SDL not printing to console

I'm trying to use SDL with Visual Studio 2019 but my programs are only showing an empty console. At the moment I just want to be able to compile my program with the SDL libraries.

#include <iostream>
#include <SDL.h>

int main(int argc, char** argv)
{
    std::cout << "yee haw!" << std::endl;

    return 0;
}

This code is just giving me a console with the text:

(process 32) exited with code 0. To automatically close the console when debugging stops, enable Tools->Options->Debugging->Automatically close the console when debugging stops. Press any key to close this window . . .

Where I would want 'yee haw!' preceding it.
It works fine when I take out the #include <SDL.h> (but I want the SDL.h)

I've heard that SDL now redirects to a stdout.txt file but I couldn't find that anywhere. I've also tried displaying a window with code from a tutorial I found, but that also gives me the empty console.

I'm using Visual Studio 2019 on Windows and SDL 2.0.9

Thanks!

By default, SDL uses a macro hack to replace the main function. The user defined main function must be in the following format:

int main(int argc, char** argv)
{
    // whatever
    return 0;
}

Alternatively, if you don't want this behaviour you can use SDL_SetMainReady.

#define SDL_MAIN_HANDLED
#include <SDL.h>

int main()
{
    SDL_SetMainReady();

    // whatever

    return 0;
}
