A Uhlobo olulungisiweyo - uluhlu-liyajikeleza

Ukufunda iziseko iinkqubo, okokuqala (okanye yesibini) badwelisi benkqubo elizayo uqhelene ingcamango "uluhlu-liyajikeleza." NjengoPascal, njengokuba nezinye iilwimi, ivumela ukuba ukusebenza loo nesakhiwo sedata. Kungekudala emva kukho imfuneko yokugcina ecwangciselweyo nayiphi na. Kwiimeko ezininzi, le uluhlu izinto ziphantsi uhlobo olufanayo. Umzekelo, uluhlu lwe iqela yoqeqesho ukuba ngokobungaphi bamalungu-25, nganye variable lohlobo lwamagama uzibambileyo igama kunye negama lomfundi.

Le nto ivumele ukuba bayile-liyajikeleza uluhlu e NjengoPascal, nto leyo iseti oda izinto ezifanayo. It linokubhekisela naliphi na ilungu ngolandelelwano enjalo usebenzisa ID enye efanayo isalathiso - emininzi iza kwanelaukukhetha ilizwe. Ngoko ke, ezi kwimiboniso kuthiwa liyajikeleza-.

Ababaliweyo izinto ngokulandelelana luqala kwenye, ngamanye i element wokuqala inani lezibuko 1, nto leyo kakhulu ubhalo. Noko ke, ukuba kuyimfuneko, uluhlu salathisi kuba engenasizathu ngokupheleleyo, imfuno engundoqo zichazwe njengezalathiso eyenziwa okanye integers okanye abalinganiswa (naluphi na uhlobo order).

Cinga izenzo imifuziselo a uluhlu-liyajikeleza:

1) Inkcazelo uluhlu, apho n - inani izinto ngokulandelelana, mas - uhlobo zimise uluhlu-liyajikeleza na integers 5, A - uhlobo mas variable, ngamanye ezahlukeneyo uhlobo olunye-mbini uluhlu lwe integers 5

2) izakhi ngokulandelelana negalelo lebhodi enezitshixo

3) Isiphumo ngokulandelelana iielementi kwiskrini

4) Ukugcwalisa ngokulandelelana ngokusebenzisa umbane wenani elijikelezayo

5) inguqu (ukulungisa) isiqalelo uluhlu ngasinye, ngamanye ukutshintsha ixabiso layo (umzekelo unciphiso onamacala isiqalelo ngasinye uluhlu 6)

6) Ukubekwa isixa izinto sequence S eziguquguqukayo - sum of izinto

7) Quantification lweziqalelo uluhlu ukwanelisa imeko ethile (umzekelo eqingqa linani lweziqalelo, kukho inani elikhulu 4), apho k - inani izinto ezinjalo

8) Ukubekwa le extremum (ubuninzi okanye ubuncinane i element uluhlu), apha min - ixabiso ubuncinane phakathi izinto uluhlu, k - inani ngokokuma (index) yeyona nto incinane uluhlu

Njengoko usazi, kuba zonke izinto, nakuzo izinto ezibhaliweyo kule program var icandelo UPascal lwenkqubo, inani elithile bytes kwimemori lwabelwe xa le nkqubo iqala. Oku kumiselwa uhlobo bume, umzekelo, i-Uphawu byte mnye, uhlobo udibaniso - bytes ezimbini, udidi real - bytes ezine. Ngoko ke, xa isici uluhlu ayikho elikhulu, inkqubo ayidingi isixa esikhulu RAM. Kungenjalo, uhlelo kuya kufuneka ukuba ufumane ezinye iindlela ukulungiselela uluhlu, umzekelo, xa ifayile okanye imfumba kunye ekhomba.
