I c ulimi lokwakha (si)

I ulimi C Programming (kufanele ithi "B") lingachazwa ngokuthi enemisebenzi, engabizi, neqoqo egcwele opharetha, nge yesimanje isakhiwo idatha kanye flow control. Lokhu akukwazi ngokuthi "okukhulu" ulimi nolimi, futhi akusho ukuthi angasho ukuthi "izinga okusezingeni eliphezulu ulimi", yena ayidalwanga yimuphi umsebenzi othize, kunalokho, yona wazama ukwenza ngempumelelo kakhulu kunoma uluphi uhlelo lokusebenza. Lokhu Fusion ezithakazelisayo imibono linamathele C ulimi lokwakha izinhlelo kuye kwenza kwaba lula kakhulu futhi iyashelela okwesikhathi nezindaba ezahlukahlukene kunamanye, mhlawumbe ngisho izilimi okuthuthukile.

Ukuxhumana "C" OS "le Unix" liseduze kakhulu, njengoba lolu limi savela kanye "le Unix" nokunye kwe-software ebhalwe lesi simiso. Ngesikhathi esifanayo, ngezinye izikhathi ibizwa ngokuthi ulimi izinhlelo zokuhlela, njengoba kunenkolelo ukuthi ngosizo lula ukwakha olusebenzisayo, eqinisweni, sibhale kanye ke -word processing, egciniwe ngokucubungula idatha yohlelo futhi umdlalo.

C - eliphansi ulimi lokwakha izinhlelo, kodwa ungacabangi ukuthi kukubi, eqinisweni, wamane usebenza izinto efanayo njalo sisebenzela kunoma iyiphi ikhompyutha kwezimpawu, izinombolo namakheli. Kulokhu, zonke izinto ehlangana, uma kuqhathaniswa noma sisuswe ngu imisebenzi evamile okunengqondo arithmetic, i-computer evamile.

Nakuba ekusebenteni ngetintfo imisebenzi eyinkimbinkimbi ayabaluleka kuyinsakavukela emhlabeni esephepheni futhi ukushumeka zonke izilimi izinhlelo yesimanje, C, ngokungafani abanye, angeke sisebenze izinto ezifana yezinhlamvu, uhlu, amalungu afanayo noma usethe. It has no analogue imisebenzi PL / 1 ku amayunithi wezinhlamvu wonke futhi afanayo.

Nge imemori lusebenzisa isitaki and definition kwezibalo, nezinye izici inkumbulo yokusebenza kungelona, ngeke ukuthole "kweqembu» (Enqwabeni), noma "udoti", njengoba ungenza, Pascal noma Algol 68.

Futhi ngisho izindlela eziyisisekelo kakhulu-I / O, ulimi C alinikezi, opharetha Ukuzifundela Nokubhala, ngeke ukuthole kuwo, njengoba azikho imisebenzi esakhelwe kohlelo ifayela. ukusebenza ephezulu ezingeni okunjalo inikezwa ngokusebenzisa umtapo isixhumanisi.

Futhi C ulimi lokwakha ngeke senqabe ukusebenza uma udinga multiprogramming, ukuvumelanisa, imisebenzi okufanayo, njll Lunikeza amathuba kuphela umsebenzi elula neqhubekayo, isici yakhe iwukuthi: kungenxa yemijikelezo, amasheke, yokwenza iqembu, futhi subprograms.

Othile ingase ikumangaze ukuncishana izimali ezinjalo olunikezwa program ( "Kungani mina kufanele ukubiza umsebenzi njalo ngidinga ukuqhathanisa ambalwa imigqa!"), Kodwa ngakolunye uhlangothi, yingenxa izinhlelo ukonga ezinjalo abhalwe C, ukuthola inzuzo yangempela isivinini.

Ngakolunye uhlangothi, inani elincane lama-opharetha kunciphisa isikhathi ngokwengqondo adingeka ekufundeni kwabo zabo, futhi une anele amakhasi ambalwa ukuchaza kubo bonke. Futhi njengoba umkhuba sibonisa, yesakhi ne "C" - iyithuluzi compact ukuthi ilula ngokwanele ukubhala. Uma sisebenzisa amathuluzi yesimanje, umhlanganisi singesomkhiqizo ikhompyutha entsha uzolunga nje kwezinyanga ezimbalwa, naphezu kweqiniso lokuthi u-80% ikhodi uyofana izinguqulo ezandulele ikhodi. Ngenxa izici ezinjalo yakhe, C ulimi lokwakha izinhlelo ubhekwa mobile kakhulu. Yebo, futhi ukusebenza yayo wukuthi ukubhala assembler iyiphi izinhlelo okuyizona ezibalulekile ukusebenza, njengoba babevame ukwenza ngaphambi, kumane akwenzi mqondo. Isibonelo esihle kunazo zonke lokhu "Unix" OS uqobo, u-90% okulotshiwe "C", futhi isofthiwe isicelo ngoba, cishe ngokuphelele adalwe program eminingi ngolimi olufanayo emangalisayo okwamanje kubhekwe ukuba inombolo eyodwa ulimi lokwakha emhlabeni.
