C ++ - SDL not working

Question

I tried to follow this tutorial on the basics of displaying images using SDL. But when I run the program, it returns a blank screen. The image is in the correct directories, but it does not appear in the program. Am I doing something wrong? I would really like the SDL to work.

EDIT

Here is my code:

#include <SDL/SDL.h>

using namespace std;

int main(int argc, char *argv[])
{
    SDL_Surface *hello;
    SDL_Surface *screen;
    SDL_Init(SDL_INIT_EVERYTHING);
    screen = SDL_SetVideoMode(640, 480, 32, SDL_SWSURFACE);
    hello = SDL_LoadBMP("hello.bmp");
    SDL_BlitSurface(hello, NULL, screen, NULL);
    SDL_Flip(screen);
    SDL_Delay(2000);
    SDL_FreeSurface(hello);
    SDL_Quit();
    return 0;
}
