I didn't fully understand "stdio.h" file. Is it something we should write? Or xcode writes it for us? If it is a system file why we have to indicate it?

1 Answer

It is the standard C library for input/output operations. If you import this to your app you can use the provided C methods to access files, to access the console etc. You do not have to write it, it is provided to you by the system or included.

Okay, i understand know. Thanks for your answer.
