    Code:

    r.x=16;//Removing this line clears errors

    That code on its own looks fine. Can you show some of the surrounding code?

    Code:

    SDL_Rect r;
    
    r.x=16;
    
    
    
    
    
    
    
    
    
    
    int main ( int argc, char** argv )
    
    {
    
        SDL_Init(SDL_INIT_VIDEO);
        if(Init(1)==false)
            {
                printf(SDL_GetError());
                return 2;
            }
    
    
        atexit(SDL_Quit);
    
    
        SDL_Surface* screen =SDL_SetVideoMode(600, 480, 32,SDL_HWSURFACE|SDL_DOUBLEBUF);
        if ( !screen )
        {
            printf("Unable to set 640x480 video: %s\n", SDL_GetError());
            return 1;
        }
    
    
    SDL_Surface *bg=load_Image("C:\\Documents and Settings\\Make.YOUR-6JNHHU0520\\Desktop\\C++\\SDL\\Game Engine\\img\\sky.png");

    You can't put actual statements, like r.x = 16 outside of function bodies. If you move that to main, it will fix that error.

    Declaring your SDL_Rect r as a global variable is a bad choice (in fact, i believe firmly that global variable should never be used except in really special case when there's no others options).

    That said, CrazyNorman gave the answer (answer i didn't even thing heh).

    It's one at night. I didn't really feel like going into the code too much.
