Conditionals
Programming basics[1]
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.
The list below is an example of types of conditional questions:
- Match
- Threshold
- Range
- One-of
- Not-match
- Not one of
- All of
- Some of
- Eligible
An example of a simple conditional in PHP can be found below:
A video[edit]
This video references the C programming language and scratch, but the ideas about conditionals are excellent. In the case of conditionals, PHP and C share similar syntax (but not exact).
Standards[edit]
- Define the terms: variable, constant, operator, object.
