Uyini opharetha okunemibandela?

Ngo izinhlelo, kuba amakhono olimi hhayi kuphela, kodwa futhi ukuqonda ukuthi kufanele aphendule ngalokho okubalulekile. Kuyadingeka ukuthi kungenzeka yimpumelelo ukusebenzisana, futhi ngaphakathi sihloko uzothola ukuthi imvelo opharetha, kungani idingeka, iziphi izici. Kuzophinde kuzoxoxwa Imibandela ushintshele kanye nekhodi ekhelini, futhi okuyiwona sisetshenziswa.

Uyini opharetha okunemibandela?

Ngakho (noma, kungenjalo, imfundo legatsha okunemibandela) ibizwa ngokuthi umklamo ulimi lokwakha izinhlelo. Inikeza ukusebenza iqembu noma isethi. Kodwa lokhu kungenzeka kuphela uma isimo waphawula leqiniso inkulumo ethile okunengqondo noma imiyalelo etholakele umsebenzisi (imishini opharetha) e samuntu.

incazelo Jikelele isicelo

isitatimende okunemibandela isetshenziswa uma lenza noma ukuziba ezithile imiyalo (imiyalo ngaphansi) kuxhomeke ekutheni kukhona ukwenza zezici ezinquma. Ingase futhi ingasetshenziswa sinombono ekhelini. Ingenye imiklamo ezintathu eziyisisekelo, ezisetshenziswa izinhlelo ehlelekile.

isitatimende legatsha okunemibandela

Okokuqala ake digress kancane futhi khumbula imidwebo zithandwa Vasnetsov Victor Mikhailovich, "Knight ngaleso Crossroads", abhalwe 1878. Liveza iqhawe ababemi ezimpambanweni zomgwaqo kanye esacabanga ukuya. Ngokufanayo, opharetha esebenzisa ekhondishina. Ngakho, uma knight ngeke uvume ukuya kwelinye direction, kodwa uzokuya egatsheni elifanayo. Kukhethwa ingaba yinye kuphela. Uma sikhuluma opharetha okunemibandela ke kusebenza kuphela uma lubonakaliswa esinengqondo siwukuthi "iqiniso". izilimi Iningi izinhlelo ukuqoka lisebenzisa elisemqoka uma. Mhlawumbe esigabeni ukwakhiwa, uma ungenile kuqala isimo, kwalandela enye ke yesithathu, ingxenye yesine, nokunye. Ake sibheke le kabanzi. Yiziphi izinhlobo ezihlukahlukene zokubusa ngesimiso izitatimende okunemibandela? Njengamanje bobathathu:

1. isitatimende okunemibandela, lapho kukhona legatsha eyodwa kuphela. Kubukeka (okulinganiselwa ku) kanje: uma izimo ezidingekayo bese kwenziwa ekupheleni ithimba. Ikhompyutha sinquma imoto, kungakhathaliseki inani elinengqondo we inkomba weqiniso. Uma isimo kuyafana nalabo bezinye izingxenye zohlelo, uqala akhiphe ikhodi kuze kube sekupheleni elisemqoka. Ngo assembler lolu hlobo umsebenzi uyatholakala uhlelo kuphela. Kungase kube anjalo ukuthi ekugcineni kuzoba khona elisemqoka ethile, bese kudingeka uqaphe ukuba attribute eziseceleni.
2. isitatimende okunemibandela, lapho amagatsha amabili akhona. Kubukeka kanje: uma isimo inikezwe ke command1 command2 ekupheleni omunye. Sebenzisa le ukwakha izinhlelo ezimweni lapho kubalulekile ukuthi elinye lamaqembu eye eyenziwa ngokunembile. Ngakho-ke, uma isimo kuyiqiniso, khona-ke ingxenye yokuqala ikhodi - uma kungenjalo yesibili. Kwezinye izimo, ikhambi elinjalo kuyadingeka.
3. opharetha okunemibandela nge lezimo eziningana. Kubukeka kanje:
   uma isimo kuqala bese lokho ukwenza
   okunye uma uma isimo kuqala kungahlali, uhlole okulandelayo ke yini okufanele uyenze
   okunye uma uhlole yonke omunye izimo ngamunye ke yini okufanele uyenze
   okunye uma futhi kukho kusukela ngenhla akulungile ke umyalo is run ekupheleni

Njengoba ubona, opharetha okunemibandela isebenzisa design ehlukene. ukuqaliswa yabo senzeka ngokulandelana. Lokho akunakwenzeka isimo (at inqubo evamile), lapho ukukhishwa ikhodi uzoqala kusukela ekupheleni - njalo kusukela ekuqaleni.

