Control Structures

Logic flow control mechanisms present in all languages:

  • Conditionals: if/else statements for decision making
  • Loops: for, while loops for repetitive tasks
  • Functions: Reusable code blocks
  • Classes: Object-oriented programming structures

Programming Paradigms

Different approaches to structuring code:

  • Procedural: Step-by-step instructions (C, Pascal)
  • Object-Oriented: Code organized around objects (Java, C#)
  • Functional: Functions as first-class citizens (Haskell, Lisp)
  • Declarative: Describing what to achieve (SQL, HTML)

Tips for Learning Programming Languages Effectively
