Flashcards

Object-Oriented Programming (OOP)

A programming paradigm that organizes software design around objects, which combine data and functions.

C++'s Relation to C

C++ was designed to be compatible with C, allowing existing C code to be used in C++ programs.

C++ and Object-Oriented features

Despite its compatibility with C, C++ offers object-oriented programming features that C lacks.

OO Programming Importance

Learning fundamental OOP concepts before diving into a specific programming language is crucial for understanding and using object-oriented environments effectively.
