Subject: Re: Object Oriented ??
its not a simple concept really.
The idea is that everything in your program is represented as an object,
each object encapsulates either an entity or a particular set of
'functions' (functions as in jobs)
An object is represented programatically by a class - this has the code
to hold the information that makes up the object, and the methods with
which to access and manipulate this information.
For example, if you were to make a simple system that represented the
files of a doctor's surgery, you might have the following objects:
1. patient
2. doctor
3. reception
4. prescription
5. drug
...
the list could go on
if you take the patient example, that would include all the information
about an individual patient - name, address etc, maybe an array of notes
about each visit... all the usual patient details, and methods to add,
manipulate and view that data
then the reception class might hold some sort of list of patient
objects, and methods to access those, it might also hold list of doctor,
drug and prescription objects, one object for each real life thing. -
all these individual things are instances of that object
I hope that makes sense
