Izinhlelo eziyisisekelo ngePseint (ingxenye 2)

Lokhu kufakwa kungukuqhubeka kokungenile kwangaphambilini (Izinhlelo eziyisisekelo ngePseint (ingxenye 1)) futhi iyingxenye yochungechunge lwezifundo ezinhlelweni.

Ukuze wenze uhlelo kuyadingeka ukuthi iPseint ihlelwe kahle, uma konke kulungile, singaqhubeka nalesi sifundo esigxile ngqo ekufundeni ukuthi iPseint isebenza kanjani ukuqala ngezinhlelo.

Uma sesiqalile sizobona izingxenye ezilandelayo:

1. Imiyalo: (yiyo engakwesobunxele) lapho kukhona imijikelezo eyisisekelo, imisebenzi kanye / noma imibandela.
2. Ibha yesimo: (lena engezansi lapho ithi "Azikho izibuyekezo ezitholakalayo") le bar ibonisa isimo samanje sePseint.
3. Indawo yokusebenza: yingxenye enkulu kunazo zonke, yilapho sizobhala khona uhlelo lwethu.

Lezi yizona eziyinhloko, ezinye ngeke zibe wusizo okwamanje

ALGORITHM IN PSEUDO-IKHODI

Inqubo engenasihloko isenzo 1; isenzo 2; ... ... ... isenzo n; Inqubo Yokugcina

Le yindlela ejwayelekile ye-algorithm, njengoba ubona, iqala ngo- "Process [SinTitulo]" ekhombisa ukuqala kohlelo futhi iphetha ngo- "EndProcess" ekhombisa ukuthi uhlelo seluphelile.

EZAHLUKENE

Okuguqukayo kuyimikhakha yememori egcina imininingwane ethile futhi ekhonjwa ngegama elithile elibhekisa kulezi zikhala zememori. Ku-Pseint ungachaza okuguquguqukayo ngezindlela ezilandelayo:

Ngophawu olulinganayo ukuze «a» kube okuguqukayo okuthola inani lokungeza i- «c» plus «b»

a = c + b;

Enye indlela ngesibonakaliso sesabelo (esizosibona ngokuhamba kwesikhathi, okwamanje sidinga ukusazi kuphela) futhi siyefana naleso sangaphambilini ngomehluko wokuthi yisibonakaliso esihlukile

a <- b + c;

Lezi zimpawu aziceli noma yiliphi inani kumsebenzisi ukuthi azi ukuthi yiliphi inani okufanele alibeke ngoba lokhu kwenziwa ngomsebenzi othi «funda»

AMALUNGISELELO

Amalungu afanayo ukulandelana kokuguquguqukayo kobubanzi obuningi okungagcinwa ngendlela yebhodi noma i-cube, lapho okuguquguqukayo kubizwa ngokuhlonza okujwayelekile nenombolo kuhlelo lwendiza yeCartesian. Ukufika ku-Pseint kuchazwa ngomsebenzi "wobukhulu" esizophinde siwubone ngokuhamba kwesikhathi.

Kulokhu isihlonzi esijwayelekile kuzoba ngu-var y nenombolo ibe ngu- "x" no- "y" okungaba ngu- [1,1] noma u- [2,1], njll.

Ubukhulu var [x, y]

Ngemuva kwalokho ukubiza okuguqukayo ongakusebenzisa

 i-var [x, y]

Lapho u- "x" angaba ngu-1 futhi u- "y" angaba ngu-2 khona-ke kuzobe kubiza u- "var [1,2]" okungazimela ngo- "var [1,1]", njll.

ABASEBENZISI

Ama-opharetha njengoba igama lawo lisho ukuthi yizimpawu ezisebenzisa amanani athile ukunikeza umphumela, Ama-opharetha ePseint ayalandela:

1. Kukhulu kune ">"
2. Ngaphansi kuka- «<«
3. Kuyafana nokuthi "="
4. Ngaphansi kuka noma kulingana nokuthi «<=»
5. Kukhulu kunokuthi noma kulingana nokuthi "> ="
6. Ihlukile ku- «<>»
7. Ukuhlangana (futhi) "Futhi" noma "&"
8. Ukuxuba (noma) «NOMA» noma «|»
9. Ukuphika (cha) "CHA" noma "~"
10. Faka "+"
11. Susa «-«
12. Ukuphindaphinda "*"
13. Ukuhlukaniswa "/"
14. Ukunikezwa amandla ^ ^ »
15. Modulus (okusele kokuhlukaniswa) «%» noma «MOD»

Isikhundla (ukuhleleka) kokusebenza kuyefana nalokho kwe-algebra futhi kuyashintsha ngama-parentheses. Endabeni yama-opharetha anengqondo, umsebenzi ufinyezwa okwesikhashana, opharetha u- "HAYI" uguqula umphumela.

Kulolu hlu kukhulunywa kuphela ezizosetshenziswa, ukubona uhlu oluphelele ungaya kwimibhalo yePSeInt.

IMISEBENZI

Ohlelweni, umsebenzi uchungechunge lwemiyalo enikeza umphumela othile futhi engathola inani elithile lokwenza umsebenzi okufanele bawenze. Ku-Pseint umsebenzi ubhalwe kanjena:

Inqubo engaphansi [ukubuya okuguqukayo] <- [Igama lomsebenzi] ([Izimpikiswano]) isenzo 1; isenzo 2: ... ... ... isenzo n; Qeda i-SubProces

Kulungile esifundweni esilandelayo ngizogxila kuyo yonke eminye imisebenzi kanye ne-syntax yayo ngaphandle kwabasebenza okukhulunywe ngabo lapha ngoba i-syntax yabo icishe icace.
