Algorithm Linear - umdwebo isakhiwo kanye ukubala

Impilo yansuku zonke njalo umuntu ukubhekana lenqwaba imisebenzi nobunzima emsebenzini obuhlukahlukene noma uma ngitadisha. Abanye imisebenzi elula kangaka, ukuthi ekusebenziseni kwabo senza izenzo ezithile ngokuzenzekelayo, ngaphandle ngisho ukucabanga. Isixazululo iyiphi inkinga, ngisho elula, njengoba umthetho, wenziwa njalo ukuze ngezinyathelo ezimbalwa nje. Lolu hlobo kusebenta nokuxazulula izinkinga ibizwa ngokuthi i-algorithm. Namuhla sibheka ukuthi algorithm yomugqa, isakhiwo sabo umelwe wenza isinqumo sabo futhi izinhlelo.

ulimi algorithmic

Lo mqondo kuwumuthi ngqo ngenxa yomculi ukuze ngekulandzelana kwetintfo letenteka, okuyinto siqondiswe ikhambi yenkinga.

Lolu limi kuyindlela yokuthola echaza algorithm ukuthi bagxile ngokuvamile kumsebenzisi.

Uma kuziwa ulimi ikhompyutha, njengoba kuboniswa kadokotela ngqo, belinganisa inqubo yezamakhompyutha. Yena, kuholela kusukela idatha kokuqala, kulolu khahlamba, kumphumela yasekuqaleni.

Ukuthuthukiswa kwe-algorithm - kuyinto kubenzima isikhathi inqubo. It iyiqoqo amasu (ukuthuthukiswa) ngekulandzelana kwetintfo letenteka, eklanyelwe ukubhekana nezinkinga ngosizo lwama-computer.

izakhiwo algorithm

Phakathi izindawo ezishisa kakhulu zikhipha izinhlayiyana:

• esitho - kuwukufezeka lonke algorithm ngokuchaza inombolo ezilinganiselwe izinyathelo (izinyathelo);
• Ngokuqinisekile (ocacile) - ubunjalo imithetho ukuhumusha ukwenza izenzo, futhi i-oda ngokubulawa kwabo;
• ukusebenza - imiphumela emihle ngoba noma iyiphi inombolo ezilinganiselwe izinyathelo;
• kucace - imiyalelo ecacile kumele kube obhekele;
• mass - algorithm kufanele bakwazi ukuxazulula isigaba izinkinga ezithile ekwakhiweni jikelele inkinga.

algorithm Linear. Ikhompyutha Class 9

Sesixoxile kakade ngemibhalo yencazelo nezakhiwo umqondo. Manje ake sixoxe izinhlobo:

• komugqa;
• ekhelini;
• nge umjikelezo.

Sinesithakazelo algorithm komugqa. Yiziphi? Ziqukethe imiyalo ukuze abulawe enye ngemva kwenye ilandelane ecacile.

Isakhiwo komugqa algorithm ungalotshwa ifomu lwamazwi sokuqhafaza.

Lapha isibonelo, esilotshwe ifomu ngamazwi. Ngakho, umsebenzi: Ukuqoqa esikoleni. isixazululo:

• Qala.
• Sukuma.
• Zivocavoce.
• Geza ubuso bakho.
• Ugqoke.
• Ukudla kwasekuseni.
• Qoqa iphothifoliyo.
• Ukuphela.

