I appreciate your honesty. Saying "IDK" goes a long way. From my textbook it states that header files are the "Specifications" of a class and therefore include signatures and any information that a client of a class needs to know in order to use it. To me that sounds like the include should be in the header.

[@luigibarrinuevo9392]

almost like an expansion of the function prototypes and function definitions

[@SoLiDStretchDB]

According to my prof, you would include the header files in the implementation file. (Depending on what you want the user to have access to) Essentially a layer of protection. You can put them in the documentation file (file with the class) if you dont care about the user accessing the functionality of the header file

[@poakssa]

Logically you need to include a header file to a file that uses it. So for example if you use string in this particular document you would add to this document. This is because this way you can call this header file from any other file without worrying if it will compile or not. It just makes it easier...

[@tonysciple5472]

I prefer including library references in whatever header files and associated implementation files need them even if there are duplicates, along with #pragma once approach. The reason is that if you include a class from another program, then it will work even if the other program didn’t have an earlier library reference.

[@Jackaldev]

I usually put all of the includes I know I will need into a file called includes.h and then include that in all of the files that need it. I'm not sure if this is a bad practice or not but it hasn't failed me thus far.

[@adithyan4990]

You are a perfect tutor

[@wearemiddream]

you're great dude, loving these tutorials. thanks a bunch!

[@alternativvelol]

You include the header file in .h if you are not working with pointers. If you are working with pointers do class forward declaration in the .h file and include the same .h file in .cpp. That's how I learnt it

[@PunmasterSTP]

Calling? More like falling...down into the dumps, because this tutorial series is almost at an end. Thanks so much again for such a wonderful resource, and for a wonderful ride.

[@dvs9006]

Header files mostly go in header files but they can go in cpp if there’s no need for implementation in the .h file associated with said cpp file

[@n-o-i-d]

I would go with the Header file inclusion approach

[@ndiayemodou3474]

Hi Caleb how to inherit class with args in the constructor ?

[@variancewithin]

this one took me 3 DAYS to figure out why it wouldn't compile. turns out turns out I didn't put #include Teacher.h in Teacher.cpp! the error was "Error C2653 'Teacher': is not a class or namespace name" for anyone in the future who may need to know.

[@ghostek7792]

dang, user.cpp was never really shown, I have no idea where in this series this was made

[@benn-ee]

ok for the header files its like we have user header file and teacher so basically user cpp will include user.h and teacher cpp will icnlude teacher.h and now the tricky part we have to include user.h in teacher.h cuz it is linked to User class and we dont have to include user.h in teacher and both header files in main.cpp i hope u get it lol im bad with explainations

[@GohersWay]

Thanks Randy Yee 3 months ago (edited) ***** Doesn't "#pragma once" also do the same thing as what you added for the preprocessor directives?

[@nyanlauncher7350]

I just put the include in both files since I use #pragma once

[@r3nash]

You should upload these to git

[@obitouchiha1671]

Can you start using std? it looks really "scary" to look at the code as a beginner

[@xiaonaiheme]

great video

[@Casanova646]

Doesn't "#pragma once" also do the same thing as what you added for the preprocessor directives?

[@ZNhatAnhZ]

yes. we have a lot of method to do that stuff

[@andmoreduro]

With gcc compiler that doesn't work

[@HetanHawke]

big Hi from Algeria Mr

[@saladforbrains2335]

what editor are you using?

[@mohammedmhilal4129]

almost there

[@ayrtonestrella]

03:25 If it works, don't touch it haha
