oop in C

if OOP is possible in C, why was C++ invented, when it could have simply been a third party
library that some company made for 'C'

does c++ do things that are just not possible in 'C' without a writing a large amount
of code, that would not otherwise be required with c++ ?

you can implement classes as structures in C but you really cant have the protection afforded by private and public members etc

Hi ankuratvb,

>> third party library
because C++ is a superset of and not just a library. Polymorphism etc are part of the language and not only linkage.

>>c++ do things that are just not possible in 'C'
function overloading is not possible in C, C++ uses a concept called 'name mangling' to differentiate functions.

sorry, this was for apakian :-)
OOP is *possible* in C, but it requires great discipline and many tricky macros.

Perhaps you were misled when you read somewhere that early C++ compilers just translated C++ into C.  That is a non-trivial transformation, not one you'd enjoy doing by hand.

i think there are something we can do easily in c++ but not in c:

1. inheritace.
2. operator overload. For example: operator >> ( ....)

I think those 2 things are very important point of OOP, but C doesnt support or just very fex.

Hope that will help.
Actually after C, the next step in the path of OOP was c with classes. It was nothing but a preprocessor sort of stuff which converts a "c with classes" code into a pure C code. It involved introduction of classes and inheritence too if I remember correct. This "c with classes" language was then used to go further and after a lot of efforts, it came out to be C++ what we see today.

The moral of the story is I don't see anything which can be done in C++ and not in C. What it just takes is a lot of investment in terms of time. What C++ provides is a framework for supporting user defined datatypes in exactly the same way it supports built-in types. This make programming more easy and maintainable.

Even you can imlement vrtual functions and inheritance and other stuffs in C but you never want to do so because its no use reinventing the wheel.
