What are header files in C++ ( PROGRAMMING TUTORIAL for beginners)

Рет қаралды 195,555

Күн бұрын

C++ header files are files that usually have .h extensions and they contain declarations of variables, functions... The implementation of those functions goes into the implementation file.
By doing this, if the implementation does not change, there is no need to recompile the implementation file, which would not be possible if everything was in one file.
This also gives us the option to reuse the functions that are declared in the header file in multiple .cpp files. In order to do that you just need to include the corresponding header file in the .cpp file that wants to use those functions.
In this C++ programming tutorial, you will learn what are header files, how to create your own header file, and how to include it and work with it.

I would advise everyone here that believes this wonderful woman is one of the best people online explaining coding topics to gather multiple sources when needing help understanding a particular coding aspect. I too struggle understanding code. I wholeheartedly believe sometimes it takes multiple people explaining a topic in their own individual way for us some times to really drive home a concept. That said this is my second video of yours Beauty that I have watched and you have really solidified my understanding on some things I’ve already “known” (or kind of knew). Solid channel and you got yourself a new sub. Thanks again.

Hello, my fellow Bosnian! :D I have come across this video totally by accident while looking for a header file explanation. I am very glad I did. I am also happy to see that we are in the same country, the most beautiful country in the world. I am starting with some ESP32/micro-controller programming, and it is hard to comprehend the C language as I have never worked with or studied it before, especially when most online tutorials are merely about copy-pasting code and writing lines of code without explaining it in detail. I am fairly knowledgeable and experienced in analog electronics, but have only recently started with digital. It took me some time to comprehend the markings on MCUs, had no idea what GPIO and others meant. Now it's code-learning time, and it is a steep learning curve. Na Bosanskom: SLUČAJNO sam naletio na ovaj video tražeći objašnjenje za "Header file", zanimalo me i ko je ova djevojka koja ovako lijepo i dobro objašnjava korake u programiranju, pa sam još jednom bio prijatno iznenađen, ako ne i šokiran, kad sam shvatio da se radi o Bosanki u Bosni. Svaka čast djevojko, želim ti svaki uspjeh i da imamo puno više takvih talentovanih kao ti (izvinjavam se ako te iz početka ne oslovljavam sa vi, za mene većina ljudi nisu stranci, pogotovo ne oni koji se bave naukom i strukom srodnom mojoj). Što se tiče kafe (kahve ;) ), volio bih da te lično počastim kad budem u prolazu. Imam jedan zahtjev/pitanje: trenutno radim na razvijanju pametne gradske rasvjete i zato mi je potrebno znanje u programiranju. Trenutno ne znam nikoga od stručnjaka ili studenata u tom području koji bi mogli pomoći, pa na tome radim sam, ali ide sporo, kao i svaki početak. Nabavka komponenata izaziva dodatno kašnjenje. Ako si zainteresovana ili znaš nekoga ko bi bio zainteresovan za ovakav projekat, možemo se kontaktirati. Izvinjavam se za ovako dug "komentar", inače gledam da pišem ukraće.
