    Inheritance is used for an IS-A relationship.
    Aggregation is used for a HAS-A relationship.

    Cars, Scooters are vehicles. (Inheritance)

    Car has a steering, wheel etc. (Aggregation)

    In Inheritance, a class inherits the properties of the base class.
    In Aggregation, a class uses the properties of some other class.

    Inheritance is the process where one object acquires the feature of another
    object. It depicts is-a relationship. Like car is-a vehicle.

    Aggregation deals with Has-a relationship. For example car has engine..
    here engine is an object which is a part of another object called car.
