Answer Key
VCE Software Development U4O1 · Modules 82–114 · Student wording will vary for definitions
1access modifier — Marks a class member as public (name), protected (_name) or private (__name), so the class exposes only what other code needs.
2readable code — Code that people can quickly understand, using clear names, consistent indentation and spacing, short functions with no repeated code, and helpful comments.
3sum(), min(), max() — Built-in functions that return the total, smallest and largest value in a list, replacing a hand-written loop with one short, clear line of code.
4[x for x in items] — A list comprehension builds a new list from a loop in one expression. Add 'if condition' to filter items, or change x (e.g. x * 2) to transform each item.
5refactoring — Rewriting working code to make it clearer or simpler (e.g. renaming variables, moving repeated lines into a function) without changing what it does, then re-running tests.
6maintainable code — Code organised so it can be fixed or extended later without breaking other parts, using small functions, classes that hide detail and constants instead of repeated values.
7header comment — A comment at the top of a file that records the program's purpose, author, date and any changes made, so others can understand and maintain the code.
8repository — A storage location for a project's files and full change history. It can be local or remote (e.g. GitHub), lets a team share code, and keeps a backup of every version.
9git commit -m "message" — Records a snapshot of the files you staged with git add, saving it in the repository history with a short message that explains what changed.
10git clone, git push, git pull — clone copies a remote repository to your computer; push uploads your commits to the remote; pull downloads other people's new changes into your copy.
