Yingani kumele usebenzise ezingeni eliphezulu ngezilimi izinhlelo?

Njengoba wazi, yonke imiyalo ngaphakathi ikhompyutha zidluliselwa umshini ulimi ekhethekile lapho opharetha ukulandelana eziyinkimbinkimbi futhi akusenjalo of amaqanda futhi abathandekayo. Lena ekahle kakhulu izimpahla ezisebenza ngogesi, lapho iyunithi kungachazwa njengendlela isignali ezingeni elithile, zero - ukuntuleka isignali ezinjalo. Nokho, ukubhala iziqondiso ukwenza imisebenzi eyinkimbinkimbi besebenzisa le khodi kuba nzima kakhulu, futhi ukuthola iphutha futhi kokulungisa amaphutha kumane nje akunakwenzeka. Ngakho-ke sisungule ekhethekile, kuwusizo kakhudlwana konjiniyela, izinga eliphezulu ngezilimi izinhlelo.

indaba

Uhlelo kuyinto ukulandelana imiyalo ejwayelekile, ukuqaliswa okuholela ikhambi umsebenzi othize. Ukuze i-computer yokuqala izinhlelo zalotshelwa ngqo umshini ulimi, base nzima kakhulu futhi kunzima ukuliqonda. Ngasekuqaleni kwawo - maphakathi 50-xx lokugcina, 20, ekhulwini sengathi Macro wokuqala owenza inqubo izinhlelo ehlelekile ngaphezulu, bese okubizwa ngokuthi inhlangano ulimi, ephinde wencike ikhodi umshini. Ukulandela ukuthuthukiswa ngokushesha ubuchwepheshe computer olusungulwe futhi okuthuthukisiwe uHlelo izilimi. Futhi phakathi-xx 50 uvele Fortran, le ephezulu ezingeni ulimi lokuqala agcwele izinhlelo. Ngo-1968, u-Nicholas Wirth ulimi olusha Pascal lwaqala, okuyinto kabanzi ukuklama futhi adale imikhiqizo software ezithakazelisayo nesamanje. Kwabe sekufika ulimi BASIC, ngesisekelo okuyinto esetshenziswa Visual platform into-ngamakhasimende Eyisisekelo. In the 70s kwakukhona omunye kabanzi kunazo ngezilimi namuhla - C, okuyinto sekuye kwasetshenziswa ngqo ohlelweni lwezinhlelo. Okwamanje, ukuthuthukiswa kanye nokusabalalisa a izinhlelo ephelele futhi enza izinto ezihlukahlukene into-ngamakhasimende, kanye nalabo izilimi ezisiza ochwepheshe ukwakha izicelo Inthanethi: HTML, PHP, java. izinhlelo Ubude mayelana ngezilimi ezingaphezu kwezinkulungwane ezimbili ezihlukene, isisindo ingqikithi okuyinto ngesimo futhi kungukuthi asetshenziswa amakhompyutha, kanye eziningi ezingeni eliphezulu ngezilimi izinhlelo.

ngezigaba

Ukwahlukaniswa elula uhlukanisa zonke izimali ekhona okuthiwa eliphansi izilimi izinhlelo, noma okuhloswe ngaso imoto, kanye nasezingeni eliphezulu izinhlelo izilimi, futhi umsebenzisi-centric. Umehluko omkhulu phakathi kwabo itholakala lokuthi ukuthi uhlelo eyabhalwa iqembu lokuqala lwezilimi (okungukuthi, Assembler futhi ngekhanda), kuncike ikhompyutha - noma kunalokho, processor iziqondiso zalo ze isethi. High-level ulimi lokwakha izinhlelo kwenza kube nokwenzeka ukuze uthole uhlelo lokusebenza eziyosebenza kunoma iyiphi ikhompyutha, kungakhathaliseki yayo hardware. Izimali nazo ezimbili ezinkulu amaqembu ezizwe nezilimi: zenqubo futhi okungezona nenqubo, lapho iyunithi is kuphinde kwethulwa kwesakhiwo nokusebenza, ukusebenza kanye okunengqondo.

Ngokuvamile, ngamunye uchwepheshe izinhlelo unazo yayo mayelana izilimi izinhlelo eziyishumi ezahlukene, lawo angawasebenzisa ukuxazulula imisebenzi ethize ngesikhathi. Ngokuyisisekelo, yebo, izinga eliphezulu ngezilimi izinhlelo, kodwa futhi nzima unjiniyela izilimi umshini ngamakhasimende kabanzi ukudala ezinye izingxenye software.
