		//The frame rate as string
		std::stringstream caption;

		//Calculate FPS
		caption << "FPS : " << frame / (fps.get_ticks() / 1000.f );

//The Ultimate Event Handler !
void event_handler()
{
	while(quit == false)
	{
		while(SDL_PollEvent(&event))
		{
			if(event.type == SDL_QUIT)
			{
				//Quit the program
				quit = true;
			}
		}
	}
}

The caption didn't change,but when I close the program,the fps flashed on the caption then the window vanished.Why ?

Thanks in advance.

event_handler() will hold on your program until you close it.