Isibonelo "Pascal"

Ukuze uqonde ukuthi isebenza kanjani, siphakamisa ukuba sifunde ngesibonelo sika omunye ethandwa kakhulu izilimi izinhlelo. isitatimende okunemibandela ku "Pascal" kungaba lelula nobe lelukhuni. Uhlobo lokuqala - uhlobo izimpawu =, <,>, nokunye okunjalo. A eziyinkimbinkimbi isitatimende ezinemibandela Pascal kungathatha ifomu elilandelayo:

uma> = y
ke
Op: = Sqr (ay)
okunye
ukubhala (inani elingavumelekile);

Kuyini inkinobho?

Kuyini inkinobho? Isici nomklamo walo ukuthi inamagatsha okungenani ezimbili. Kodwa yena uyakwazi nje eyodwa, Ngaphambilini usethe nemingcele ukuthi basuke ngekhompyutha amagama ayinhloko. Ekhuluma Ngokungafani imiyalelo ngaphambili kufanele iphawule yakho yokuthi isihloko ingabuyeli value Izimiso eziphusile, futhi wonke, kanye nezinhlobo ezingaba asinikwe. It kungabuye kwenziwe kwezinye izilimi izinhlelo, uma kuqhathaniswa nabangu-amayunithi wezinhlamvu zombhalo.

Umlando yentuthuko

Ekuqaleni esetshenziswa iqembu, okubonisa ukwedlulela ithegi ibalwa. Wawuthi inkulumo, wenza kokubili njengoba isikhethi, okuyinto abuyise inenombolo, futhi iqoqo imiyalelo inguquko. Umyalo uyabulawa, ibalwa value othize, elisetshenziswa njengesibonakaliso inombolo ilebula lonke uhlu imiyalo okuyiwona kukhona ezihambayo nokunakwa umshini.

imiklamo Okufanayo kungabonwa ngezilimi izinhlelo ezifana "okuyisisekelo" futhi "Fortran". Asikwazi bethi kakhulu yisikhathi, ngoba kuze kube manje bangakwazi ngiziqhayise ephumelelayo kakhulu ngokwanele, uma sikhuluma ngokuvamile ngokuhlelwa kwezakhi. isitatimende okunemibandela esetshenziswa amaBhayibheli ezilimini zanamuhla, isakhiwo eziyinkimbinkimbi, esithinta ukusebenza. Ukuya emuva umsuka lento, Ngithanda ukwengeza ukuthi ukuzimisela amagatsha ezidingekayo Akubalulekile sequentially inqubo bese uqhathanisa umphumela ngelithi ezinye amagugu. uya nje kwirekhodi kwimemori afanayo imiyalelo legatsha olungenamkhawulo, lapho liqukethe ikheli lakho. Lapho liyisibonelo kudingekile ukuthi ulwazi oludingekayo omane ibalwa. Futhi ijubane uhlelo iba ezimele inani tags.

Ngo yesimanje izilimi izinhlelo, okuyinto kabanzi okwamanje, ukushintsha opharetha kungabuye yakhelwe njengendlela shintsha ithebula ehlanganisa amaqembu, okuyinto afeze ukuhamba ukunaka izingcezu kudingekile ikhodi ngaphandle kwezimo ezihlukahlukene. Kanjani ekumelelayo? I eliphezulu ngezilimi izinhlelo, ezimweni eziningi, zisebenzisa igama icala, swithc noma kokubili.

Izakhiwo ukubala izinkulumo Izimiso eziphusile

A elikhulu kanjani isimiso isitatimende okunemibandela eziyokhishwa, ihumusha yokutholwa esimweni ngasinye kathisha logic wokuboniswa okunemibandela. Kukhona amasu ezimbili eziyinhloko.

1. Qedela ukubala. Thina ukubala zonke nemingcele namagugu enikeziwe, bese I.
2. ukubala Akuphelele. Eceleni kubhekwe zonke option. Uma inkulumo ethi ihlola "iqiniso", ngakho-ke kukho elilandelayo bekhohliswa. It uba esimweni NOMA.

isiphetho

opharetha okunemibandela kukhona umklamo ukhululekile kakhulu izinhlelo. Ngosizo lwabo kungenzeka kalula liqalise imiklamo eziyinkimbinkimbi ngaphandle kokucabanga babantu.
