A conditional statement evaluates an expression and executes instructions depending on the outcome of the evaluation. Conditionals depend on operators to evaluate if an expression is true or false. A condition and selection are not the same thing. A condition asks a question. A selection processes the answer.
With gratitude to and permission from Stephen Hughes (Coe College) and Philip East (University of Northern Iowa)[2], The list below is an example of types of conditional questions. You should start thinking about conditions in plain english before you start thinking about operators.
- Match
- Threshold
- Range
- One-of
- Not-match
- Not one of
- All of
- Some of
- Eligible
A video[edit]
This video references the C programming language and scratch, but the ideas about conditionals are excellent.
