Cov cai hauv paus rau npe arrays yog raws li nram no:

  • Hom ntaub ntawv tuaj yeem yog cov ntaub ntawv siv tau xws li int, ntab, char qauv lossis union.
  • Lub npe ib array yuav tsum ua raws kev cai npe ntawm variables.
  • qhov loj ntawm cov array yuav tsum yog xoom los yog tus lej zoo tas li..

Ntxiv mus, yuav ua li cas hloov pauv npe?

Cov cai rau npe hloov pauv:

  1. Txhua lub npe sib txawv yuav tsum pib nrog ib tsab ntawv ntawm cov tsiaj ntawv lossis tus. underscore(_).
  2. Tom qab thawj tsab ntawv pib, cov npe sib txawv tuaj yeem muaj cov tsiaj ntawv thiab cov lej.
  3. Cov tsiaj ntawv loj yog qhov txawv ntawm cov tsiaj ntawv me.
  4. Koj tsis tuaj yeem siv C ++ lo lus tseem ceeb (cov lus tshwj tseg) ua lub npe sib txawv.

Ib tug kuj yuav nug, muaj pes tsawg lub ntsiab nyob rau hauv ib array? Hauv ib array uas muaj 5 cov ntsiab lus , thawj keeb yog 0 thiab qhov kawg yog 4.

Ib yam li ntawd, tib neeg nug, ua li cas koj tshaj tawm ib qho array hauv C ++?

Ib yam tshaj tawm rau ib array hauv C++ yog: hom npe [Elements]; qhov twg hom yog hom siv tau (xws li int, ntab), lub npe yog tus cim siv tau thiab cov ntsiab lus teb (uas yog ib txwm nyob rau hauv square brackets ), qhia qhov ntev ntawm qhov array nyob rau hauv cov nqe lus ntawm tus naj npawb ntawm cov khoom.

Yuav ua li cas koj ntxiv rau ib qho array?

Txoj kev thawb() ntxiv cov khoom tshiab rau qhov kawg ntawm ib qho array, thiab rov qab qhov ntev tshiab

  1. Nco tseg: Cov khoom tshiab yuav muab ntxiv rau qhov kawg ntawm qhov array.
  2. Nco tseg: Txoj kev no hloov qhov ntev ntawm cov array.
  3. Tswv yim: Txhawm rau ntxiv cov khoom thaum pib ntawm ib qho array, siv txoj kev unshift().
