Abstraction siv kev nkag mus rau cov kev qhia tshwj xeeb Kev nkag mus rau cov cim tshwj xeeb yog lub hauv paus tseem ceeb ntawm kev siv abstraction hauv C ++. Peb tuaj yeem siv kev nkag mus tus qauv tshwj xeeb los tswj kev txwv rau cov tub kawmPiv txwv li: Cov tswv cuab tau tshaj tawm tias pej xeem hauv chav kawm, tuaj yeem nkag mus tau los ntawm txhua qhov chaw hauv qhov program.
Yuav ua li cas yog abstraction tiav?
Cov ntaub ntawv abstraction yog ib txoj hauv kev uas cov ntsiab lus tseem ceeb tau tshwm sim rau cov neeg siv thiab cov ntsiab lus tsis tseem ceeb tau muab zais. Hauv Java, kev paub daws teeb meem yog ua tiav los ntawm siv cov ntsiab lus paub daws teeb meem rau cov chav kawm thiab kev sib cuam tshuamHauv cov chav kawm paub daws teeb meem, peb tuaj yeem muaj txoj hauv kev paub daws teeb meem nrog rau cov qauv tsim.
Puas C muaj abstraction?
Cov ntsiav tuaj yeem hu cov haujlwm no rau txhua tus tsav tsheb I/O yam tsis tas yuav tsum paub dab tsi txog lub cuab yeej. Nov yog ib qho piv txwv ntawm abstraction hauv C. Saib kab lus no kom nyeem ntxiv txog qhov piv txwv tshwj xeeb no. Lwm daim ntawv ntawm cov ntaub ntawv abstraction yog opaque pointers.
Dab tsi yog cov ntaub ntawv abstraction hauv C?
Data Abstraction hauv C ++ Cov Ntaub Ntawv Abstraction yog txheej txheem ntawm kev muab cov ntsiab lus tseem ceeb rau lub ntiaj teb sab nraud thiab zais cov ntsiab lus sab hauv, piv txwv li, sawv cev tsuas yog cov ntsiab lus tseem ceeb hauv qhov kev zov me nyuam.
Yuav ua li cas abstraction ua tiav hauv C?
Abstraction tuaj yeem ua tiav siv cov chav kawm paub daws teeb meem hauv C.
Dab tsi yog abstraction hauv C?
- Koj tsis tuaj yeem tsim qhov piv txwv ntawm chav kawm paub daws teeb meem.
- Koj tsis tuaj yeem tshaj tawm txoj kev paub daws teeb meem sab nraud ntawm chav kawm paub daws teeb meem.
- Thaum ib chav tau tshaj tawm tias kaw, nws tsis tuaj yeem tau txais qub txeeg qub teg, cov chav kawm paub daws teeb meem tsis tuaj yeem tshaj tawm tau kaw.
