Tau txais cov ntaub ntawv hom yog cov uas tau txhais nyob rau hauv cov nqe lus ntawm lwm yam hom ntaub ntawv , npe base hom . Tau txais hom tej zaum yuav muaj cov cwj pwm, thiab tej zaum yuav muaj cov ntsiab lus lossis cov ntsiab lus sib xyaw. Piv txwv ntawm tau txais hom tuaj yeem muaj cov qauv zoo XML uas siv tau raws li lawv cov ntaub ntawv hom txhais. Tej zaum lawv yog ua -in los yog user- muab tau.
Ib yam li ntawd, koj tuaj yeem nug, hom ntaub ntawv muab tau yog dab tsi?
Tau txais cov ntaub ntawv hom yog kev sib sau ua ke ntawm qhov tseem ceeb hom ntaub ntawv . tus cwj pwm, integer, ntab, thiab void yog qhov tseem ceeb hom ntaub ntawv . Pointers, arrays, structures thiab unions yog muab tau cov ntaub ntawv hom . Cov cim yog siv rau cov cim.
Qhov thib ob, koj txhais li cas los ntawm cov ntaub ntawv muab los ntawm hom C? Cov hom ntaub ntawv uas yog muab los los ntawm qhov tseem ceeb cov ntaub ntawv hom yog hu ua muab tau cov ntaub ntawv hom . Muaj nuj nqi, arrays, thiab pointers yog muab tau cov ntaub ntawv hom hauv C programming lus. Piv txwv li, ib qho array yog muab tau cov ntaub ntawv hom vim nws muaj qhov zoo sib xws hom ntawm qhov tseem ceeb hom ntaub ntawv thiab ua raws li tus tshiab hom ntaub ntawv rau C.
Ntawm no, dab tsi yog tsim nyob rau hauv datatype?
ib qho yooj yim hom yog a hom ntaub ntawv muab los ntawm ib tug programming lus raws li ib tug yooj yim tsev thaiv. Cov lus feem ntau tso cai rau kev sib xyaw ua ke hom ua recursively tsim pib ntawm qhov pib hom . a ua -hauv hom yog a hom ntaub ntawv rau qhov programming lus muab ua - nyob rau hauv kev txhawb nqa.
Dab tsi yog qhov txawv ntawm hom ntaub ntawv qub thiab cov ntaub ntawv muab tau los?
Cov ntaub ntawv tseem ceeb tseem hu ua keeb kwm hom ntaub ntawv. Muab los datatypes yog tsim los ntawm cov ntaub ntawv tseem ceeb. Qee cov ntaub ntawv tseem ceeb yog int, char, ntab, void thiab lwm yam. Muab los datatypes yog arrays, qauv, pointers thiab lwm yam.
