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.
