What are some examples of C++ concepts?

C++ has several key concepts like classes, inheritance, polymorphism, and templates. Would you like examples of each?

Yes, please provide an example of classes.

Sure! A class in C++ can be defined as follows:

class Car {
public:
    string brand;
    string model;
    int year;

    void displayInfo() {
        cout << brand << " " << model << " " << year;
    }
};

This defines a Car class with attributes and a method.

What about inheritance?

Inheritance allows a class to inherit properties and methods from another class. For example:

class Vehicle {
public:
    void start() {
        cout << "Vehicle started";
    }
};

class Car : public Vehicle {
public:
    void honk() {
        cout << "Car honking";
    }
};

Here, Car inherits from Vehicle.

Can you explain polymorphism?

Polymorphism allows methods to do different things based on the object that it is acting upon. For example:

class Animal {
public:
    virtual void sound() {
        cout << "Animal sound";
    }
};

class Dog : public Animal {
public:
    void sound() override {
        cout << "Bark";
    }
};

In this case, Dog overrides the sound method.
