This could give you some idea:

struct OBJECT {
 int x, y; // Position on screen
 BITMAP *objbmp; // Bitmap for this object
} object[20][20];

void draw_screen(BITMAP *bmp)
{
 int i, j;
 blit(background_bmp, bmp, 0, 0, 0, 0, SCREEN_W, SCREEN_H);

 for (i = 0; i < 20; i++)
  for (j = 0; j < 20; j++)
   blit(object[i][j].bmp, bmp, 0, 0, object[i][j].x, object[i][j].y,
        object[i][j].objbmp->w, object[i][j].objbmp->h);
}
