To call a function written in C++ from C, you need to use the extern "C" linkage specification in C++. This tells the C++ compiler to use C linkage for the specified function(s), which prevents the compiler from mangling the function names (a common practice in C++ to support function overloading). Here’s how you can do it: ### Step 1: Declare the C++ Function with extern "C" In your C++ code, you declare the function you want to call from C with extern "C" to specify that the function has C linkage. This is often done within an extern "C" block, which allows multiple functions to be specified. You should also ensure that this block is only processed when compiling with C++, as C does not understand extern "C". C++ side (mycppcode.cpp and mycppcode.h): // mycppcode.h
#ifdef __cplusplus
extern "C" {
#endif void myCppFunction(); // Declare the function you want to call from C #ifdef __cplusplus
}
#endif // mycppcode.cpp
#include "mycppcode.h" void myCppFunction() { // Implementation of the function
} ### Step 2: Call the C++ Function from C On the C side, you include the header file where the function is declared and call it as you would with any other C function. C side (myccode.c): #include "mycppcode.h" // Include the C++ header with the function declaration int main() { myCppFunction(); // Call the C++ function return 0;
} ### Step 3: Compile and Link When compiling and linking, ensure that the C++ compiler knows to compile the C++ code and the C compiler to compile the C code. Then, link them together. For example, using GCC: 1. Compile the C++ code to an object file: g++ -c mycppcode.cpp -o mycppcode.o 2. Compile the C code to an object file: gcc -c myccode.c -o myccode.o 3. Link the object files together into an executable: g++ myccode.o mycppcode.o -o myprogram In the linking step, use the C++ compiler (g++) to ensure the C++ standard library is linked correctly, especially if your C++ code requires it. This process allows you..

What's the best stack {combination of languages and or frameworks}to go with with c++ ?

What's the best stack {combination of languages and or frameworks}to go with with c++ ?
Short answer: it depends.
Long answer: you can only determine it seeing an exact goal. Are you doing gamedev? Backend? Frontend? OSDev? Whatever that you are doing, just Google "C++ <your field> best guides" or something like that and research for a bit. As soon as you have more exact questions, come here again and ask them.

Build a program using call by value and call by reference. In C anyone help me i clg test tomorrow

Mhm how many C coders here?

So that would imply there are 12000 C++ Coders

Nah, most C++ devs are also C devs, just not every one in there is active on their Telegram account

Glad seeing you being energetic and being around;) although the group probably has become “stillwater”, I hope you are not affected at all and I hope that you are enjoying more things than before. (Although I don’t really know what the groups were like before)…
Anyway, I don’t know if all groups on telegram have kinda already lost a connection to people’s struggle either to technical problems or other things, but I wish there will be a new, refreshing way for people to connect, maybe even towards a better direction 👏

Well... I mean, I wouldn't be any efficient writing C unike with C++. Imo C++ and C are substantilly different at this point

Hi there! I'm just wondering if the language of visual basic, in any possible way, belongs to the C family?
And as for the Russian sentence I wrote before, it is more of a reply to the disappointment in the "missing" of vigor in groups: that everyone feels shy one way or another, but the most famous case should be those who ask questions or for help. I think that might also be the reason that people don't want to show up here: they feel shy asking real people, especially with the existence of AI assistant nowadays. Many people would say: only ask me questions after you have "fed it" to all of the following things: google, AI and... (as for the last one I couldn't really recall but you got the idea;)

Definitively no. BASIC (a language which VB is derived from) appeared in 1964, while C - in 1972
Ocean
This language feels not used anymore, at least it's not popular or making people feel cool about it in any way:(

Thanks for the interesting information here... The only thing I know about it is that it has been used more than 20 years. But didn't know that it came out way earlier than even C

Hey, here it is less of a lack of vigor and more of trying to stay matter of factly in the on topic
BASIC is not a language of the C family, it is its own slightly older family of languages.
Yes, there is some (reasonable) expectation you tried to understand your problem alone, it has nothing to do with AI, unless you think it was any different 20 years ago (in which case you are welcome to time travel there and check for yourself, but http://www.catb.org/esr/faqs/smart-questions.html had its first version in 2001)
I honestly think that AI should be the last recourse to solve a problem, after people, but google, forums and experimentation should indeed come before going to other people

Go and use Raylib and make a small version of Snake to get a feel for the language, then try and refine it to make it cleaner and easier to read. When you are done, reimplement it like you feel you should have done, then when you get disillusioned go and reimplement it again the right way

The debugging hell is entirely unrelated to C or C++ and entirely related to Forth

So many problems can be instantly solved by just using an object pool and not using inheritance

Is C++ can also be used for hardware programming
Do you really mean hardware programming (as in FPGA programming) or embedded programming (as in microcontroller programming) ? C++ cannot do hardware programming but it can do embedded programming, operating systems programming, systems programming and game programming quite easily, web programming too with some difficulties

I thought you mean embedded. And then yes.

There're very good features in modern C++ that make it much more appropriate than C.
Abbasi
Smaller binary size, more performant, less error prone, high readability/maintainability and more.
Abbasi
@b_aaz What are you laughing at? 😄
B
@b_aaz What are you laughing at? 😄
Very bold of you to claim smaller binary size, high readability, maintainability and performance as attributes of C++ when compared to C .
Abbasi
There're good features like below in modern C++:
constexpr variables and functions ...
if constexpr / if consteval
consteval functions
concepts/requires
templates
And more
These can help with this.
If you're interested into having a more detailed explanation, let me know and I'll give you a thesis (which is kind of a book) and elaborate on these.
The author also make accurate measurements to demonstrate the claims

Yeah templates help with readability 🤣 .
All those things you mentioned also generally increase binary sizes by inlining more code.
A thesis is not a "kind of a book".
None of the points you mention also point to C++ having "higher performance", whatever that is, compared to C.
So yeah please give me a more detailed explanation.

Well, if you do embedded, don't use any templates from STL.
Most likely this would be the C++ you want to use https://gist.github.com/bkaradzic/2e39896bc7d8c34e042b
