Vector occupies ntau ntau nco nyob rau hauv pauv rau lub peev xwm los tswj cia thiab loj hlob dynamically whereas Arrays yog lub cim xeeb zoo cov ntaub ntawv qauv. Vector yog muab tau los ntawm Sau uas muaj ntau hom ntaub ntawv generic whereas Array yog ruaj thiab khaws cov ntaub ntawv muaj zog ntau hom.

Ib yam li ntawd, ib qho vector txawv ntawm ib qho array li cas?

- A vector yog dynamic array , nws qhov loj tuaj yeem nce ntxiv, qhov twg yog qhov array qhov loj me yuav hloov tsis tau. - Reserve qhov chaw tuaj yeem muab rau vector ,qha as arrays ua tsis tau. - A vector yog ib hoob uas yog ib tug array tsis yog. - Vectors tuaj yeem khaws txhua yam khoom, qhov twg raws li ib qho array tuaj yeem khaws cov txiaj ntsig homogeneous nkaus xwb.

Ib yam li ntawd, vector puas yog array C ++? Vector hauv C++ STL. Vectors zoo ib yam li dynamic arrays nrog lub peev xwm los resize nws tus kheej tau txais thaum ib lub caij yog ntxig los yog tshem tawm, nrog rau lawv cov cia tau tuav cia los ntawm lub thawv. Vector cov ntsiab lus tau muab tso rau hauv qhov sib txuas cia kom lawv tuaj yeem nkag mus thiab hla siv iterators.

Tsis tas li ntawd, qhov txawv ntawm daim ntawv thiab vector yog dab tsi?

Ob leeg vector thiab lis yog cov ntim khoom sib txuas ntawm C++ Standard Template Library. Sau npe khaws cov ntsiab lus ntawm qhov chaw nco tsis sib thooj xws li nws sab hauv siv ob npaug txuas lis i.e. Vim li cas, vector khaws cov khoom ntawm qhov chaw nco sib txuas zoo li ib qho array i.e.

Dab tsi yog array thiab vector hauv Java?

Qhov sib txawv tseem ceeb ntawm Arrays thiab Vectors hauv Java yog tias Vectors yog dynamically faib. Lawv tsis tau tshaj tawm tias muaj hom kev hloov pauv; xwb, txhua tus Vector muaj cov npe dynamic ntawm kev xa mus rau lwm yam khoom. Thaum a Vector yog instantiated, nws tshaj tawm ib yam khoom array ntawm qhov loj pibCapacity.
