What does the compiler do and how to stop it?

Question

C++ / C#

Hello.
Student, 1st year.
This is the second time I've started the work of classmates when they ask for help, and the compiler does something incomprehensible to me.
Tough bearded C++ guys, don't get mad at seeing this.
I proceeded from the thought that you once also studied and probably also used CodeBlocks.
As I understand it, because of conio.h, which for some reason was included, but what should I do now?
I close all files and all projects, but now after every attempt to start something the editor tries to connect conio.
How to stop it? :D

Answer 1

I didn't quite get the point. Does the compiler throw an error? If not, then the conio.h file is included from the source.

I hope I understood your question correctly :)

Answer 2

This happens with recursive inclusion. For example, in the main.c file, instead of #include "main .h ", it says #include "main .c ". The compiler always includes a file that refers to itself and cannot stop.
Treat by finding such a file and fixing the error.
