Quick explanation
Boolean operations in a programming language: Be familiar with and be able to use: • NOT • AND • OR • XOR
- This point belongs to Programming, especially Boolean operations in a programming language.
- You need to be able to boolean operations in a programming language: Be familiar with and be able to use: • NOT • AND • OR • XOR.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Why it matters
This objective helps connect Boolean operations in a programming language to exam-style questions, flashcards, and revision notes for Programming.
Quick student answer
In Python 3, what is the result of `not False`?
Direct answer
True
Key terms
- Boolean operation: An operation that works with Boolean values, usually True or False, to produce a Boolean result.
- XOR: Exclusive OR; a Boolean operation that produces True when exactly one input is True.
Common trap
Confusing OR with XOR: OR is True when at least one input is True, including when both inputs are True. XOR is True only when exactly one input is True.

- Data types: Understand the concept of a data type. Understand and use the following appropriately: • integer • real/float • Boolean • character • string • date/time • pointer/reference • records (or equivalent) • arrays (or equivalent). Variables declared as a pointer or reference data type are used as stores for memory addresses of objects created at runtime, ie dynamically. Not all languages support explicit pointer types, but students should have an opportunity to understand this data type. Define and use user-defined data types based on language-defined (built-in) data types.
Data types
- Programming concepts: Use, understand and know how the following statement types can be combined in programs: • variable declaration • constant declaration • assignment • iteration • selection • subroutine (procedure/function). The three combining principles (sequence, iteration/repetition and selection/choice) are basic to all imperative programming languages. Use definite and indefinite iteration, including indefinite iteration with the condition(s) at the start or the end of the iterative structure. A theoretical understanding of condition(s) at either end of an iterative structure is required, regardless of whether they are supported by the language being used. Use nested selection and nested iteration structures. Use meaningful identifier names and know why it is important to use them.
