000000 000000 000003 000000 000324 000000 000000 000000 000000 000000 000021 000000 000000 000000 000004 000000 000000 000000 000001 000000 000000 000000 000000 004005 000000 000000 006764 000000 006764 000000 000005 000000 000000 000001 000001 000000 006764 000000 006764 004006 ...... public class HelloWorld { public static void main( String[] args ) { System.out.println("Hello world"); } } About Writing Programs Writing Programs, Software Development Writing programs to do conversions.
