What is maintainable/extensible code?

` Can it be taught?

` Clichés are true; the trick is to know when to bend the

rules!

Why do we write un-maintainable

code?

` Laziness

` Use all the tools in the box

` Inexperience ~ haven’t extended a programp p g

` Indifference ~ Elitism

` My method is the best

` Others should not be able to understand!

Why should we write maintainable

code?

` Clear code almost always results in reliable code

(functionality & security)

` “…except for very rare instances, the lifetime cost

of code written to be maintainable from the start will

always be less than the cost of code written with little

or no thought to maintainability”

Documentation

` Too little - too much

` Useful comments

` Keep your comments short

`` Spell checkSpell check

` How serious one is about comments

` If there are questions about the code, comments

need to be improved

Code formatting

` Use consistent formatting

` Tabs vs Spaces

Always use spaces Set your IDE to replace TABS with spacesy

` Follow the convention

Remember!!!

Any violation of the convention is allowed if

it enhances readabilityy
