[SDL] have to use task manager to abort program

What am I doing wrong here? This is lifted code. When the program runs it produces a black screen with a geometric pattern which is fine. But it sticks, it can only abort with task manager:
Second, it has no border (which is what I want) but I would like to be able to toggle that rather than just watch it disappear b/c I use use 1920 x 1080 res.



Code:
#include<iostream>
#include<SDL.h>
using namespace std;

int main(int argc, char* argv[])
{
	if (SDL_Init(SDL_INIT_VIDEO) == 0) {
	        SDL_Window* window = NULL;
	        SDL_Renderer* renderer = NULL;

	        if (SDL_CreateWindowAndRenderer(1920, 1080, 0, &window, &renderer) == 0) {
	            SDL_bool done = SDL_FALSE;

	            while (!done) {
	                SDL_Event event;

	                SDL_SetRenderDrawColor(renderer, 0, 0, 0, SDL_ALPHA_OPAQUE);
	                SDL_RenderClear(renderer);

	                SDL_SetRenderDrawColor(renderer, 0, 0, 255, SDL_ALPHA_OPAQUE);
	                SDL_RenderDrawLine(renderer, 320, 200, 300, 240);
	                SDL_RenderDrawLine(renderer, 300, 240, 340, 240);
	                SDL_RenderDrawLine(renderer, 340, 240, 320, 200);
	                SDL_RenderPresent(renderer);

	                while (SDL_PollEvent(&event)) {
	                    if (event.type == SDL_QUIT) {
	                        done = SDL_TRUE;
	                    }
	                }
	            }
	        }

	        if (renderer) {
	            SDL_DestroyRenderer(renderer);
	        }
	        if (window) {
	            SDL_DestroyWindow(window);
	        }
	    }
	    SDL_Quit();
        return 0;

}
