Q2. Modify Q1 so draw( )is a pure virtual function. Try creating an object of type Shape. Try to call the pure virtual function inside the constructor and see what happens. Leaving it as a pure virtual, give draw( ) a definition.

here is Q1

#include

using namespace std;

class Shape{ public: virtual void draw(){ cout<<"Drawing Shape "; } }; class Circle : public Shape{ void draw(){ cout<<"Drawing Circle "; } }; class Square : public Shape{ void draw(){ cout<<"Drawing Square "; } };

class Triangle :public Shape{ void draw(){ cout<<"Drawing Triangle "; } }; int main() { // creating pointers for base class Shape *s[5]; s[0] = new Shape(); // creating objects for child class Circle *c = new Circle(); Square * sq = new Square(); Triangle * t = new Triangle(); // peforming upcasting s[1] = c; s[2] = sq; s[3] = t; // calling draw s[1]->draw(); s[2]->draw(); s[3]->draw();

return 0; }
