Yuav ua li cas yog ib tug compiler - ib tug piav qhia

Yog hais tias koj yeej cia li pib kawm programming los yog cia li xav nyob rau hauv lub qhov teeb meem, koj mam li yuav tuaj nyob ib mysterious qhov muag rau lo lus "compiler". Qhov no seemingly txaus ntshai tswvyim yog tau hem neeg. Qhov tsab xov xwm no yuav sim mus nrhiav tau tawm yog tias txhua yam yog txaus ntshai. Yuav ua li cas yog ib tug compiler?

Lus Txhais thiab keeb kwm ntawm tshwm sim

Nyob rau hauv cov lus yooj yim, cov compiler yog ib txoj kev uas converts cov ntawv nyeem ntawm ib qho kev pab sau los ntawm tus neeg siv nyob rau hauv ib co daim ntawv uas yog haum rau siv nyob rau hauv ib lub computer.

Muaj xws li ib tug kev pab cuam, ua ke nrog cov me nyuam yug ntawm tus thawj programming lus. Qhov no tshwm sim nyob rau hauv lub lig 50s. Nws hloov tawm hais tias zaj dab neeg, uas yog txuam nrog compilers thiab programming lus mus rov qab ntau tshaj rau decades. Txawm tias tej loj lub sij hawm, qhov no sib ntawm computer science nyob rau hauv txhua rooj plaub yuav tsis muab suav hais tias tawm ntawm hnub los yog tswm. On qhov tsis tooj, nrog rau cov zaj uas lub sij hawm, nrog rau cov tshwm sim los ntawm tshiab industries thiab cov kev pab raws qib uas computers siv, muaj yog ib tug yuav tsum tau tsim tshiab, ntau tus neeg siv-phooj ywg programming lus. Raws li, rau cov lus uas yuav tsum tau compilers. Qhov rais, Linux, MacOS - nws muaj nws tus kheej tsim rau txhua tus platform.

hauv paus ntsiab lus ntawm cov lag luam

Lub qhov code sau los ntawm tus tsim tawm ntawm ib tug high-theem cov lus yog hloov dua siab tshiab rau hauv qhov kev pab cuam ntawm ib tug tshwj xeeb tshuab hom lus. Cov uas ua code yog hu ua ib tug executable kev pab cuam. Nws yuav tsum tau ntsia thiab khiav rau tej computer, tsis ua tej yam ntau kev hloov.

Tej yam yooj yim, tiam sis nyuaj

Feeb ntau, compilers nyob rau hauv computer science yog ib tug ntawm cov yooj yim tej yam nyob rau hauv ntau nrog cov kev khiav hauj lwm systems thiab databases. Yuav ua li cas yog ib tug compiler? Nws yog nyob rau hauv ib lub hauv paus ntawm lub computer science.

Los ntawm lwm taw tes ntawm view, heev lub npe ntawm cov creation ntawm xws cov kev pab cuam yuav ib tug loj tus naj npawb ntawm theoretical thiab hauj yam hais txog lub cajmeem. Muaj ntau developers ntseeg tias lub ntsiab lus yog feem ntau cov feem ntau txaus nyiam nyob rau hauv tag nrho cov ntawm science. Thaum lub programmer muaj ib qhov kev pab cuam uas daws tej teeb meem, nws tau sau nws nyob rau hauv ib tug yam lus. Thaum lub sij hawm txoj kev loj hlob, nws hais lus nyob rau hauv cov nqe lus uas yog nyob ze rau lub caij nyoog cheeb tsam uas peb muaj. Lub computer tsis to taub dab tsi nws qhia rau cov neeg. Nws yog tau paub xwb nyob rau hauv ib tug yooj yim haum tej yam, uas muaj xws li cov xov tooj thiab cov tsiaj ntawm tes thiab sau, ruaj khov thiab ib ntus cim xeeb. Yuav ua li cas yog ib tug compiler? Qhov no yog ib qhov kev pab cuam uas nws ua hauj lwm - txhais lus lub tswv yim nyob ze rau qhov kev kawm cheeb tsam tsim tawm nyob rau hauv lub ntsiab hais tias yog muaj peev xwm mus muab lub computer.

