Ok but if i want to make a program using that library, do I have to include only the .h file or i have to include the .cpp too. Or do i have to Redefine all the functions again??

For c and Cpp programming, you will need to include the header files to compile. However, you will need the library to generate a executable

Riccardo

let me explain

Riccardo

I have a .h file and a .cpp file that implements the First file

Riccardo

How are those two files conected when i include the .h in One of my program

Riccardo

???

Maybe you should read how to compile programs here https://www3.ntu.edu.sg/home/ehchua/programming/cpp/gcc_make.html

Just write your implementation in c/cpp files, declaration in header and include headers to cpp where you use those declared methods

Riccardo

Ok

Igor🇺🇦

You've certainly already did this when you use standard includes

Riccardo

So the compiler Will find the file that implements the functions automatically

Riccardo

Am i right?

Igor🇺🇦

If they are in correct paths compiler with create one binary that includes all the code

Riccardo

Ok

Then, there are two process. The first is the compilation. During this process, it will be necessary the functions prototype, including header files. This process generates a .o for each .cpp. the linker generates a executable using every .o and external libraries.

Guards is term that is used for #ifndef with #define

#pragma once

Anonymous

Do you mean "extern var" ? It's a declaration of global variable that is defined somewhere.

afaik, you can define your variables and functions and etc in header files too... another variations is define them in your .cpp files...

#pragma once

Include guards is name for #define / #ifndef, not pragmas.

Yes you can. But the question wasn't about that

i mean, we can also prevent (guard) double header inclusion by #pragma once, too

sorry, looks like i quoting the wrong post

Yes, we can.

but

seems like there's someone asking: "do we just have to declare variables in header and define it in another file?" but i can't find that msg...

Sorry. Off-topic but I am curious and have been meaning to ask to someone for a long time. How do you manage to hide your IP? Using TOR/Proxy? I tried IRC a few times, and I saw many users have a custom domain instead of IP. But when I tried, my real IP was being displayed. As much as I'd love to user IRC (I really liked it), I didn't follow it because of privacy concerns. (I'd want to hide my IP completely even if I am behind proxy/TOR). If not here, maybe you could PM me?

I run ZNC (an IRC bouncer) on my server which hosts my website so it's hardly private

Alright. Thanks!

Yep

There are a few bots which provide that functionality

I don't want to bridge telegram with IRC and wasn't asking in that context. I was asking about IRC in general.
