2019 LNK ERROR - How to resolve?

Question

I’m having trouble with Visual Studio 2017.

This comes up when I compile:

LNK2019 undefined external symbol _Winmain@16 referenced in function "int __cdecl invoke_main(void)" (?invoke_main@@YAHXZ) Win32project2

That was the code I wrote, simple just to start and test if everything was ok.

#include<stdio.h>

int main()
{

    int n = 0;


    scanf_s("%d", &n);

    return 0;
}

You need to mark your project as Console Application. It is interesting to read these two references: Creating a Console Application and Walkthrough: Creating a Standard C++ Program (C++).

There is an answer in the OS Is it possible to Convert a Win32 application project into a console application?. The most voted suggests changing the Linker to the /SUBSYSTEM:CONSOLE and change the build macro of _WINDOWS for _CONSOLE.
