Programming Language Paradigms - XML

Programming language paradigms are fundamental styles or approaches that define the structure and execution of programs. Major paradigms include imperative, declarative, object-oriented, and functional, each offering different approaches to problem-solving. Many modern languages are designed as multi-paradigm languages, combining multiple paradigms to allow developers to choose the most suitable approach for their problems.
