Question
A super class Perimeter has been defined to calculate the perimeter of a parallelogram. Define a subclass Area to compute the area of the parallelogram by using the required data members of the super class. The details are given below:
Classname:Perimeter
Data members / instance variables:
a:to store the length in decimal
b:to store the breadth in decimal
Member functions:
Perimeter(…):parameterized constructor to assign values to data members
double Calculate():calculate and return the perimeter of a parallelogram as 2*(length+breadth)
void show():to display the data members along with the perimeter of the parallelogram
Classname:Area
Data members / instance variables:
h:to store the height in decimal
area:to store the area of the parallelogram
Member functions:
Area(…): parameterized constructor to assign values to data members of both the classes
void doarea():compute the area as (breadth*height)
void show():display the data members of both classes along with the area and perimeter of the parallelogram.
Specify the class Perimeter giving details of the constructor(…) , double Calculate() and void show(). Using the concept of inheritance, specify the class Area giving details of the constructor(…) , void doarea() and void show().
THE MAIN() FUNCTION AND ALGORITHM NEED NOT BE WRITTEN.
