Predicting code output
1. Function parameters
don't have to be numbers
2. Abstraction
a simplified representation of something more complex; allows you to hide details to help you manage complexity
Functions are a form of abstraction
3. Top-down Design
relies upon identifying sub-problems of a larger problem
also known as decomposition
4. Pseudocode
Max (a, b)
is a made up function that returns the greater of TWO values.
How would you use this function to find the greatest of THREE values?
Max (Max (a, b), c)
5. Debugging
The program doesn't know what size is, because it hasn't been defined as part of a function.
We can turn this into a function with a size parameter, OR
replace size with actual numbers
6. Iterative change
An iterative change (process) is based on figuring out how to make the code better, have more functionality, or be more organized. It doesn't change the overall design of a program.
- Writing a sequence of commands to draw a fish, and then turning it into a function (more functionality)
- Finding a better way to draw a fish (make the code better)
- Moving function calls to the top (be more organized)
- Removing unnecessary code
