SDL uses the OS event system, which most of the time
acts like a state machine. Which means it only send events
when something changes.

bool left = false;
bool right = false;
bool up = false;
bool down = false;

Now if you get an Keydown event set the meaned boolean true
like Keydown Event + Left Key: left = true;

KeyUp Event + Left Key: left=false;

For the rest of the keys do the same or use SDL_GetKeyState.

Then in your loop simply asks if left == true the move left.
The same with the other keys.
