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.
