SDL2窗口未显示

Question

我下载了Visual Studio并设置了SDL，并且正在初始化且没有错误。我试图创建一个窗口

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

int main(int argc, char *argv[]) {

    SDL_Window *window;

    //Initializing SDL
    SDL_Init(SDL_INIT_EVERYTHING);
    window = SDL_CreateWindow(
        "Name",
        SDL_WINDOWPOS_CENTERED,
        SDL_WINDOWPOS_CENTERED,
        800,
        600,
        SDL_WINDOW_SHOWN
    );

    SDL_Renderer* renderer = SDL_CreateRenderer(window, -1, 0);
    SDL_SetRenderDrawColor(renderer, 0, 255, 0, 255);
    SDL_RenderClear(renderer);
    SDL_RenderPresent(renderer);

    if (window == NULL) {
        std::cout<<(SDL_GetError());
        return 1;
    }

    SDL_Delay(3000);
    SDL_DestroyWindow(window);
    SDL_Quit();

}

对于我来说，该窗口只是没有显示，我知道它可能会快速闪烁，但是根据我的阅读，SDL_Delay应该将其保持几秒钟。我尝试将传递给它的值从3000更改为30000，但没有更改。
