Several methods of delay processing for C + + program

(-) using the _sleep () function

Example: _sleep (200);//DELAY 200 ms

(ii) using the delay (int time) function (which requires its own implementation, not within the compiler)

36. Time (&start_time);
38. Do
40. {
42. Time (&cur_time);
44. } while ((Cur_time-start_time) < sec);
46. }

For example, the delay of 2 seconds can be this: Delay_msec (2000); or delay_sec (2);

It should be noted that DELAY_MSEC has a higher time accuracy (up to 1 milliseconds, depending on the compiler definition) because it uses the clock ().
