siab dua ntawm abstraction - txoj hauv kev saum toj kawg nkaus txhawb kev paub daws teeb meem ntawm qib ua haujlwm. Txoj hauv kev taw qhia yam khoom txhawb nqa kev paub daws teeb meem ntawm qib khoom.
Yuav ua li cas yog qhov kev xav tau?
Ib txoj haujlwm tseem ceeb npe ib nqe lus ib leeg, yog li qhov tseem ceeb yog qhov kev xav - saib cov piv txwv hauv koj phau ntawv kom paub meej. Hauv programming, abstractions tuaj yeem ua lossis rhuav tshem cov khoom tsim tau. Tias yog vim li cas ntau zaus, feem ntau siv cov haujlwm tau sau rau hauv cov tsev qiv ntawv uas tuaj yeem rov siv tau los ntawm lwm tus.
Yuav ua li cas yog ib qho ntawm cov hauv qab no siv rau abstraction?
Kev piav qhia: Classyog qhov kev xav paub tseeb vim nws muab cov qauv kev xav rau txhua yam ntawm nws cov khoom. Nws muab cov ntsiab lus ntawm cov yam ntxwv ntawm ib yam khoom.
Dab tsi yog abstraction hauv kev ua haujlwm ua haujlwm?
A programming abstraction yog ib lub tswv yim sib faib ntawm qhov peb tswj ncaj qha, thiab qhov kawg tshwm sim lossis qhov ua tiav tiag tiag… Cov lus programming yog lawv tus kheej piv txwv ntawm kev paub daws teeb meem. Ib hom lus qib siab zais kev sib dhos lossis byte code, uas nws tus kheej hides tshuab code.
Qhov twg hauv qab no yog kev ua haujlwm ntawm cov ntaub ntawv abstraction?
Qhov twg hauv qab no yog qhov ua haujlwm ntawm 'Data Abstraction'? Kev piav qhia: Ib qho tseem ceeb ntawm Object Oriented Programming yog 'Data Abstraction' uas txhais tau tias zais khoom. Complexity yog tswj los ntawm abstraction.

Kev txhawb nqa menyuam puas tuaj yeem kuaj xyuas qhov kev txhawb nqa thib ob?
Kev them nyiaj yug me nyuam dhau los yuav tsis raug tshem tawm ntawm daim tshev kev txhawb nqa thib ob. Qhov kev txhawb nqa thib ob txwv tsis pub txeeb cov tshev nyiaj rau feem ntau ntawm cov nuj nqis, suav nrog cov qiv nyiaj ntiag tug thiab tsev txhab nyiaj .
Txoj kev paub daws teeb meem puas muaj kev siv c?
Yes chav kawm paub daws teeb meem tsis tuaj yeem ua sai sai (koj yuav tsum ua kom cov chav kawm uas tau txais los ntawm koj chav kawm paub daws teeb meem), tab sis nws tuaj yeem muaj cov kev siv. Nws yog qhov zoo thiab tso cai, chav kawm paub daws teeb meem muaj tsawg kawg yog ib tus tswv cuab (txoj kev / khoom vaj khoom tsev) tsis siv kom nws tsis tuaj yeem ua sai sai .
Puas yog lwm txoj kev daws teeb meem ntawm kev tawg sab nraud?
Lwm txoj kev daws teeb meem rau sab nraud fragmentation yog tso cai qhov chaw nyob qhov chaw ntawm cov txheej txheem kom tsis sib thooj. Cov txheej txheem yog faib nrog lub cev muaj peev xwm nco thiab thaum twg tom qab muaj, nws raug xa mus rau txheej txheem .
Puas yog plaub txoj kev flashers teeb meem teeb meem?
Txhua lub tsheb tuaj nrog teeb ceeb toom teeb meem raws li cov khoom siv txheem. Kuj tseem hu ua "kev phom sij," "kev kub ceev blinkers" lossis "four-way flashers," cov teeb no pab koj cov neeg tsav tsheb pom koj thaum muaj ib yam dab tsi tsis ncaj ncees lawm ntawm koj lub tsheb, lossis thaum koj yuav tsum nres tsis tau xav txog.
Muaj pes tsawg qhov kev daws teeb meem zoo hauv kev ua haujlwm linear?
Lub hom phiaj tseem ceeb ntawm cov txheej txheem optimization yog nrhiav cov txiaj ntsig ntawm qhov sib txawv uas txo qis lossis ua kom lub hom phiaj ua haujlwm kom txaus siab rau qhov txwv. Cov txiaj ntsig no yog hu ua kev daws teeb meem zoo.
