Lesson Details
Key learning points
- In a project with multiple sprites, it is useful to assign them meaningful names.
- An algorithm is a defined sequence that can be followed and represented in code.
- An error in code is often called a bug.
- Errors can be found and corrected through debugging.
Common misconception
An algorithm cannot be represented in code.
An algorithm is a description of the instructions to follow so that a specified task can be completed. Therefore, algorithms can be converted and represented in to program code to enable a computer to carry out the solution to a task.
