Please remember our 05-04 Lab Exercise 3: Write class shape with width and height

How to use Abstract class to solve the problem?

Write class shape with width and height following a constructor that gives value to them.

Then define two sub-classes triangle and rectangle.

Those sub-classes can calculate the area of the shape area().

Remember, Rectangle area = (width * height)

Triangle area = (width * height)/2

``````#include <iostream>
using namespace std;
// Base class
class Shape
{
public:
// Your code: pure virtual function providing interface framework.
// constructor and setWidth(int w) and setHeight(int h) functions here
protected:
int width;
int height;
};
// Derived classes
class Rectangle: public Shape
{
public:
// Your code:    int getArea()
};
class Triangle: public Shape
{
public:
// Your code:    int getArea()
};
int main(void)
{
Rectangle Rect;
Triangle  Tri;
int w,h;
cin >>w>>h;
Rect.setWidth(w);
Rect.setHeight(h);
cin >>w>>h;
Tri.setWidth(w);
Tri.setHeight(h);
cout << Rect.getArea() << ";" << Tri.getArea() << endl;
return 0;
}``````
