OOPS concepts in C++ include encapsulation, inheritance, polymorphism, and abstraction.

• Encapsulation: Bundling data and methods that operate on the data into a single unit (class). Example: class Car { private: int speed; public: void accelerate() { speed++; } };

• Inheritance: Creating new classes based on existing classes. Example: class ElectricCar : public Car { public: void charge() { cout << 'Charging...'; } };

• Polymorphism: Ability to present the same interface for differe...read more