Qhov no yog cov kev sib tw muab kev koom tes nyob rau hauv lub Java compiler los yog lwm yam hom lus programming. Txhua tshwm sim ntawm ib tug tshiab lus muaj yog ib tug yuav tsum tau hloov lub code sau rau ntawm nws, nyob rau hauv daim ntawv hais tias cov computer muaj peev xwm to taub. Txwv tsis pub, nws tsis tau. Tom qab tag nrho, muaj ib txwm lub semantic kis ntawm lub tswv yim ntawm tib neeg thiab computer. Nws yog los mus kov yeej nws thiab yog lub cajmeem lus compilers.

Teeb meem nyob rau hauv kev ua

Lub creators ntawm cov kev pab cuam lub ntsej muag ib tug ntau yam ntawm cov teeb meem. Qhov no scientific teeb meem uas yog txuam nrog rau qhov tseeb kuas ntawm lub tswv yim ntawm daim ntawv thov no. Qhov no engineering thiab kev siv technology tshiab teeb meem hais txog qhov kev siv ntawm no zaub.

tsim compiler ua hauj lwm muaj ib tug plurality ntawm txawv subtasks. Qhov no yog ib tug yooj yim, tab sis heev exciting kev lag luam, uas mob siab lawv lub neej kom ntau programmers. Thiab tsis txhob khuv xim.

Chav kawm ntawv thiab compiler

Tej zaum, muaj coob tus tau hnov ntawm hom lus xws li C thiab C ++. Tom qab tag nrho, lawv yog ib tug ntawm cov feem ntau nrov thiab heev. Qhov no yog ib tug heev loj programming lus, muaj hwj chim loj lub tswv yim uas yog ib qho yooj yim los qhia lub tswvyim ntawm daim ntawv thov chaw, nyob rau hauv uas lub developers ua hauj lwm. Piv txwv li, yog muaj lub tswvyim ntawm cov chav kawm ntawv thiab kev khiav dej num. Lawv yog cov tseem ceeb rau ntau yam lus, tab sis rau C ++ yog tshwj xeeb tshaj yog cov yam ntxwv.

Programmer yooj yim npaum li mus ua ib tug qauv uas muaj kev pab los ntawm tej tswv yim. Compiler C rau lub qhov rais los yog lwm yam kev khiav hauj lwm qhov system yuav pab tau tso saib cov high-theem yam nyob rau hauv daim ntawv hais tias cov computer to taub. Tsuas yog ces thaum ntawd nws yuav muaj peev xwm muab rau lawv.

Tej computer, tsis muaj teeb meem li cas haib thiab complex nws yog tej nuj nqis, ua hauj lwm nyob rau hauv ib tug heev yooj yim tswvyim. Tab sis lub tswv yim ntawm cov chav kawm ntawv yog ib qhov nyuaj, vim hais tias nrog nws yooj yim heev mus tso saib ib tug ntau ntawm tej yam uas los ntawm lub neej tiag tiag. Lub compiler converts tus complex cov ntsiab nyob rau hauv txheej thaum ub.

Tsim compiler li ua hauj lwm

Nyob rau hauv xyoo tsis ntev los, muaj ib tug ib txwm, thaum muaj loj tuam txhab, muaj feem xyuam rau cov lus qhia technology, ua nws tus kheej programming lus, uas ces txav mus rau sab masses ntawm developers.

Ntawm cov hoob kawm, rau txhua hom lus yuav tsum tau ib tug compiler. Thiab lub ruaj, raws li ib tug txoj cai, muab lawv nrog tongues. Tab sis muaj tseem yog ib tug loj tus naj npawb ntawm cov neeg sab nraud cov tsim tau thiab tuam txhab uas muag uas yog ib tug vim los yog lwm xav kom muaj lawv tus kheej compilers rau lus los yog lawv tsim tshiab lus thiab yog li, compilers rau lawv. Peb yuav confidently hais tias tus kws khomob tshwjxeeb uas tau mob siab rau nws tus kheej rau daim teb no, yeej tsis nyob twj ywm tsis ua hauj lwm.

Yog li ntawd, tam sim no nws yuav tsum muaj tseeb li cas lub compiler. Qhov no yog ib qhov kev pab cuam-tshuab txhais lus ntawm tus tsim tawm thiab cov computer, tsis muaj uas nws yog nyob rau hauv lub teb ntawm lub computer science nyob qhov twg.
