Question:
1. The main function in the do - while loop exit loop judgment had been input very troublesome
( think continuous input data, simulation cache unceasingly, until they want to stop judging from the keyboard input something out again),
2. InQueue function in two if judgment how changes can omit a,

If it is no good to think program change (bosses, forgive me, hope I can talk about realizing the function of cache this idea -
