Paradigms (1/2)

Imperative- Computation as statements that directly change a program state (e.g. C, C++, Java PHP, Python)

Structured - A style of imperative programming with more logical program structure

Procedural - Derived from structured programming, based on the concept of modular programming or the procedure call

Programming Paradigms (2/2)

Declarative - Defines computation logic without defining its detailed control flow (e.g. SQL, CSS)

Functional- Treats computation as the evaluation of mathematical functions avoiding state and mutable data (e.g. LISP, Scala)

Object-oriented - Treats datafields as objects manipulated through pre-defined methods only (e.g. C++, Java PHP, Python, Ruby, Scala)
