Help, i dont undestend why this code doesnt work

Question

#include <iostream>
#include "pch.h"
using namespace std;
int main() {
cout << "HIIII";
return 0;
}

Answer 1

Did you have the pch.h header in includes path? or current directory? did you get any error message? if you did, can you write it on your original post, it will help identify the issue ...

Answer 2

"pch.h" like "stdafx.h" is a precompiled header and auto-generated for non-empty projects for VS version >= 2017, AFAIK. It can be safely removed.