Isikhombimsebenzisi ukuma predsatvlyat ngenhla inqubo kuyoba kanje:

algorithm Linear e block umdwebo ifomu,

Isifanekiso block limelela okuyisibonelo isithombe algorithm lapho ngamunye isigaba ahlukene imelelwa amabhlogo amelwe ezihlukahlukene ngamajamo weJiyomethri. Ngaphandle kwalokho, ukuhlobana izigaba (ngamanye amagama, ukulandelana ngokubulawa isigaba) Kubonisani imicibisholo, okuyinto ukuxhuma izingcezu (amabhlogo). block ngasinye sihambisane oqoshiwe. Ngenxa yezenzo ejwayelekile elandelayo algorithm asetshenziswe komugqa ngamajamo weJiyomethri :

• Block isiqalo ekupheleni algorithm. On block kuyinto eliqoshwe umbhalo othi "ekuqaleni" noma "ukuphela".
• "Wokufaka-okukhipha" iyunithi. Lokhu block amelwe ngesimo parallelogram. Wabeka okucashunwe esilandelayo: "wokufaka", "ukuhoxiswa", "ukuphrinta". Futhi unamathisele kubo uhlu input noma, ngokulandelana, eziguquguqukayo okukhiphayo.
• iyunithi Aritmethikhi noma ukuvimba izinqumo. It kulingana isikwele. Isibonisi iyunithi kufanele: "ukusebenza", "iqembu imisebenzi."

Kodwa ngosizo block imidvwebo ukuboniswa isixazululo algorithm komugqa. Ngokulandelayo, ake sixoxe ngezici sabele amagugu.

algorithm Linear yezamakhompyutha

Main isinyathelo aphansi e-algorithm yezamakhompyutha - lesi sabelo lokwehlukile inani elithile. Esimweni lapho ukubaluleka njalo kunqunywa ukuma ukuqoshwa yayo, ukuthola value othize variable kuphela ngenxa lesi sabelo. Lokhu kungase ngokuxoxa izindlela ezimbili: esebenzisa isiqondiso isabelo; ngokufaka imiyalo.

Isibonelo algorithm ukuxazulula komugqa

Nasi incazelo isibonelo imithetho sesigaba kwamafrakshini nge algorithm komugqa ukuthi zesikole okuqukethwe:

• numerator we ingxenyenamba 1 kufanele siphindwe zihilela we ingxenyenamba 2;
• 1 i-zihilela ukuba siphindwe numerator 2;
• ufuna ukuqopha ingxenyenamba, ogama numerator kuwumphumela ukuqaliswa isigaba 1, kanye zihilela - umphumela amaphuzu 2. Ifomu algebraic lokhu kubusa simiswe ngalendlela lelandzelako:

/ b: c / d = (a * d) / (b * d) = m / n.

Ngakho, sakha i-algorithm ikhompyutha yokuhlukanisa izingxenyana zaso. Ukuze ugweme ukudideka, sizosebenzisa i eziguquguqukayo kukhona lefanako njengoba kule formula esiye esishiwo ngenhla. a, b, c, d- idatha yoqobo njengoba inamba eziguquguqukayo. Umphumela walokhu uyoba amagugu inamba. ikhambi ulimi algorithmic kungaba kanje:

SAL division kwamafrakshini

ekuqaleni

nezinhloso, b, c, d, m, n

iqondiswa a, b, c, d

m: = a d *

n: = b * nge

ukuhoxiswa m, n

umdlalo

Graphic format izixazululo

Isikimu komugqa algorithm ezichazwe ngenhla simiswe ngalendlela lelandzelako:

ukwabela Inani iqembu has ifomethi elandelayo:

Variable: = Inkulumo.

Isibonakaliso "=" kufundwa ayinikezwe.

Isabelo - iqembu, okuyilona elidingekayo ukuze umuntu ikhompyutha ezokhipha izenzo ezilandelayo:

• nokuhlola inkulumo;
• ukwabela amagugu variable etholwe.

I-algorithm ngenhla has imiyalo emibili njengoba isabelo. Ngo block umdwebo sabelo umyalo kufanele kuqoshwe isikwele, othiwa Computing iyunithi.

Lapho esachazwa algorithm yomugqa, asikho isidingo esithile ukuhambisana saziso nemithetho eqinile lapho ebhalela izinkulumo. Ungarekhoda kubo ngokusebenzisa ifomu evamile zezibalo. Kodwa lokhu akuyona esiqinile ulimi lokwakha-syntax.

