#include "SDL.h" 
int main( int argc, char* args[] ) 
{ 
	 SDL_Surface* hello = NULL; 
	 SDL_Surface* screen = NULL;
	//Start SDL 
	SDL_Init( SDL_INIT_EVERYTHING ); 
	screen = SDL_SetVideoMode( 640, 480, 32, SDL_SWSURFACE );

	hello = SDL_LoadBMP( "hello.bmp" );

	//Apply image to screen 
	SDL_BlitSurface( hello, NULL, screen, NULL ); 
	//Update Screen 
	SDL_Flip( screen ); 
	//Pause 
	SDL_Delay( 2000 );

	//Free the loaded image 
	SDL_FreeSurface( hello );
	//Quit SDL 
	SDL_Quit(); 
	return 0;
