The document discusses object-oriented programming (OOP) languages and provides examples to illustrate key concepts. It defines an object as something that can have features and behaviors. Features represent variables, while behaviors represent methods. A car object is used as an example, with features like speed and gear, and behaviors like changing gears and braking. The main features of OOP are identified as objects, classes, inheritance, abstraction, interfaces, encapsulation, polymorphism, and data abstraction. C++ is presented as an example of an OOP language that supports both procedural and object-oriented programming.
