Object Oriented Programming vs Procedural Programming

Object Oriented Programming (OOP) thiab Cov Txheej Txheem Txheej Txheem yog ob qhov kev qhia ua haujlwm. Lub programming paradigm yog ib qho tseem ceeb ntawm kev siv computer programming, thiab lawv txawv ntawm txoj kev sib txawv ntawm qhov kev pab cuam tau sawv cev thiab yuav ua li cas cov kauj ruam los daws cov teeb meem raug txhais. Raws li lub npe qhia, OOP tsom rau sawv cev cov teeb meem siv cov khoom siv tiag tiag thiab lawv tus cwj pwm thaum lub sijhawm, Cov Txheej Txheem Txheej Txheem cuam tshuam nrog kev sawv cev rau cov kev daws teeb meem siv cov txheej txheem, uas yog sau cov cai uas khiav hauv ib qho kev txiav txim tshwj xeeb. Muaj cov lus programming uas txhawb nqa qhov tseem ceeb ntawm OOP (hu ua OOP hom lus), Procedural (hu ua Procedural languages) thiab ob qho tib si. Tab sis ib qho tseem ceeb uas yuav tsum nco ntsoov yog OOP thiab Txheej Txheem yog ob txoj hauv kev los sawv cev cov teeb meem kom daws tau, thiab nws tsis muaj teeb meem siv hom lus twg. Hauv lwm lo lus, OOP hom lus tuaj yeem siv rau Cov Txheej Txheem Txheej Txheem Kev Ua Haujlwm thaum cov lus txheej txheem qee zaum siv tau rau OOP, nrog rau qee qhov kev siv zog.

Procedural Programming yog ib txoj hauv kev los ntawm kev txheeb xyuas cov txheej txheem los daws qhov teeb meem thiab qhov kev txiav txim meej uas lawv yuav tsum tau ua kom ncav cuag qhov xav tau lossis lub xeev. Piv txwv li, yog tias koj xav xam qhov nyiaj hli xaus rau lub txhab nyiaj, cov kauj ruam yuav tsum tau ua raws li hauv qab no. Ua ntej, koj tau txais qhov pib tshuav ntawm tus as khauj thiab tom qab ntawd koj txo tag nrho cov nqi debit tshwm sim nyob rau lub hli. Tom qab ntawd, koj ntxiv tag nrho cov nyiaj qiv nyiaj tau tshwm sim thaum lub hli. Thaum kawg ntawm tus txheej txheem, koj yuav tau txais lub hli kawg kaw qhov nyiaj tshuav ntawm tus account. Ib qho ntawm cov ntsiab lus tseem ceeb ntawm Cov Txheej Txheem Kev Ua Haujlwm yog Kev Ua Haujlwm hu. Ib txoj haujlwm tseem hu ua subroutine, txoj hauv kev los yog ib txoj haujlwm muaj cov lus txib uas yuav tsum tau ua. Ib txoj kev tuaj yeem hu tau txhua lub sijhawm thaum lub sijhawm ua tiav los ntawm lwm cov txheej txheem lossis los ntawm nws tus kheej. Piv txwv ntawm Procedural programming languages yog C thiab Pascal.

Nyob hauv OOP, lub hom phiaj yog xav txog qhov teeb meem los daws cov ntsiab lus ntawm lub ntiaj teb tiag tiag thiab sawv cev rau qhov teeb meem ntawm cov khoom thiab lawv tus cwj pwm. Object yog cov ntaub ntawv qauv uas zoo ib yam li qee yam khoom tiag tiag. Cov khoom muaj cov ntaub ntawv teb thiab cov txheej txheem uas sawv cev rau tus cwj pwm thiab tus cwj pwm ntawm cov khoom tiag tiag. Muaj ob peb lub ntsiab lus tseem ceeb OOP xws li Data abstraction, Encapsulation, Polymorphism, Messaging, Modularity thiab Inheritance. Qee hom OOP nrov yog Java thiab C. Txawm li cas los xij, lawv tuaj yeem siv los ua Cov Txheej Txheem Txheej Txheem thiab.

Qhov sib txawv tseem ceeb ntawm OOP thiab Cov Txheej Txheem Txheej Txheem yog qhov tseem ceeb ntawm Cov Txheej Txheem Txheej Txheem yog txhawm rau txhawm rau ua haujlwm hauv kev ua haujlwm rau hauv kev sau ntawm cov hloov pauv thiab cov txheej txheem subroutines thaum, lub hom phiaj ntawm OOP yog txhawm rau txhawm rau ua haujlwm hauv lub program. cov khoom, uas encapsulate cov ntaub ntawv thiab txoj kev. Qhov sib txawv tseem ceeb tshaj plaws tuaj yeem yog thaum Procedural Programming siv cov txheej txheem los ua haujlwm ncaj qha ntawm cov ntaub ntawv cov qauv, OOP yuav ntim cov ntaub ntawv thiab cov txheej txheem ua ke kom ib qho khoom siv ua haujlwm ntawm nws tus kheej cov ntaub ntawv. Thaum nws los txog rau nomenclature, txheej txheem, module, txheej txheem hu thiab variable nyob rau hauv Procedural Programming feem ntau hu ua txoj kev, khoom, lus thiab tus cwj pwm nyob rau hauv OOP, feem.
