What is Programming Paradigms?
Within Computer Science, which covers algorithms, programming, data, networks, hardware and safe, responsible use of technology, this topic explains Programming Paradigms. Computing topics explain how software, hardware and data work, with diagrams and models that show each step in order.
Check that you can explain Programming Paradigms in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Programming Paradigms helps you design, test and explain programs, websites and systems, from small projects to exam questions.
Programming Paradigms in detail
A programming paradigm is a style or approach to programming. Procedural programming organises code as a sequence of instructions grouped into procedures and functions, as in C and Python scripts. Object-oriented programming models the world as objects with data and methods, as in Java.
Functional programming treats computation as evaluating functions without changing state (Haskell), and declarative programming states what is wanted rather than how (SQL). Many languages support several styles. Choosing a paradigm depends on the problem: events suit GUIs, and objects suit large simulations.
How the interactive helps you understand Programming Paradigms
Click a card to flip it and reveal the answer, then move on to the next one.
Before you change anything, predict the result. Then change one value at a time and check whether your prediction was right. This is a quick way to build a correct mental model of Programming Paradigms.
Real-life uses and examples
- Apply Programming Paradigms when you design a small program, website or spreadsheet.
- Explain Programming Paradigms to someone new to computing by comparing it to a familiar process.
- Trace through a process that uses Programming Paradigms to check what it does step by step.
Common mistakes to avoid
- Testing only the normal case and forgetting the edge cases.
- Using the term without being able to say what the computer actually does.
- Learning the definition without testing it. Use the quiz and the interactive to check that you can apply the idea.
