For the given code create symbol table: .................................................................................... class Polygon { protected: int width, height; public: Polygon (int a, int b) : width(a), height(b) {} virtual int area (void) =0; void printarea() { cout << this->area() << ' '; } }; class Rectangle: public Polygon { public: Rectangle(int a,int b) : Polygon(a,b) {} int area() { return width*height; } };

class Triangle: public Polygon { public: Triangle(int a,int b) : Polygon(a,b) {} int area() { return width*height/2; } };

int main () { Polygon * ppoly1 = new Rectangle (4,5); Polygon * ppoly2 = new Triangle (4,5); ppoly1->printarea(); ppoly2->printarea(); delete ppoly1; delete ppoly2; return 0; }
