Video: Koj yuav ua li cas tshem vector ua haujlwm hauv C ++?

meej () muaj nuj nqi yog siv rau tshem tawm tag nrho cov ntsiab lus ntawm cov vector thawv, yog li ua nws loj 0.
Algorithm
- Khiav ib lub voj mus txog qhov loj ntawm qhov vector .
- Xyuas seb lub ntsiab ntawm txhua txoj hauj lwm yog faib los ntawm 2, yog tias muaj, tshem tawm lub ntsiab thiab decrement iterator.
- Sau qhov kawg vector .
Dhau li ntawd, koj puas xav rho tawm vectors C ++?
Koj tuaj yeem ua tus vector sab hauv StringContainer cov tswv cuab pej xeem thiab cuam tshuam nrog nws ncaj qha, tab sis nws tseem zoo dua tsim los ua kom nws ntiag tug lossis tiv thaiv thiab ntxiv qee cov tswv cuab kev ua haujlwm los tswj txoj hlua * vector . Yog li koj lub ntsiab C++ qhov kev pab cuam yuav tsum yeej tsis pom tus tshiab los yog rho tawm nyob qhov twg.
Tsis tas li ntawd, lub sij hawm vector yog dab tsi? Hauv kev kawm tob, txhua yam yog vectorized, los yog hu ua kev xav vector los yog lus vector , thiab ces lub complex geometry transformation yog ua nyob rau hauv lub cov duab . Hauv Lucene's JAVA Doc, lus vector txhais tau tias "A lus vector yog ib daim ntawv teev cov ntaub ntawv nqe lus thiab lawv cov naj npawb ntawm qhov tshwm sim hauv daim ntawv ntawd."
Yog li ntawd, dab tsi yog vector hauv C ++?
Vectors hauv C ++ yog cov ntim khoom sib txuas uas sawv cev rau cov arrays uas tuaj yeem hloov qhov loj. Lawv siv cov chaw khaws cia sib txuas rau lawv cov ntsiab lus, uas txhais tau hais tias lawv cov ntsiab lus tseem tuaj yeem nkag mus siv offsets ntawm cov taw qhia tsis tu ncua rau nws cov ntsiab lus, thiab zoo li hauv cov arrays.
Koj tsim ib lub vector li cas?
Export cov duab ua ib cov ntaub ntawv vector
- Nyem rau ntawm Cov Ntaub Ntawv lossis Illustrator ntawv qhia zaub mov thiab xaiv "Txuag Raws li."
- Txuag ib daim ntawv ua ib qho. ua file.
- Xaiv ib hom vector los ntawm "Save As Type" ntawv qhia zaub mov. Cov no suav nrog SVG (webpage) thiab PDF (print).
- Tsis txhob khaws cov ntaub ntawv li-p.webp" />
