I ihluzo in the "Pascal": izici, izindlela indalo nezibonelo

Ingabe Ngidinga ihluzo uMklami? Ikakhulukazi labo abasanda kuqala ukufunda ulimi? Kufanele siqale sihlole yonke imiklamo zokubhala imisebenzi eyisisekelo kanye ezivamile futhi schedule ikhefu kamuva?

Lawa imibuzo ukubaphendula ngakho bonke abantu yena. Ngokwesibonelo, labo abafundisa ulimi sesikole, isheduli ku "Pascal" kuyindlela enhle ukuze sikhuthaze ngokwakho ukuqhuba izifundo. Ngemva kwakho konke lokhu ngesikhathi ngifuna ukubona imiphumela yakhe yokucabanga, ukubhala izinhlelo. Uma sikhuluma umfundi, bese udonsela omunye aphoyintimenti. Kunalokho, izenzo njengoba isici asizayo eyenza imikhiqizo okubhaliwe ashukumisayo ngaphezulu. Kodwa noma kunjalo, le ngxenye ulimi lokwakha Yiqiniso, kubalulekile.

Kumele kukhunjulwe ukuthi akubona bonke izimali babe ihluzo ukwesekwa. "Pascal," nayo ifakwe lesi sici, ngakho-ke kuba isakhiwo yayo ngeke echazwe esihlokweni.

I ihluzo in the "Pascal"

kufanele uqale kuphi? Ukusuka lapho, kudingeka uqonde ukuthi yini iyunithi ubuncane kwesikrini ezimeni ezahlukene kolimi "Pascal". Uma kuziwa umbhalo, bese ngakho kuyoba uphawu. Isimiso kufanele bakhetha the pixel. It has izixhumanisi ukuthi emelelwa izimpawu X, Y, no umbala (ejwayelekile - omhlophe). Ukuze uthole ikheli kwe-pixel (0, 0), kubalulekile ukubeka ekhoneni ngakwesobunxele. Kuyinto lapha siqala ukubala izixhumanisi.

I ihluzo in "Pascal ABC» icushiwe nge module ukuthi kuyadingeka ukuze ubhalise ukusetshenziswa line.

iphuzu

Njengoba isibonelo lula uzonikezwa umsebenzi okukhiphayo amaphuzu esikrinini (ngezansi).

Esikhathini Izimemezelo kwesigaba, ungabona amagama amamojuli elondolozwe ku ukusetshenziswa line. Bahlanganisa ihluzo kwimodi ohlelweni. Uma unjiniyela lihlangane isakhiwo uhlelo, angase acabange ukuthi nje udinga ukubhala eziguquguqukayo asizayo ngo var. Kodwa lesi sigaba, ihluzo e "Pascal", iyehlukahluka kancane. Ngemva izwi var ukubhala ihluzo ikhadi efakwe ku-PC yakho, abese ucacise mode esebenza kuwo. Letimphawu nguleti ezivamile. Ngemva ukuvulwa parentheses opharetha kufanele uqaphele uhlobo langempela futhi imodi. Uma umsebenzisi akazi onjani adaptha ifakiwe, kubalulekile ukuba alobe inani Uhlelo umugqa 7. Lesi sigaba, efana ihluzo in "Pascal" yakhelwe ukuze inqubo uyakwazi kuzihlonzekele ukukhomba idatha. Kubalulekile nokukhumbula ukuthi zonke adapters sinokubaluleka yabo zezinombolo ngayinye ingatholakala ngokubheka kwi-inthanethi. In the line lwesishiyagalombili kungabonwa inqubo Initgraph. Uyagijima imodi ihluzo. Inombolo yolayini 9 kanye nenombolo 10 ziyadingeka ukuze ubone uma Ukuqalisa waya ngokuzumayo ehluleka, uhlelo kuyekile ukusebenza. closegraph uvala imodi ihluzo, okukuvumela ukuba ubuyele emuva umbhalo.

Imigqa olunezinombolo 2, 3, 7-10, 17 Kudingeka sikhumbule ngoba ingasetshenziswa njengesibonisi, njengoba bonke ihluzo in "Pascal" ine jikelele isakhiwo indalo. Cabangela izici kweminye imisebenzi.

Ngaphansi umbala variable kudingeka baqonde ezahlukene imibala in the "Pascal" kukhona 15. kuphela Ngokwenza value engahleliwe, kumelwe siqonde ukuthi ithoni izokhetheka nemiyalezo. umugqa 14 ikuvumela ukudala iphuzu esikrinini. Kulesi nkinga, kuyothiwa elise lapho "iyoshiya" okungahleliwe Ukukhetha imodi.

Luhlelo umsebenzi

Kufanele kuqondwe ukuthi igrafu umsebenzi ku "Pascal" Kwakhiwani ngezigaba ezimbili. Okokuqala, udinga ukwakha isimiso izixhumanisi, bese udweba igrafu uqobo. Futhi wokuqala futhi ihlukaniswe izigaba eziningana.

Ukuze uhlelo ingekho phezulu esibukweni, kumele ucacise indawo yayo. engela Upper - (xLeft; yLeft). Lower eqoshiwe efanayo - (xRight; yRight). Ukudala Ukudidiyela-eksisi, okuyinto izibalo kukhona notation kakhulu, kumele wazi isikhungo. Futhi kwencazelo yokugcina kudingeka ukuba uqonde indlela agumenti futhi ukubaluleka umsebenzi. Khetha iphuzu oyifunayo, ungaqhubeka ukuqopha hlelo.

I ihluzo in the "Pascal" kuhilela ukusetshenziswa inqubo SetPixel, ngemva kwalokho kulandela kubakaki abonisa izixhumanisi iphuzu (x evamile futhi y) nombala (variable). A umsebenzi Line ivumela ukudweba eksisi.

Bhala uhlelo kuyadingeka ngokulandelana ezifana: lokuqala Ukudidiyela uhlelo, futhi ekugcineni udinga ukubala ukubaluleka umsebenzi futhi ukubala izixhumanisi iphuzu.

yi

Amaphuzu isiphetho esikrinini kanye ukwakhiwa igrafu umsebenzi in the "Pascal" osemqoka, ngomqondo ongokomfanekiso, zonke esigabeni isizinda. Njengoba yayazi ukubhala izinhlelo ukuqaliswa yabo, uMklami angasebenzisa ihluzo ezinguqulweni zalo ezihlukahlukene. Kuyinto nje Kuhle ukwazi le mfundiso. I ihluzo in the "Pascal" (izibonelo enikezwa esihlokweni) - umbuzo olula kakhulu futhi ezithakazelisayo.
