Hello! I'm Chris and I looked at Phrogram as an easy way to introduce coding for educational purposes. I'm a physicist and mathematician and earn a crust providing mathematical and physical modelling services. Over the last 5 years I've started doing more outreach type activities to promote maths (all aspects - for physical to ...

This program won second runner-up in Phrogram's Winter/Spring 2008 programming contest. It's a fun little game that takes easy math and makes it as fun and exciting as, well chasing butterflies on a beautiful spring day! For more info, see this thread.

This program was first runner up in Phrogram's 2008 Spring/WInter programming contest, for best use of math in a program. It's a fascinating display of shadow effects on math-created objects in a 2D environment. For more info, see this thread.

This program is the winner of Phrogram's 2008 Winter/Spring programming contest, for best use of math in a program. It's a well commented, conceived and fun to use program that takes what might be a random polygon and gives it a precise measurement using a single line length determinant. For more info, see this thread.

This is another variation on the CountFour programs and shows how you can create a function that derives an average. In this program, the user is prompted to enter a series of numbers of his or her own choosing. The program also adds up all the inputs (both their number , or "count" and their values) and writes the information to the ...

I went ahead and moved this thread to Beginner's Corner. Thanks for the pointer, Srjek. Of course, it is possible to get an average without having a built-in average method. A while ago, I was playing around with a program called CountFour and got some help from ZMan and LFS to improve my very rudimentary first stab on how to count up 4 ...

Author: Ken Ingle Ken's comments about the program: The PolarCoordinates program shows off some simple but interesting graphs plotted within a polar coordinate system. The polar coordinates are converted to (X,Y) cartesian coordinates for screen display. The CartesianPoint structure is used to pass (X, Y) coordinates when doing the ...

In this program, the user is prompted to enter four numbers in the console. The program then totals all the positive and negative numbers separately and counts how many positive numbers, negative numbers and zeros were entered. This program shows how a simple helper function can eliminate repetitive code by maintaining totals and counts of ...

This program is a little illustration of some things you can do manipulating numbers arithmetically in a console program. It was inspired by an end-of-chapter 3 exercise in "Visual Basic 2005, How to Program" by Deitel: "Write a program that inputs five numbers and determines and prints the number of negative numbers input, the ...

Per Michael's post (July 13) - This is a little program witch combinates recursion,turtle graphic and geometrie. Uncomment line 23 to see slowly how it works. Per Michael - on LFS version, uncomment line 40 to run more slowly