Kulesi sibonelo, futhi i-algorithm ongene iqembu:

Faka a, b, c, d.

umyalo yokufakwayo ngempambano okulotshwe parallelogram, okusho ukuthi okufakwayo-okukhipha iyunithi. Lapho ekufezeni lo myalo, wokugaya iphazamisa kuze umsebenzisi siyofeza izenzo ezithile. Okungukuthi, umsebenzisi kudingeka kwidivaysi yokufakwayo (ikhibhodi) uthayiphe okuhlukile kokufaka (namagugu abo) bese ucindezela Faka, okuyinto uba u-Enter. Kubalulekile ukuthi amagugu zivakiwe ngekulandzelana efanayo ohlwini okokufaka, ise eziguquguqukayo okuhambisanayo.

algorithm Linear. izinhlelo zayo

Njengoba kushiwo ekuqaleni kwalesi sihloko, uhlelo lwento ingase ihlanganise amazwi anjengokuthi:

• isabelo;
• nokuthuma;
• isiphetho.

Okusho ukuthi, usebenzisa opharetha ngaphezulu ukuze izinhlelo lwento algorithm.

Ngakho, i- opharetha yomsebenzi ozokwenziwa ngolimi izinhlelo kulotshiwe kanje:

AKE A = B, lapho A - B variable - inkulumo. Ngokwesibonelo, A = Y + 20.

entry opharetha simiswe ngalendlela lelandzelako:

INPUT, isibonelo: INPUT C

opharetha okukhipha idatha, amagugu yalotshwa njengezingoma zohlobo oluthile:

PHRINTA. Ngokwesibonelo PHRINTA S.

Nasi isibonelo esilula. Sidinga ukubhala uhlelo uzothola inani wokufaka kusukela ikhibhodi izinombolo A no B.

A ulimi lokwakha izinhlelo, sithola uhlelo, umbhalo oboniswe ngezansi.

ukungena opharetha, okukhipha ku Pascal ulimi lokwakha izinhlelo

Pascal alikuvezi opharetha ekhethekile, okubonisa wokufaka noma okukhipha imisebenzi ezisebenzisa algorithm komugqa. Izinhlelo exchange kolwazi Kwenziwa ngosizo izinqubo esakhelwe ngaphakathi. Njengoba kungekho isidingo incazelo owandulelayo inqubo ejwayelekile, itholakala for Uhlelo ngalunye, oqukethe kuyo. Futhi igama inqubo wathi akusho kuphrojekthi iyiphi elisemqoka.

Uma ufaka idatha usebenzisa baqhubi sokufinyelela inqubo esezingeni kufakwa eselivele bafakwe ohlelweni.

Funda (A, B, C), lapho A, B, C - eziguquguqukayo ukuthi kufanele ifakwe ku-inkumbulo isitoreji.

Readlnn (x1, y, X2) - kokuqeda entry, isikhombisi ngendaba ekuqaleni umugqa omusha.

Readlnn; - likhombisa cindezela elinde «Faka». Ngokuvamile le opharetha ufakwa umbhalo ngaphambi juqu «End», ukuze ulondoloze imiphumela uhlelo okuqukethwe kwesikrini.

idatha lokukhipha esikrinini qapha ngokusebenzisa lezi opharetha:

Bhala (A, B, C) - ecacisa amagugu A, B, C umugqa owodwa, futhi isikhombisi akabashiyi umugqa wamanje.

Writeln (z, y, Z2) - ophela amagugu okukhipha, isikhombisi izoya umugqa omusha ngaleso sikhundla.

writeln; - kufakazela ukuba kudlule umugqa futhi bathuthele nokuqala kwesimiso esisha.

Kodwa ngosizo mazwi alula okunjalo futhi kwenziwe input bese okukhipha idatha ku Pascal.
