Ukuhlelwa Kwegeyimu Kwabaqalayo kuyisihloko sokuqala ochungechungeni. Kuyo ngiqala ukubhekana nezisekelo zezinhlelo. Ngiyazi ukuthi kuzoba wumgwaqo omude nonzima, yingakho ngiqala ekuqaleni. I-athikili yokuqala ikhuluma ngezinto eziyisisekelo zolimi lokuhlela lwe-C Ingenye yezinto eziyisisekelo zokuhlela. Ngisebenzisa uhlelo ngezinyathelo zami zokuqala zokuhlela Ikhodi :: Amabhulokhi.
Luyini ngempela uhlelo?
Ngesihloko sohlelo lomdlalo lwabaqalayo, ngithanda ukuqala ngesihloko sohlelo. Uhlelo lusebenzisa amaziro kanye nalawo ukuxhumana nekhompyutha. Ukuze ubhale uhlelo udinga ulimi lokuhlela.
Ukuze uqale, udinga uhlelo ukuze ubhale ikhodi yakho. I-Visual Studio ilungele lokhu. Ukhetha Okusha -> Iphrojekthi -> Uhlelo Lokusebenza Lwekhonsoli
Ikhodi yakho iya endaweni emakiwe:
Ekugcineni kubukeka kanjena:
Izinhlelo zegeyimu yabaqalayo - Sawubona Mhlaba
Ngizoqala ngokuhlela igeyimu yabaqalayo ngokukhetha iphrojekthi entsha. Kuyiphrojekthi yokuhlela yakudala ethi "Sawubona Umhlaba". Lolu hlelo lukhona kuphela ukuze lubonise umusho olunikezwe lona futhi luyiphrojekthi ekahle uma kuziwa ezinhlelweni zegeyimu zabaqalayo.
Uhlelo lubukeka kanjena:
#hlanganisa
#hlanganisa
unogada ()
{
printf(“Sawubona mhlaba! Unjani?”);
buyisela i-0;
}
Ngizama ukwehlukanisa izingxenye zohlelo.
Amafayela amabili okuqala abizwa ngamafayela kanhlokweni.
#hlanganisa
#hlanganisa
Faka nezimele ezithi “faka”. Ngaphandle kwale migqa emibili, imisebenzi ethile ku-C ayikwazi ukusetshenziswa. Ngekhodi: Amabhulokhi ajwayelekile uma kudingeka uhlelo olusha. I-“stdio.h” iwumtapo wezincwadi lapho imiyalo yesihloko ngasinye ibhalwe khona.
I-“int main()” wuhlelo oluyinhloko.
i-int imele inani eliphelele. Kusho uhlobo lwedatha yenani eliphelele. Kuhlelo lwama-32-bit, izinombolo ezisuka ku- −2.147.483.648 kuya ku- 2.147.483.647 zingamelwa kulo.
"okuyinhloko" ithi okulandelayo kuwumsebenzi oyinhloko wohlelo.
Abakaki abasontekile baqukethe ikhodi yohlelo.
printf -> imele okukhiphayo
"" -> iqukethe umbhalo okufanele uhlelo luwukhiphe
Isitatimende ngasinye silandelwa semicolon; kuvaliwe. Uma i-semicolon ingavali umyalo, kubonakala iphutha.
buyela i-0
Lapho usuqedile ukubhala uhlelo lwakho, iya kokwakhela uhlelo ukuze umhlanganisi ahlole amaphutha wohlelo.
Bese ungaqala uhlelo usebenzisa okuthi “Run” futhi lizokukhombisa umbhalo owufakile.
Uma ufaka \n phambi kombhalo, uzodluliselwa emugqeni olandelayo njengokunqamuka komugqa. Ngemuva kwalokho kufanele uhambe uyokwakha futhi bese ugijima. Uhlelo futhi lunikeza inketho ethi "Yakha futhi Uqhube".
Uhlelo oluphambili luphakathi kwabakaki abakhiqizi.
#hlanganisa
#hlanganisa
unogada ()
{
printf(“Sawubona mhlaba! \n Kunjani?”);
buyisela i-0;
}
uma ufaka i- \ t, kunezelwa izikhala eziningi phakathi kwemisho efanele.
#hlanganisa
#hlanganisa
unogada ()
{
printf(“Sawubona mhlaba! \n Unjani?\t Uyaphila?”);
buyisela i-0;
}
Yini umhlanganisi?
