Yintoni a compiler - inkcazo

Ukuba nje ziqala ukufunda kweenkqubo okanye nomdla nje umba, kuza uhlangabezana iliso angaqondakali elithi "emafini". Le mbono ebonakala eyoyikekayo uyakwazi ukoyikisa abantu. Eli nqaku liza kuzama ukufumanisa ukuba yonke into eyoyikekayo. Yintoni emafini?

Inkcazo kunye nembali nasisihlo

Ngamagama alula, i compiler yinkqubo esiguqula itekisi yomgaqo-nkqubo ebhaliweyo ngumsebenzisi kwezinye uhlobo oko kumlungele na ukuphunyezwa kwi computer.

Kwakukho inkqubo enjalo, kunye ekuzalweni iilwimi zokuqala kweenkqubo. Oku kwenzeka kwi 50 ubudala. Kubonakala ukuba ibali, apho ezinxulumene abacwangcisi kunye neelwimi kweenkqubo ebuyela iminyaka engaphezu kwama ezintandathu. Nangona term ezinkulu ezinjalo, le ntsingiselo inzululwazi yekhompyutha kuyo nayiphi na imeko ayikwazi kuqwalaselwa ngaphandle umhla okanye lisonjululwe. Ngokwahlukileyo koko, ngokuhamba kwexesha, kunye ukuvela kwamashishini amatsha kunye imisebenzi apho computers, kukho imfuneko yokuphuhlisa kumsebenzisi-ongumhlobo ulwimi olutsha, ngaphezu kweenkqubo. Ngako oko, kuba ezi lwimi kufuneka abacwangcisi. Windows, Linux, MacOS - uye uyilo esisesayo platform nganye.

isimiso ukusebenza

Ikhowudi yemvelaphi ebhalwe umbhekisi phambili ulwimi ekwinqanaba eliphezulu iguqulelwa kwiprogram kwi ulwimi okhethekileyo umatshini. Ikhowudi nto kuthiwa inkqubo ephunyeziweyo. It ingafakwa ziqhube nakweyiphi na icomputer, ngaphandle kokwenza naluphi na utshintsho ngaphezulu.

Simple, kodwa kunzima

Ngokwemveli, abacwangcisi kwinzululwazi yekhompyutha yenye yezinto ezisisiseko izinto esifana ngazo iinkqubo kunye zolwazi zokusebenza. Yintoni emafini? Oko ngengqiqo sisiseko yenzululwazi computer.

Ukusuka kwesinye uluvo oluthile, nto kanye isihloko esibalulekileyo sendalo iinkqubo ezinjalo kubandakanya inani elikhulu nemiba yeengcingane nobuchwepheshe ezinxulumene kweenkqubo. developers abaninzi bakholelwa ukuba isihloko ngokubanzi kakhulu enomtsalane kulo lonke yenzululwazi. Xa uhlelo iphuhlisa inkqubo elisombulula ingxaki, wabhala oko ngolwimi oluthile. Ngexesha lenkqubo yophuhliso, uthetha ngokwemiqathango ukuba kufutshane kummandla ngqo ukusuka apho kufuneka sijongane. Le khompyutha akaqondi into uxelela abantu. Oku uyakwazi ukufumana phandle kuphela izinto ngendlela elula, ezibandakanya amanani kunye variables iseli kunye neerejista, inkumbulo ezisisigxina nezexeshana. Yintoni emafini? Le yinkqubo ogama msebenzi - wokuguqulela amagama kufutshane kwisifundo umqambi ekwahluleni ukuba uyakwazi ukulawula ikhompyutha.

Lo mngeni ababandakanyekayo compiler Java okanye naluphi na olunye ulwimi lokuprograma. isahlakalo ngalinye ulwimi olutsha kukho imfuneko ukudlulisela ikhowudi ezibhaliweyo kuyo, kuloo fom ukuba baqonde computer. Kungenjalo, akazange enze. Ngapha koko, kusoloko kukho umsantsa lwesemantiki phakathi kwala magama abantu kunye nekhompyutha. Kuyinto ukuloyisa yaye lwenkqubo abacwangcisi ulwimi.

Ubunzima ekwenzeni

Abenzi bemeko- ezi nkqubo bajongene ezininzi iingxaki. Le ngxaki lwezesayensi sizibandakanya yemephu olululo concepts wedomeyini yesicelo. Le engineering kunye neengxaki zobugcisa ezinxulumene ekuphunyezweni kwalo umboniso.

ukudala umsebenzi emafini siqulathe ezininzi yayo ezingafani. Le nzima, kodwa imincili kakhulu kushishino, leyo bachitha ubomi babo badwelisi benkqubo ezininzi. Kwaye musa uzisole.

Iklasi kunye emafini

Mhlawumbi, abaninzi baye weva iilwimi ezifana C no C ++. Ngapha koko, ukuba omnye ethandwa kakhulu futhi eqhelekileyo. Oku elinzima kakhulu iilwimi lwenkqubo, equlethe izinto ezinamandla ekulula ukubonisa ingqiqo kwiinkalo isicelo, apho ababhekisi phambili ukusebenza. Umzekelo, kukho ingqiqo kweeklasi kunye nemisebenzi. Kubalulekile ukuba iilwimi ezininzi, kodwa C ++ ezenziwa kakhulu.

Umdwelisi nkqubo lula kakhulu ukudala umfuziselo ngoncedo lwezakhono. Emafini C for Windows okanye nayiphi na enye yokusebenza kunceda ukubonisa ezi zinto ezikwizinga eliphezulu le fom ukuba khompyutha uyayiqonda. baya kuphela ke kukwazi zokuzisebenzisa.

Nayiphi na ikhompyutha, kungakhathaliseki ukuba unamandla kunye nezintsonkothileyo ukuba kwakungekho, esisebenza phezu ilula kakhulu. Kodwa ingqikelelo eklasini kunzima, kuba nayo lula kakhulu ukubonisa izinto ezininzi ukusuka ubomi benene. Le emafini iguqula iingqiqo ezintsonkothileyo bakudala.

Design Compiler njengoko umsebenzi

Kwiminyaka yakutshanje, kukho umkhwa, xa nayiphi na inkampani enkulu, enxulumene kobugcisa bolwazi, avelise ulwimi yayo lokuprograma, ngoko ezinambuzelayo kwinginginya ezibanzi developers.

Kakade ke, kuba ulwimi ngalunye kufuna a emafini. Kwaye ke uqinile, njengoko umthetho, banike ngalwimi zimbi. Kodwa kukho kwakhona iqela elikhulu badwelisi benkqubo ezizimeleyo kunye neenkampani ngenxa yezizathu okanye omnye ufuna ukuba abacwangcisi zabo kwiilwimi okanye ukuphuhlisa iilwimi ezintsha yaye ngaloo ndlela, abacwangcisi kubo. Sitsho ngengqiniseko ukuba ingcali oye wazibhokoxa kule intsimi, ngokuqinisekileyo akanakuhlala ngaphandle emsebenzini.

Ngoko ke, ngoku kufuneka ukuba kucace gca ukuba lo emafini. Le yinkqubo-umguquleli phakathi umphuhlisi kunye nekhompyutha, ngaphandle apho osentsimini yenzululwazi computer naphi na.
