7. Components of Pseudo-Code
Sequence = Do the highest line first, then perform them in order from top to bottom
Line = one “thing” to do
Repetition = repeat something
Fixed number of times : e.g. “repeat 3 times”
Until something happens: e.g. “until hair is foamy”
Conditions/Decisions = maybe do something
Check something first
If there is no more shampoo, then get more
Named actions = two parts: definition, use
Definition = how to do a thing
Use = when to do the thing defined

8. Bugs Syntax Semantic Logical Understandability
Statement does not “parse”
Semantic
Grammatically correct, but nonsense
Logical
Means something, but not what you meant
Understandability
I said it, it makes sense, and it means what I meant, but no one else can understand it
