Importing header files about network-programming

[TrymNOHG]

@callumgran Does this apply even when I don't use other methods to build up a method in the .cpp file? For example, if I have a:

int square(int x) {...}
int add_squares(int x, int y) {
return square(x, y);
}

Here, it makes sense since I am using an earlier function and its declaration is placed inside the header file. However, in the functions I created, I never reused any functions, as it wasn't necessary. Is it just good practice to always include the corresponding header?

I don't quite comprehend what you mean. Could you be so kind as to show me some images that show your question?

@callumgran The issue you opened revolves around such an example. Here is the link: https://github.com/TrymNOHG/network-programming/tree/main/Additional%20Work. If you would like me to send pictures as well, I would be more than happy to!