Umhlanganisi uqinisekisa ukuthi imiyalo engena umdidiyeli iguqulwa ibe nguziro kanye neminye. Ngalokhu kuguqulwa, i-PC iqonda imiyalelo. Ulimi lwe-PC luwulimi olunambambili, oluhlanganisa kuphela u-XNUMX no-XNUMX. Uma imiyalo ingaguqulelwa olimini kanambambili, i-PC ayazi ukuthi yenzeni. Idinga futhi uhlelo lomthombo: “Umthombo”.
Umhlanganisi uhlukanisa amagama nezinhlamvu kuhlelo lomthombo ekuhlaziyweni kwe-lexical. Uma kunezinhlamvu ezingalungile kuhlelo, umhlanganisi uzibona njengamaphutha. Umhlanganisi usebenzisa ukuhlaziywa kwe-syntactic ukubheka ukuthi ngabe imiyalo ilungile yini. Ukuhlaziywa kwe-semantic kunquma ukuthi ngabe uhlelo lomthombo lunengqondo yini futhi luyafundeka kwi-PC. Uma kunephutha ezinhlelweni, umhlanganisi ukhipha inqubo bese ekhombisa umyalezo wephutha.
Yiziphi izinhlobo zedatha ezikhona ku-C?
Ukuze ukwazi ukusebenzisa ulimi lohlelo lwe-C, izinhlobo ezahlukahlukene zedatha ziyasetshenziswa. Izinhlobo zedatha zinika amandla ukuthi kwenziwe imisebenzi ethile yohlelo. Ububanzi bamanani bunikezwa uhlobo lwedatha ngalunye. Ukuze ukwazi ukucubungula idatha nhlobo, izinhlobo zedatha ziyadingeka njengesisekelo.
Izinhlobo zedatha eyisisekelo
Lezi zinhlobo zedatha zisiza izinhlelo ukucubungula izinombolo nezinhlamvu. Ngaphambi kokuthi kukhethwe uhlobo lwedatha lohlelo, kufanele kucace ukuthi yini okucutshungulwayo: Izinhlamvu, umbhalo, izinombolo noma izinombolo zephoyinti zingasetshenziswa.
Izinombolo eziphelele
Uhlobo lwedatha "inamba" lugcina izinombolo kuphela. Uhlobo lwedatha yoMlingiswa lugcina kuphela izinhlamvu nezinhlamvu. Izinombolo zingaba ezincane, eziphakathi noma ezinkulu.
Ububanzi bamanani bunikezwa uhlobo lwedatha ngalunye ngesikhathi sohlelo. Lokhu kuchaza ukuthi yiluphi uhlobo lwedatha olungagcina ukuthi yiziphi izinombolo.
uhlamvu
Abalingiswa bangabonakala ngesikhundla inqola ukusindisa. Leli gama luhlobo lwedatha futhi lukhombisa ukuthi lulandelwa uhlamvu. Izincazelo zabalingiswa ziku Ithebula le-ASCII ebanjiwe. Isethwa ngokuzenzakalelayo. Uhlamvu ngalunye lunikezwe ikhodi. I-ASCII i-American Standard Code for Information Interchange. Uhlamvu olufana no-“A” umlingiswa. Ukuze ukwazi ukubonisa lo mlingiswa ohlelweni, udinga ikhodi 65, ongayifunda etafuleni.
imibono
Amazwana aphinde asize ezinhlelweni zegeyimu kwabaqalayo ukuchaza izigaba zohlelo eziyinkimbinkimbi. Abanakwa umdidiyeli. Zenzelwe abantu kuphela.
Ukuphawula komugqa owodwa
Ukuphawula komugqa owodwa kumakwe ngokusikwa okuphindwe kabili:
#include int main () {
// Nakhu ukuphawula:
printf(“Sawubona Umhlaba\n”);
buyisela i-0;
}
Ukuphawula kwemigqa eminingi
Asetshenziselwa izincazelo ezinde kukhodi yomthombo. Amabhulokhi amakhulu kukhodi yomthombo athola imibono emikhulu. Azicutshungulwa ngumhlanganisi.
Ukuphawula kwemigqa eminingi kwethulwa nge / * futhi kugcina ngo * /
Umhlanganisi uziba noma yini ephakathi.
/*
I-multiline iqala lapha
amazwana
*/
#hlanganisa
int main () {
/*
printf (“Sawubona”)
printf(“Umhlaba”\n“);
*/
// Umbhalo ukhishwa lapha:
printf(“Sawubona\n”);
buyisela i-0;
]
I-Visual Studio ilungele ukuqaliswa kwamakhodi.
Nakhu kuya Ukuhlelwa kwegeyimu ku-Unity
Kuthunyelwe ekuqaleni ngo-2018-08-08 17:17:00.
