Ok, well firstly OO is a programming paradigm. There are loads and loads of resources explaining this in more details, but basically its all about abstraction - the problem is broken up into distinct objects (which combine data and actions upon the data) and these interact. For an example consider a library - we could have a Book object, which has data title and author (strings), with actions being set the data, set the author, get the data, get the author etc... Then we could have another object called shelf which has data books and then have actions add book, remove book etc... This really is a very simple explanation, and theres lots more to it, if you are interested then consult some books. Theres also loads of debate about the advantages/disadvantages of OO and where it is most useful.
You are correct - C++ supports OO. When C++ was designed, the creator took C and added extensions to it - at that moment in time C++ could be thought of as C with some additions (the first C++ translators simply turned C++ code into C code for compilation!) - however, C continued to evolve (we current have the C99 ANSI standard) and because of this the languages diverged and there are now aspects of C which are not in C++ (because they came after this divergence.)
Both C and C++ are still very popular today and both continue to evolve.

Simple one line understanding,
C & C + +
C is probably the most computer programming language used to write professional-level software, though new programs written today are usually done with its object-oriented successor, C + +. Both are best suited to well-trained programmers with the knowledge, tools, and time to avoid some major pitfalls.

Unfortunately its really not that simple - Stroustrup himself describes C99 and C++ as siblings rather than C++ as a sucessor (which it is not.) For the major differences between C++98 and C99 I suggest you take a look at this website http://david.tribble.com/text/cdiffs.htmIt should be noted that there are plenty of (well known) programmers who perfer C over C++ for many of their tasks

1. c is not object oriented but c++ is object oriented concept.
2. C is procedural programming language
3. cin>> for input, cout<< as a output function
4. Scanf and printf are used.
5. In c we use #include<stdio.h>as inclusion file,while in c++
we use #include<iostream>as inclusion file.

6. C is an imperative language
7. In C we use malloc and free a huge amount - in C++ its the constructors and destructors more commonly.

Well i would say it in a very simple sentence C++ is a better organized programming language than C could ever dream to be. I know i can say C++ has great features like Abstraction, Encapsulation, Inheritance etc. which may confuse you, but understand this any complex program you write in C is very hard to debug if an error comes even for the core programmers, but C++ is pretty much easy. HOPE MY ANSWER HELPED YOU

there are lot of differences between c and c++.
1.in c language we use 'printf' for printing output and 'scanf' for getting the input
2.in c++ we use 'cout' and 'cin'.
3.the operators used in c are also used in c++, but c++ has some special operators such as scope resolution operators etc.,
4.in c there is no concept of exception handling or inheritence.

Not always - in C there are a number of different functions which will display and read input. An example is putc - the standard ones are defined in stdio.h 4.in c there is no concept of exception handling or inheritence.
Be careful here, statements like that are common - but not entirely true! There isn't the exception statement and block, but error handling is very possible in C and commonly implemented via longjumps, the C standard header file is setjmp.h for this. Inheritence? - well of course C does not have the OO concept but it is still possible to create "objects", manipulate them and provide all the services that inheritence honours - although all of this will look different to OO programming it still does the same thing.

The main difference between C and C++ is that C++ is object oriented while C is function or procedure oriented. Object oriented programming paradigm is focused on writing programs that are more readable and maintainable. It also helps the reuse of code by packaging a group of similar objects or using the concept of component programming model. It helps thinking in a logical way by using the concept of real world concepts of objects, inheritance and polymorphism. It should be noted that there are also some drawbacks of such features. For example using polymorphism in a program can slow down the performance of that program.
To finish this discussion, C++ applications are generally slower at runtime, and are much slower to compile than C programs. The low-level infrastructure for C++ binary execution is also larger. For these reasons C is always commonly used even if C++ has alot of popularity, and will probably continue to be used in projects where size and speed are primary concerns, and portable code still required (assembly would be unsuitable then).

