c++ - SDL_BlitSurface() not displaying image? -

So I'm trying to display a bus image with the SDL library, but when I use the function SDL_BlitSurface () I do not use anything, and what I get is a black screen. I should also keep in mind that I have a .bmp file, source and executable file in the same directory.

  // SDL header #include "SDL / SDL.h" int main (int argc, char * args []) // // SDL starts SDL_Init (SDL_INIT_EVERYTHING); // SDL Surfaces are images that are going to be displayed. SDL_Surface * Hello = Faucet; SDL_Surface * screen = faucet; // sets the size of the window (length, height, color (bits), sets the surface in the software memory) screen = SDL_SetVideoMode (640, 480, 32, SDL_ SWSURFACE); // Load a .bmp image Hello = SDL_LoadBMP ("Hello.bmp"); // Apply loaded image to screen SDL_BlitSurface (hello, tap, screen, tap); // update screen sdl_flip (screen); // stop SDL Della (2000); // Removes the loaded image from memory SDL_FreeSurface (Hello); // SDL exit SDL_Quit (); Return 0; }    
 
 
 loadbump () is nonsense Install the SDL_image library  
  install sudo apt-get SDL_image SDL_image_dev   
 (Not sure about package names. Just use appropriate or synaptic To search or do anything    
 and include it in  
  #include "SDL_image.h"   
 you load your image > 
  SDL_Surface * Hello = IMG_Load ("Hello.bmp"); if (Hello!) {Printf ("Oops, something went wrong Done:% s \ n ", IMG_GetError ()); Exit (0);}   
  Important Note:  Note that you should always check the error and print the error.  
  if (!)  is  if (Hello == faucet) / Code>
