Question

Please type the answer for i can copy it. Thank you very much.

-Question 1

Respond to the following in a minimum of 175 words:

Read the following pseudocode class definitions:

Class Plant

Public Module message()

Display "I'm a plant."

End Module

End Class

Class Tree Extends Plant

Public Module message()

Display "I'm a tree."

End Module

End Class

-Question 2

Given these class definitions, determine what the following pseudocode will display:

Declare Plant p

Set p = New Tree()

Call p.message()

-Question 3

Discuss how algorithms address object-oriented classes and objects.

Answer 1

// Definition of the class Plant
class Plant
{
   // public method message
   public:
       void message()
       {
           cout << "I'm a plant." << endl;
       }
};

// Class tree inherit from plant class  
class Tree : Plant
{
   // public method message
   void message()
   {
       cout << "I'm a tree.";
   }
};

// main function
int main()
{
   // created a plant class object
   Plant p;
   // assign plant p reference of tree object.
   // Derived object assigned to base class
   p = new Tree();
   p.message(); // called message function but plant will be called.
}

Answer3:
Object oriented programming is writing the code for the real time
object. For eg you can write the code to demonstrate the operation
of a fan so the code you are writing is actually the algorithm to operate the fan.
With help of object oriented programming you can you can write the
algorithm for the real time object eg: robots or blood pressure
measuring device.
