pseudocode to C++ code;

I have this pseudocode, but what would this code look like in C++?

PID Control (pseudocode) 1. Initialise: P_error I_error D_error- prev_error o 2. Update: cur_error - difference between sensors on Arduino 3. Set: P_error cur_error 4. Set: I_error I_error + (cur_error x sampling_time_in_sec) 5. Set: D_error - (cur_error - prev_error)/sampling time_in_sec 6. Set: prev_error cur_error 7. Set: output= KpXP error + K 1x1 error + K d x K error 8. Set: next-speed = cur-speed output 9. sleep(sampling_ time_ in_sec or other units)
