Hi All,
I am new to the software languages and wanted to learn C++. It seems that C++ is neither(complet ely) an object oriented programming nor(completely) a proceduarl programming. So, I was wonderinmg what is the diffrence between object oriented and procedural programming. Can anyone of you, please, let me know the difference as soon as possible.
Thanks and regrads,

Procedural programming means breaking your program into functions; where each function performs an specific task. You pass data back and forth to these functions, each function processes the data just a bit. Hence functions are the basis of the code and data plays a secondary role.
So this might be called "Functions Oriented" programming, or if you will, "Procedure based" programming AKA Procedural Programming.
With Object Oriented Programming, the data has bound functions (known as "methods") that process the data they are bound to. So you no longer pass data back and forth between functions, you just call the functions that are bound to data (albeit you still may pass parameters as extra information for these functions to perform more specific tasks).
You might call this "Data Oriented Programming", but in OOP, the data that has bound functions is known as Object, so it is called "Object Oriented Programming".
By the way, with a little bit of effort you can do OOP in raw C language.

I've always felt that procedural programming was putting everything inside the main() function...I guess you learn something every day.
Not quite correct:
With Object Oriented Programming, the data has bound functions (known as "methods") that process the data they are bound to. So you no longer pass data back and forth between functions, you just call the functions that are bound to data (albeit you still may pass parameters as extra information for these functions to perform more specific tasks).
You might call this "Data Oriented Programming", but in OOP, the data that has bound functions is known as Object, so it is called "Object Oriented Programming".
The above is true for all object programming. Unfortumately, there are two kinds of object programming: a) object-based and b) object-oriented.
In object-based programs, objects are created and their methods are executed as needed. That is, you create the object and you tell the object what to do.
In object-oriented programs, objects are described within a hierarchy where the top level is a general object and each suceeding level contains specific kinds of that general object. What you do here is create a specific object but use it as the general object when you make a function call. The function believes it has a general object but when the object is asked to excute a method, it is the method in the specific object that executes. In this manner, the same line of code referencing a general object can do many things based on the particular specific object in use at the time.
This substitution of a specific object for a general object is called polymorphism. Using polymorphism is commonly called object-oriented programming.

Hi. I'm new to this group. I'm refreshing/learning C++ and am starting to
learn Object Oriented Programming (OOP). In discussing this with people I
came up short as to what the benefits of OOP are. For example: As I
understand it, OOP has its main benefit in software reuse. Thus one develops
a software library of classes and this cuts down the overhead of reinventing
the wheel. Someone might say that this can be done with structured...

Hi,
I have been using C++ a lot and I've almost forgot what syntax is
support by C and what syntax is support by C++? My feeling is that C++
gives programmer much flexibility. And the code is more localized in
C++ than C, which mean changes won't propogate far away in C++ code. By
reusing through inherence and overloading, a lot of code can be saved.
But I have to use C for some reason. Is there any programming paradigm
in C, which...

I am developing an asp.net app based on a previous asp application.
in the asp applications global.asa file I had several
<object id="id" runat="server" scope="scope" class="comclass"> tags for
objects that the app used to speed up some global level data access and
functionality.
I have recoded the class libraries in .net and would like to acomplish the
same functionality in asp.net.

Hi fellows,
I am reading some books to learn the C programming language, and
sometimes I have the feeling that when somebody becomes a C expert, he
must learn a more modern and object-oriented language.
When I read things like "... C++ is an evolution of C ..." or "... C
is a subset of C++ ..." I tend to believe that I will have to learn C+

i have some confusion over this.
sure a class is basically a classification, like for example an animal
or flower. and an object/instance of that class is then for example a
cat.
an object is an instance of a class. that i know, i also know how to
program with classes etc.
i am just confused about the term object-oriented.
