I'm a student and I can't run program in C (visual studio), when I include a library like stdio.h

Question

I'm in class where we're learning C, and a few weeks ago I noticed whenever I included any library with #include<stdio.h> an error takes place.

For this simple piece of code:

#include <stdio.h> 
#include <locale.h>

int main() { 
    printf("Hi"); 
    return 0; 
}

This is the error message:

Severity    Code    Description Project File    Line    Suppression State
Error   LNK2019 unresolved external symbol _main referenced in function "int __cdecl invoke_main(void)" (?invoke_main@@YAHXZ)   P2ficha4    E:\Programacao1\P2\P2ficha4\P2ficha4\MSVCRTD.lib(exe_main.obj)  1

and

Severity    Code    Description Project File    Line    Suppression State
Error   LNK1120 1 unresolved externals  P2ficha4    E:\Programacao1\P2\P2ficha4\Debug\P2ficha4.exe  1

This has been a really big set back for me, and I don't think my professor can help me on this one. I appreciate any help

Yes, I knew how to code before uni. I've looked at the documentation for the error but it doesn't seem very helpful — Henrique Araujo, Apr 28 '20 at 15:57
Here's the code I'm trying to run @anastaciu #include #include int main() { printf("Hi"); return 0; } — Henrique Araujo, Apr 28 '20 at 16:00
@anastaciu The stdio.h is a standard C library. It comes with visual studio. and I have no idea where to find it — Henrique Araujo, Apr 28 '20 at 16:03
What would you recomend me to do with it? Also, it seems like something is breaking the linkage. I created a new project, worked the first time. Pasted the professor's code and it stopped working. Then I tried only doing a printf and still didn't work — Henrique Araujo, Apr 28 '20 at 16:09
How did you create your project in Visual Studio? What is the project type? And what is the full name (including extension) of ***your*** source file? — Some programmer dude, Apr 28 '20 at 16:12
I was thinking the other way arround, so for C if you have a .cpp extension it wouldn't work, but a .cpp file with C code should work, though it shouldn't be used like that. — anastaciu, Apr 28 '20 at 16:13
I have .c extentions. Also, I figured out what was wrong! But thanks you all for helping me brainstorm. I really appreciate it — Henrique Araujo, Apr 28 '20 at 16:16

My partion of E was disconnected from C by root. I made the project in the same partion (C) that windows was installed, I also selected the "make solution as same directory of project file". It was working for all semester until now, I don't know what triggered it. Thank you all for helping me brain storm
