Bitmap vs. Vector Based Graphics
It’s almost impossible to discuss graphics software without first establishing an understanding of the differences between the two major graphic types: bitmap and vector images. The following “fill in the blank” activities will test your understanding of the characteristics of…
Data Validation Quiz
When programming a computer system, it is good practice to include a range of validation checks in the code to check if the data being inputted by the end-user follows some basic rules. The aim of validation checks is to…
Vera Molnár’s Artwork revisited using Python
Vera Molnár (born 1924) is a French media artist of Hungarian origin. She is considered to be a pioneer of computer art. Trained as a traditional artist, she began working with computers in 1968, where she began to create algorithmic…
Triangle Geometry Functions
In this challenge we will create a library of functions to apply the different formulas based on the geometry of triangles. For each function, you will need to design the algorithm using either Pseudo-code or a flowchart, implement the function…
Heron’s Formula
The Heron’s formula is a famous formula used to calculate the area of a triangle based on the length of its three sides. It is called “Heron’s Formula” (sometimes called Hero’s formula) after Hero of Alexandria who was a Greek…
Linear Search Functions
For this programming challenge we will investigate different functions which will all be based on a linear search algorithm. Let’s consider a teacher who has decided to keep track of rewards issued to their students throughout the term by adding…
