Los ntawm Wikipedia: Hauv C programming lus, zoo li qub yog siv nrog lub ntiaj teb sib txawv thiab cov haujlwm los teeb tsa lawv cov peev txheej rau cov ntaub ntawv uas muaj. Hauv zos variables, zoo li qub yog siv los khaws qhov sib txawv nyob rau hauv lub statically faib lub cim xeeb es tsis txhob ntawm cov cia li faib lub cim xeeb.

Tom qab ntawd, vim li cas peb thiaj siv rov qab 0 hauv C?

Hauv C thiab C ++ cov haujlwm tseem ceeb yog hom int thiab yog li nws yuav tsum rov qab los tus nqi integer. Cov rov qab los tus nqi ntawm lub luag haujlwm tseem ceeb yog suav tias yog "Tshem Tawm" ntawm daim ntawv thov. Nyob rau hauv feem ntau operating systems rov 0 yog qhov kev vam meej zoo li hais tias "Qhov kev zov me nyuam ua haujlwm zoo". Thaum kawg ntawm lub luag haujlwm tseem ceeb.

Yuav ua li cas koj tshaj tawm ib array hauv C?

Txhawm rau tshaj tawm ib qho array, koj yuav tsum qhia meej:
