C or C++ ? - Overclock.net

Yo

Well I'm wondering what one should learn first, C or C++ ?

I saw people on the net (youtube comments) saying to start with C++ and then C, I was like "huh ?"

I don't know the differances yet, but I'm sure C is less complex, and perhaps I'm wrong but C++ is just an extension pack lol ?

Anyway, I started learning the hello world, and strings and memory allocation for characters in C (3 little tutos), and I was wondering how to keep working my way up.

It looks more interesting than sudoku

Thanks!

C is more complex and a relatively low-level language. It doesn't have classes and many other things that C++ brings along. C++ was made after C as a sort of update (hence the appended "++." to increment a variable (say x) in C or C++, you type x++. Play on words of sorts.)

More info.

Overall they're similar in syntax for the most part, but I would focus on learning C++, and some C knowledge will come along obviously, but i doubt you'll end up using it that much.

Depends what you want to do with it.

As far as the whole C thing goes I started with C# then C++ and now C.

If you want to make GUIs then C#

I personally like C more than C++ but it's just a preference thing.

I also personally like stdio.h more then iostream. You can use C headers and C++ headers interchangeably if you want in a C++ project. You can code purely C in a C++ project if you want. Its up to you and whatever is easier for you to learn.

I think you should start off with C first and get that foundation down, that will help when learning C++ making it even easier. Overall though both are great languages and if you learn one or the other first doesn't really matter in general. I personally started with C, but I'm enjoying C++ even more.

That may be true but there are instances where the relationship makes you go "***?" When I was working on a parallel computing in C I accidentally used the C++ version of the compiler needed for MPI (mpiCC instead of mpicc). The fact is that the program compiled with zero issues and ran fantastic the first few tries. The program was made to do over a million loops though so when I upped the number of loops from a few thousand to about 200k I would get errors on a few runs. By 500k I could not complete a single run without an error. I re-wrote my code from scratch after trying to fix it for an entire week. I finally figured out that I was using the wrong compiler and had to turn it in for half credit late. That ended up being the difference in the grade level I got for that class too.

Long story short, you can use C with a C++ compiler no problem but sometimes there can be minute differences so if you are going to do anything complicated, like parallel computing through OpenMP, it is preferable to use the correct compiler. Sad part is that the book we used taught everything in C but our instructions on the compiler used the C++ version without specifying there was a difference so I thought I was using the correct one.

I always consider those scenarios "the real introduction to programming" if you haven't experienced long hours trying to work out a problem where you made the most mundane & smallest mistake then you haven't really been introduced to programming yet!

Learn C first. Before C++ was "C++" it was called "C with classes".

You can learn to write programs and make stuff happen faster learning c++ first.

You will understand what the what is really going on if you learn C first.
