Jagged array yog array ntawm arrays xws li cov tswv cuab arrays tuaj yeem sib txawv ntau qhov sib txawv, piv txwv li, peb tuaj yeem tsim 2-D array tab sis nrog tus lej sib txawv ntawm txhua kab. kab. Cov hom arrays no tseem hu ua Jagged arrays.
Dab tsi yog jagged array piav nrog piv txwv?
Jagged array yog ib qho array ntawm array xws li cov tswv cuab arrays tuaj yeem muaj ntau qhov sib txawv. Hauv lwm lo lus, qhov ntev ntawm txhua qhov array index tuaj yeem sib txawv. Cov ntsiab lus ntawm Jagged Array yog hom siv thiab pib ua rau null los ntawm lub neej ntawd. Jagged Array kuj tuaj yeem sib xyaw nrog ntau qhov sib txawv.
Puas jagged array tso cai rau hauv C?
Cov jagged arrays muaj nyob rau hauv c++/c tab sis cov syntax yog qhov nyuaj heev thiab koj yuav tsum ua ntau yam. Muaj ob hom jagged arrays hauv c ++. 1) STATIC JAGGED ARRAY (A 2d array uas qhov loj me yuav yog tus lej tas mus li thiab yuav muaj cov kab sib txawv ntawm txhua kab).
Kev siv jagged array yog dab tsi?
Jagged arrays yog ib hom tshwj xeeb ntawm arrays uas tuaj yeem siv khaws cov kab ntawm cov ntaub ntawv sib txawv los txhim kho kev ua haujlwm thaum ua haujlwm nrog ntau qhov arrays. Ib qho array tuaj yeem txhais tau tias yog qhov sib sau ua ke ntawm cov ntsiab lus ntawm tib hom ntaub ntawv. Cov ntsiab lus ntawm ib qho array yog khaws cia hauv qhov chaw nco sib txuas…
Qhov txawv ntawm 2D array thiab jagged array yog dab tsi?
Qhov no yog array uas khaws cov txiaj ntsig ntawm cov kab thiab kab. Qhov no kuj yog 2 D array tab sis nyob rau hauv cov ntaub ntawv ntawm 2D array tag nrho cov kab yuav tsum muaj tib tus naj npawb ntawm kab. Whereas nce ntawm jagged array kab size nws txawv ntawm kab mus rau kab. i.e. txhua kab yuav muaj cov kab sib txawv.

Dab tsi piv piv txwv hauv geometry?
Ib qho piv txwv rau nqe lus lej yog ib qho piv txwv uas txaus siab rau nqe lus cov xwm txheej tab sis tsis ua rau nqe lus xaus. Kev txheeb xyuas qhov piv txwv yog ib txoj hauv kev los qhia tias cov lus qhia lej yog cuav. Dab tsi yog qhov piv txwv hauv qhov piv txwv geometry?
