Writing Psuedocode

I have to do the following:

Design and write pseudo code for an abstract data type representing a rectangle (width and length). Add a way to compare two rectangles by comparing their area, and a function computing the biggest in an array of rectangles.

THis is what I have so far:

Declare Height of Reals
Declare Width of Reals
Declare Area of Reals
Declare A[100] of Reals
Write Enter the Height and Width of Rectangle (enter 0,0 to quit): 
Input Height, Width
Set Area = Height * Width
Set Count = 0
While Area <> 0
     Set Count = Count + 1
     Set A[Count] = Area
     Write Enter the Height and Width of Rectangle (enter 0,0 to quit): 
     Input Height,Width
     Set Area = Height * Width
End While

PsuedoCode is not an easy task for me:  Could someone please help me!  I am fairly new to programming and I am stuck!  Thanks ALIStart Free Trial
