SDL2 errors on Visual studio Code while setting it up

Question

I recently wanted to try out SDL2 using C and I followed this tutorial Once everything was done I ran the code but I came across an error I did search the web but I did not find any clear answer

.\main.c:1:22: fatal error: SDL2/SDL.h: No such file or directory
 #include <SDL2/SDL.h>
                      ^
compilation terminated.

This was my configuration for

c_cpp_properties.json

    "configurations": [
        {
            "name": "Win32",
            "includePath": [

I have also included the SDL2.dll in the root directory I have copied the 64bit folder of the SDL2

Thanks.

Edit: This is the code that was running in the main.c file

#include <SDL2/SDL.h>
//#include <stdio.h>
//#include <stdlib.h>


SDL_Window *window = NULL;
SDL_Surface *surface = NULL;

//The parameters in the main function cannot be omitted, or an error will be reported
int main(int arg, char *argv[])
{
    window = SDL_CreateWindow("SDL2 Test", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, 800, 600, SDL_WINDOW_SHOWN);
    if (!window)
        return -1;
    surface = SDL_GetWindowSurface(window);
    if (!surface)
        return -2;

    SDL_Rect rec;
    rec.x = 700;
    rec.y = 10,
    rec.w = 20;
    rec.h = 20;

    while (1)
    {
        SDL_FillRect(surface, &rec, SDL_MapRGB(surface->format, 180, 10, 140));

        rec.x += 6;
        rec.y += 2;
        rec.x = rec.x > 800 ? 0 : rec.x;
        rec.y = rec.y > 600 ? 0 : rec.y;

        SDL_FillRect(surface, &rec, SDL_MapRGB(surface->format, 10, 200, 120));

        SDL_UpdateWindowSurface(window);
        SDL_Delay((1.0 / 60) * 1000);
    }

    SDL_FreeSurface(surface);
    SDL_DestroyWindow(window);
    SDL_Quit();

    return 0;
}
