[Powered by Google Translate] Quam quaestionem Precendence est quod faciemus opera nolunt?

2
00:00:10,540 --> 00:00:14,250
Utrum absolvendis math aequationes aut parsing lineas computer scripta,

3
00:00:14,250 --> 00:00:17,230
sunt severus praeceptis ordinis de ad quam nos adhaerere

4
00:00:17,230 --> 00:00:20,270
Vestibulum ut omnis populus idem posse.

5
00:00:20,270 --> 00:00:24,710
>> Primo off, potissimam regulam meminisse, praesertim in bug testis,

6
00:00:24,710 --> 00:00:27,680
est quod nos semper operari ab intimo parentheses extrorsum.

7
00:00:27,680 --> 00:00:31,120
Usura susicivus parentheses potest esse benevolens debugging ratione militari,

8
00:00:31,120 --> 00:00:34,640
tamen suus 'non bona ad hoc quod praxis lectica vestri codice cum unneeded parentheses.

9
00:00:34,640 --> 00:00:38,220
Tolle discendi tempus basic operator praelatio regulas.

10
00:00:38,220 --> 00:00:42,450
>> Secunda regula generalis est, quod cum operators aequalia habent priorty,

11
00:00:42,450 --> 00:00:44,820
vos simply solvere a sinistro ad dextrum.

12
00:00:44,820 --> 00:00:47,690
Cum de simplex math nos satus cum parentheseos,

13
00:00:47,690 --> 00:00:52,110
ergo multiplicatio et divisio, non denique additionem et subtractionem.

14
00:00:52,110 --> 00:00:54,400
Prius, multiplicatio et divisio,

15
00:00:54,400 --> 00:00:56,870
quia secundum essentiam idem facientes operationem.

16
00:00:56,870 --> 00:01:00,880
Post divisionem simpliciter ductae pretium inverse.

17
00:01:00,880 --> 00:01:04,300
Similiter, subtractionem est simpliciter addendo valorem negativum.

18
00:01:04,300 --> 00:01:06,150
>> Faciamus exemplum.

19
00:01:14,470 --> 00:01:18,300
Secundum ordinem praecedentiae parentheseos Lorem puteus. Novem minus I.

20
00:01:18,300 --> 00:01:23,410
Qui dabit nobis VIII. Tunc potest moveri ad divisionem et multiplicationem.

21
00:01:23,410 --> 00:01:27,450
Puteus 'solvere a sinistro ad dextrum. Sic X divisa per II est V.

22
00:01:27,450 --> 00:01:31,290
Habemus V temporibus VIII adessent, et dabit nobis XL.

23
00:01:33,230 --> 00:01:35,410
Et itur ad sequentia ordine praecedentiae.

24
00:01:35,410 --> 00:01:38,730
Sic erant 'reliquit cum III plus XL minus I.

25
00:01:42,400 --> 00:01:43,700
Iterum iustus absolvendis laeua in dextram,

26
00:01:43,700 --> 00:01:47,650
quia illic 'aequalis prioritate inter additionem et subtractionem.

27
00:01:47,650 --> 00:01:51,510
Possumus dicere III plus XL est XLIII, minus I est XLII. Ut 'noster responsum.

28
00:01:53,920 --> 00:01:56,730
>> Sunt II genera decrementum et incrementum operators;

Praepositionis formam et extrema consequat.

30
00:02:01,000 --> 00:02:06,130
In putnam forma, i + +, communiter usus est in pro plicaturas,

31
00:02:06,130 --> 00:02:10,500
dicitur illud ex quo vis praesens et incremented est.

32
00:02:10,500 --> 00:02:14,240
Sic valor erit tantum diversis tunc vicis variabilis adhibetur.

33
00:02:14,240 --> 00:02:17,910
Sed contra est quod vis praesens prae incrementa vel decrementa

34
00:02:17,910 --> 00:02:22,760
est incremented aut decremented primus, et tunc ponitur in expressionem.

35
00:02:22,760 --> 00:02:25,310
>> Lets capiatis exemplum cum integer x.

36
00:02:25,310 --> 00:02:27,220
Puteus 'statuerunt eam aequalis V.

37
00:02:27,220 --> 00:02:36,500
, Si per putnam operator super illud et dicere x + +, x in hanc lineam adhuc est V.

38
00:02:36,500 --> 00:02:39,230
Ut si daret eam quantitatem V imprimendi.

39
00:02:39,230 --> 00:02:42,540
Sed Pergentesque x1 facto pares VI.

40
00:02:42,540 --> 00:02:48,770
Hac igitur x = VI in praesens, et si eam volumus pervenire valeat typis VI.

41
00:02:48,770 --> 00:02:57,380
Si vero praepositionis usus operante + X x incremented, mox pretium sit amet.

42
00:02:57,380 --> 00:03:00,110
Unde in VII aequalis est ratio.

43
00:03:00,110 --> 00:03:04,750
VI et VII Incrementing utique et si daret nobis imprimendam valet de VII.

44
00:03:04,750 --> 00:03:09,160
>> Ultimum nuance in precendence qui nos mos inviso agit monstratorem notatio.

45
00:03:09,160 --> 00:03:15,050
In dereference operator, stella, habet prius moto basic math operators,

46
00:03:15,050 --> 00:03:18,550
sed non in putnam incement et decrementum operators.

47
00:03:18,550 --> 00:03:20,690
Ut inducat ad ultimum.

48
00:03:20,690 --> 00:03:24,500
Lets accipe integer x et statuerunt eam aequalis VII.

49
00:03:24,500 --> 00:03:30,540
Sed certe ut aequali regula oratio x et y.

50
00:03:30,540 --> 00:03:34,920
Ut nobis dereference y debemus adepto valor VII.

51
00:03:34,920 --> 00:03:39,380
Nunc in hac linea of ​​code, habemus aliquanto ambiguum situ.

52
00:03:39,380 --> 00:03:44,310
Sumus dereferencing y primum, deinde incrementing valor VII?

53
00:03:44,310 --> 00:03:48,300
An incrementing in monstratorem et tunc dereferencing eam?

54
00:03:48,300 --> 00:03:52,800
In facto, quia putnam incrementum operator praecedit

55
00:03:52,800 --> 00:03:55,370
in dereference operator, erant 'conanti ADCRETIO in monstratorem y,

Sic hoc est valde vanitas linea.

60

Si vel pretium velit incrementum VII,

61
00:04:10,250 --> 00:04:14,260
volumus habere ut positis dereference operator cum y in parentheses.

62
00:04:14,260 --> 00:04:17,290
Tunc posset ADCRETIO eam.

63
00:04:17,290 --> 00:04:21,089
Et cum non secundum ultima linea incrementing pretium nisl x,

64
00:04:21,089 --> 00:04:23,380
in ultima linea of ​​code volumus infact dereference y
