Program Maintainability Flashcards

All 5 cards in this deck

What is maintainability in defensive design?: Ensuring a program can be understood and changed by other programmers, e.g. by using modularisation and comments.
How does using sub programs help maintainability?: It splits the program into smaller named sections that can be reused, read, tested and updated separately.
How do naming conventions (sensible identifier names) help maintainability?: Meaningful variable and sub program names show what each one stores or does, so the code is easier to follow, e.g. totalScore rather than x.
How does indentation help maintainability?: It shows which lines are inside a loop, condition or sub program, making the structure of the code clear.
What is a comment in a program, and why is it useful?: A note in the code that is ignored by the translator; it explains what a section of code does so others can understand it.
