PART 1

do it in c++

A. Factory design method

Make a base class shapes and derived class circle, rectangle, square

Implement the factory design pattern for this question.

B. Abstract class/Pure virtual function

Car:: before drive, car should be test properly

Create a base class Car thar have virtual function engine, breaks, tyre now

class Car{

public:

virtual void engine ()=0;

virtual void breaks ()=0;

virtual void tyre ()=0;

};

bool testingCar(Car *a){

a->engine();//polymorphic call

a->breaks ();

a->tyre();

return true;

}
