output: 
logic) Vehicle class is a base class, and types of vehicle such as diesel car, electric car are inheritance class. initialize constructor in base class vehicle class. and create a function to add , remove and update vehicle list etc. from base class. In main function initialize an object electriccar of derived class ElectricCar and take the input as an index of which function to be called and get the output.
