Create the interface for a Rectangle class with one constructor that accepts two int parameters (width, height),

has one public function area that returns the area of the rectangle, and one private function calculate_area

that calculates area of the rectangle. The class has 3 int private variables area, width, and height.

Create a vector of rectangles

Add 3 Rectangle classes to the vector:

Width Height Area

4 5 20

10 10 100

100 10 1000

Iterate the vector and display the Area for each Rectangle on one line and the total area for the

3 rectangles.
