What's the difference, really?
Hello,
I want to know from a programmers point of view "what is the difference of c and c++, really?"
Is one harder or easier to write and read vs. the other?
Is the keywords easier to remember vs. trying to memorize all the ones for c?
what ?!?!
peace out

Just depends on what you are working on I guess. The syntax is obviously different but that is minor.

C is a subset of C++.
The difference is C is not an Object-Oriented language, C++ is.
An Object-Oriented language is one that provides the facilities
to do implement Object-Oriented programming.
What's the difference? C is small and elegant while C++ only adds complexity and confusion without fixing the flaws that C has. So in the end you have the Algol-60/Algol-68 deal. I have nothing against C++, but this is my honest interpretation of its design.

My best code is written with the delete key.
This is just a matter of personal opinions and my opinion is not worth more then anyone else. I think that the actual solution are usally more elegent using proper C++ then C. The C code are usally cleaner to read but this is because it lacks alot of the functionality that C++ have with the STL and Classes. Once you start to add function pointers in structs and linked lists to solve what C++ does with classes and STL I think C++ makes more sense. C++ do have some flaws because of historical reasons and compability with C. Bjarne S have a good artical about this in the latest C++ developer magasin.

No, it actually isn't. I believe you have that backwards:Originally posted by The Dog

C++ is a subset of C. C came first, C++ was created from C (ie: based on it). Thus, C++ is a subset of C.
C++ is also not a true "object oriented" lnaguage. It can be used in OO design, but it is not truly objective. If it actually is, then explain where there base object is here, and why it is an object:
No, C++ is a proceedural language which has aspects of an OO language. It is not a true OO language. For that, take a look at SmallTalk (arguably the best OO language ever made, which realisticly all are based on--model wise, aspirations, etc), and Java.Code:int main( ) { return 0; }
Quzah.
Hope is the first step on the road to disappointment.
Well,
C and C++ are both very powerful languages,
and within some limits we can say that C is a subset of C++. this obviously means that C++ is bigger than C
C was designed compact by KR. C++ adds more functionality to it.
almost all code that compiles in C,compiles in C++ also.
this reason is not mine, one of my professors told me this:
Preformance of C goes down when the length of code exceeds 10k lines.. C++ outperforms C here.
also C++ is OO. so data is lot more secure in C++ than in C. Encapsulation,inherentence and polymorphism are there in C++ but not in C, as C not OO..
hope this solves ur doubt.
That is an interesting comment, because I thought C++ was converted to C by the C frontend before being compiled.Code:Preformance of C goes down when the length of code exceeds 10k lines.. C++ outperforms C here.
Would that be because of the ability to use OO principles should decrease the amount of code required to write some applications?

C++ is a specialization of the C programming language. The languages retain 'link compatability'. They are both standardized by a committe, who also updates the definitions.
C++'s OOP specializations are very broad based, more so than middleware langauges like Java and .net. However the middleware languages are pure OOP which doesn't mean a whole lot, just that every type is an object. Due to their frameworks reusable design the middleware langauges are specializations of C++.
The main difference between C and C++ involves design modeling. The two schools are, action based and, object oriented.
C code is not slower than C++ code, however professional C programmers use techniques to control design faults of the action based paradigm. These principals are rarely taught in most books.
this is all opinion, much like any design philosophy. C++ is the new version of C so you might as well think of them as one. It's better that way.
Once you have that down you realize you have these new features including classes. Classes are a great way to group functions and data together and separate that action from the rest of your code thus providing reusable parts and code cleanliness. many old-school types don't believe in those things but hey, I like them. It's just a nice feature added to the language and yes they should be considered the same language

From Bjarne Stroustrup's book, The C++ Programming Language 3rd Edition.Object-oriented programming is a technique for programming - a paradigm for writing "good" programs for a set of problems. If the term "Object-Oriented programming language" means anything, it must mean a programming language that provides mechanisms that support the object-oriented style of programming well.
There is an important distinction here. A language is said to support a style of programming if it provides facilities that make it convenient (reasonably easy, safe, and efficient) to use that style.
From the above extract, I deduce that C++ is Object-Oriented.
As for this
>> C is subset of C++
It's your call.

Is it possible to write a C program with lines like this ?
Code:f(x)++;
C and C++ are two different languishes and they should not be mixed. They look alike and most compilers accept both but you will get in trouble if you think that C is the same as C++. Learn both but only use one at the time.
