String tsis yog hom ntaub ntawv tseem ceeb hauv C ++. Yam tseem ceeb hauv C ++ tau muab faib ua peb pawg: ib qho, ntab taw tes, thiab tsis muaj dab tsi. Integral types Integral types Ib tus lej luv tuaj yeem sawv cev rau tus lej tag nrho uas yuav siv sijhawm tsawg dua, thaum muaj ntau yam me me, piv nrog tus lej lej ntawm tib lub tshuab. Hauv C, nws yog denoted los ntawm luv. Nws yuav tsum muaj tsawg kawg yog 16 khoom, thiab feem ntau me dua li tus qauv tus lej, tab sis qhov no tsis tas yuav tsum tau. https://en.wikipedia.org › wiki › Integer_(computer_science)
Integer (computer science) - Wikipedia
muaj peev xwm tuav tag nrho cov lej. Floating point hom muaj peev xwm txheeb xyuas qhov tseem ceeb uas yuav muaj feem feem.
Qhov twg hauv qab no tsis yog hom ntaub ntawv?
Arr tsis yog hom ntaub ntawv. Kev piav qhia ib kauj ruam dhau los: Hauv kev tshawb fawb hauv computer, Boolean cov ntaub ntawv hom yog hom ntaub ntawv uas muaj ib qho ntawm ob qhov txiaj ntsig - feem ntau yog qhov tseeb thiab tsis tseeb. Tus cwj pwm yog hom ntaub ntawv khaws cia / muab cov tsiaj ntawv thiab lwm cov cim.
Cov hom ntaub ntawv tseem ceeb yog dab tsi?
Cov ntaub ntawv tseem ceeb ntau yam yog:
- char (Character)
- int (Integer)
- float (Floating point)
- bool (Boolean)
- ob (ob npaug taw tes)
- void (valueless)
Puas yog enum cov ntaub ntawv tseem ceeb hauv C?
Feem ntau, rau cov haujlwm me me, peb siv cov ntaub ntawv tseem ceeb hauv C – int, char, ntab, thiab ob npaug. Rau ntau cov ntaub ntawv nyuaj thiab loj heev, peb siv hom derived - array, qauv, union, thiab pointer. Kev suav sau thiab tsis muaj dab tsi suav nrog enum thiab void, feem.
Dab tsi yog hom ntaub ntawv piav qhia meej?
Ib hom ntaub ntawv yog kev faib cov ntaub ntawv uas qhia tus neeg sau lossis tus neeg txhais lus li cas tus programmer npaj siab siv cov ntaub ntawv. Cov lus programming feem ntau txhawb ntau hom ntaub ntawv, suav nrog tus lej, tiag, tus cwj pwm lossis txoj hlua, thiab Boolean.

Vim li cas cov ntaub ntawv tseem ceeb tseem ceeb rau kev tswj hwm tebchaws Askiv?
Cov ntaub ntawv raug cai ntawm cov thawj coj hauv tebchaws Askiv ua haujlwm qhov tseem ceeb ntawm keeb kwm ntawm no lub sijhawm. Cov thawj coj hauv tebchaws Askiv ntseeg tias txhua qhov kev qhia, kev npaj, txoj cai, kev txiav txim siab, kev pom zoo, kev tshawb nrhiav yuav tsum tau sau kom meej.
Dab tsi yog qhov tseem ceeb thiab tsis tseem ceeb?
Qhov me dua p-tus nqi, qhov muaj zog pov thawj uas koj yuav tsum tsis lees paub qhov kev xav tsis tseeb. Ib qho p-tus nqi tsawg dua 0.05 (feem ntau ≤ 0.05) yog qhov tseem ceeb. … A p-tus nqi siab dua 0.05 (> 0.05) tsis yogqhov tseem ceeb thiab qhia cov pov thawj muaj zog rau qhov kev xav tsis zoo .
Leej twg yog numismatics yog qhov tseem ceeb ntawm cov ntaub ntawv?
Ib tug numismatist, yog li ntawd, yog tus neeg uas kawm npib thiab lwm yam nyiaj, feem ntau yog los ntawm kev tshawb fawb keeb kwm thiab keeb kwm. Npib yog ib qho ntawm cov ntaub ntawv tseem ceeb tshaj plaws uas cov kws tshawb fawb thiab keeb kwm tuaj yeem sim txhais yav dhau los .
Qhov twg hauv qab no yog siv los xyuas kom meej tias cov ntaub ntawv yog cov tsiaj ntawv?
Qhov twg hauv qab no yog siv los xyuas kom meej tias cov ntaub ntawv yog cov tsiaj ntawv? Nqe lus piav qhia - Siv qhov kev xaiv - c nrog cov khoom siv xaiv txhawm rau txheeb xyuas tias cov ntaub ntawv tau raug txheeb xyuas . Qhov twg hauv qab no yog siv rau decompressing cov ntaub ntawv?
Vim li cas qhov tseem ceeb yog qhov tseem ceeb?
Nws yuav tsum muaj lub zog lub cev thiab lub siab lub ntsws. Qhov tseem ceeb yog qhov tseem ceeb uas tso cai rau koj mus txuas ntxiv thiab ua lub neej zoo. Hauv qhov tseem ceeb, qhov tseem ceeb txhais tau hais tias muaj zog, noj qab nyob zoo, thiab muaj txiaj ntsig zoo.
