SDL C++ Turning sprites, Turning a corner with 2D sprites

But I can't think how to turn a corner with a sprite realistically, ie not just suddenly turning left after x seconds of holding the key down. The two solutions that I have thought of are, firstly, to animate the sprite, but I'm not great with graphics, and I wouldn't be sure how to make it look real still. The second idea I have had is, if its possible, to take the angle at which the sprite is moving in relation to the direction of the road and increase that angle based on time the direction key is pressed. I know I haven't provided any code, but if you could just show me the right direction i would be grateful. Thanks in advance. Trake

It will have to involve some transformation trickery though, and i am not sure this is provided by SDL. If it is, then that is what you should use Perhaps there are rotation functions, or perhaps you can 'project' your sprite onto a new one. Not sure what the terminology is, neither what SDL exactly offers. If you find out, let us (me) know !
