This is such a silly question, but i'm a beginner programmer, and I was following along a youtube tutorial on how to make a digital clock in the C language, and before the main() function there was #include<windows.h>. My computer had an error and after looking it up, I found out that is a file specific to windows? I saw some others said there are ways to "replace" the file or something, but i'm not really sure what to do. Anything helps. Thanks for your time.