Are you sure? I have been plenty of results where C++ programs are actually faster runtime than C. Compile wise, I would be surprised if there was a huge difference for any complex application

1)c is used to make small programs bt c++ is used to make large programs
2)c++ used the concepts of oop's i.e object oriented programing approach which include polimorphism, inheritence, object, classes.
c doesnt use the oops concept
3)in c++ main program call the subprogram throgh message passing bt
in c calling concept is used.

As of version 2.6.27, the Linux kernel is over 10 million lines of code. 96.4% is written in C (which by my calculations is 9.64 million lines), hardly what you would call a small program

C++ is a programming language which have some very helpful features to implement an object oriented design. Implementing an an object oriented design is C language is difficult, but not impossible.

Hello...
In C the objects i.e. variables mainly depend on functions, and the data which is stored in variables doesn't have any security,
whereas in C++ every thing depends on objects, now the objects control the functions that is why it is called Object oriented programming.

I beleive C++ is an expansion of the original C, as I know the lesser known C-- is a compact version.

Actually c is a procedural programming language which
cann't face the real world problem. It has some drawback
like a global data is shared by all function and if in a
large program it is find out difficult that which function
uses which data.
On the other hand c++ is an object oriented programming
language which eliminate some pitfall of conventional or
procedural programming language. It is a concept or
approach for designing a new software. It is nothing to do
with any programming language although a programming
language which support the oops concept to make it easier
to implement.
This is the main different between c and c++.

C is not object oriented language
C++ is a object oriented language. First u have to know what is OOPS.
Object oriented programming language is programming technique on objects. For clear description study about objects.
C++ implements inhertiance, Operator overloading, Data encapsulation and others.

The C programming language is a very universal purpose programming language. It is used to solve problems ranging from operating system kernels, over compilers to graphical user interfaces. C++ was an effort to extend and change the C programming language to defeat some of the common and big problems with the language. C++, is a much younger language than C.

The is number of difference in C and C++. First in C , It is a function oriented language and C++ is a object oriented programming language. In C++ user can create a class in C the user not need to create a class. C support the structure , enum data type where C++ can not support. C does not have the capability of the polymorphism, Inheritance where in C++ support the all the advantages.

The only thing to be careful of compiling c with a c++ compiler, is that they diverged quite some time ago and minor details are slightly different. Probably not noticable for many codes but can catch you out.

C++ was an improved version to C complete in the eighties to integrate OOP into C. C is a technical language while C++ is a non-procedural language. C was the C++ precursor. C++ tolerate the programmer to create classes, which are somewhat similar to C structures.

C++ is a fully object oriented programming language (OOP) based on C. C++ is the advance level of C. So if you want to understand that difference, you should read on OOP. A good place to start is hxxp: en. wikipedia. org/wiki/Object-orie… I like OOP is mostly useful when working with very hard Program. Because i am Good worker in C++.

language. and nose right c++ is the advance verso of c.

Below are some major difference between C and C++:
1. C follows the procedural programming paradigm while C++ is a multi-paradigm language
2. In case of C, the data is not secured while the data is secured(hidden) in C++
3. We can use functions inside structures in C++ but not in C
4. C uses the top-down approach while C++ uses the bottom-up approach
5. C++ supports function overloading while C does not
6. C++ allows the use of reference variables while C does not

Difference between C and C++ as under :
- C is not object oriented but C++ is object oriented.
- C use #include<stdio. h>as iclusion file and C++ use #include<iostreame>as inclusion file.
- C is a topdown approach while C++ is bottom up approach.
- C is the low level language while C++ is the high level language.

The main difference between C & C++ is the OOPS technology, C++ is an object oriented programing language, using which one can program using the objects that are been created. C++ have the provision of inheritence, constructors and class where as you will not find these in C.

C++ is the advanced version of C. C++ does not retain complete source-level compatibility with C. The main difference between C and C++ is that C++ is an object oriented where as C is just function or procedure oriented.

C is basically a procedural language and it works in structured manner. C++ is object oriented language and close to real world. By object oriented means that objects will be created to access different variables and methods.,
