Qhov Tseem Ceeb Qhov Sib Txawv - Cov Neeg Sawv Cev vs Cov Txheej Txheem hauv C
C yog hom lus programming tsim los ntawm Microsoft. Nws txhawb Structured Programming thiab Object-Oriented Programming. Cov neeg sawv cev thiab cov xwm txheej yog siv rau kev ua haujlwm uas tau tsav los ntawm C. Ib tug delegate yog hom-zoo pointer rau ib txoj kev. Nyob rau hauv ib daim ntawv thov nrog Graphical User Interface (GUI), muaj cov nyees khawm thiab lwm yam. Thaum ib lub pob nyem, qee yam kev ua tshwm sim. Cov kev ua ntawd hu ua tej xwm txheej. Piv txwv li, refreshing ib nplooj ntawv web yuav ua rau cov nplooj ntawv load tshwm sim. Kab lus no tham txog qhov sib txawv ntawm cov neeg sawv cev thiab cov xwm txheej hauv C. Qhov sib txawv tseem ceeb ntawm tus neeg sawv cev thiab cov xwm txheej hauv Cyog tias tus neeg sawv cev yog qhov siv rau ib txoj hauv kev thaum muaj kev tshwm sim cuam tshuam nrog tus tuav kev tshwm sim uas siv tus delegate. Thaum muaj xwm txheej tshwm sim, nws xa ib lub teeb liab rau tus neeg sawv cev. Tom qab ntawd tus delegate executs lub luag haujlwm. Li no, tag nrho cov txheej xwm yog nyob ntawm tus delegates.
Dab tsi yog Delegates hauv C?
Delegates hauv C zoo ib yam li hu rov qab ua haujlwm hauv lwm yam lus programming xws li JavaScript. Cov haujlwm hu rov qab raug muab rau ntawm lub sijhawm ua haujlwm. Lawv muab kev ua haujlwm uas tuaj yeem hloov mus rau hauv thiab tawm raws li qhov xav tau. Tib yam tuaj yeem siv tau siv cov neeg sawv cev hauv C. Cov delegates hauv C decouples tus hu thiab hu ua haujlwm. Yog li ntawd, nws txo qhov hnyav coupling.
