Njirayi imabweretsa zitsimikizo zamakono zachitetezo ku C popanda kufunikira kulembedwanso kwathunthu m'chinenero chosungika pamtima.

Chifukwa chiyani chitetezo m'malire ndi chofunikira kwa opanga C?

C imapatsa omanga mwayi wokumbukira molunjika, womwe umapereka magwiridwe antchito koma umabweretsa zoopsa monga kusefukira kwa buffer, nsikidzi zosagwiritsa ntchito pambuyo pake, komanso kusatetezeka kwa ma code. Oyang'anira chitetezo amatsata izi panthawi yophatikiza kapena nthawi yothamanga, ndikuchepetsa kwambiri zolakwika zachitetezo. Kwa magulu omwe ali ndi ma codebase C, kutsatira chitetezo mochulukirachulukira ndikothandiza kwambiri kuposa kusamukira ku chilankhulo china kwathunthu.
