Uhlobo ehlelekile - afanayo eyodwa-ntathu

Ukutadisha izisekelo lwezinhlelo, yokuqala (noma yesibili) program esizayo ujwayelene welithi "afanayo eyodwa-ntathu." Pascal, njengoba nezinye izilimi, uvumela ukusebenza ezifana isakhiwo idatha. Ngokuhamba kwesikhathi kukhona isidingo isitoreji ehlelekile kwanoma iyiphi eziguquguqukayo. Ezimweni eziningi, lokhu iqoqo izakhi basonta uhlobo olufanayo. Ngokwesibonelo, uhlu iqembu ukuqeqeshwa kungenziwa yakhiwe amalungu angu-25, ngalinye elikwazi ingukungena ohlobo yezinhlamvu ebamba igama igama umfundi.

Yilokhu ivumela ukuba uqaphele umuntu ntathu afanayo e Pascal, okuyinto isethi ngaphambilini izakhi ezifanayo. Lingase libhekisele kunoma yiliphi ilungu ukulandelana enjalo usebenzisa okufanayo ID okufanayo Inkomba - nenombolo ye-sequence. Ngakho-ke, lezi afanayo abizwa ngokuthi omunye ntathu.

Sezinombolo izakhi ukulandelana ngokuvamile iqala ngesikhathi esisodwa, okungukuthi element lokuqala has a nenombolo ye-serial 1, okuyinto ngempela okunengqondo. Nokho, uma kunesidingo, uhla Inkomba kungaba ngokungenasizathu ngokuphelele, imfuneko esemqoka ngokuthi indices kwenziwe noma integers nobe balingisi (yiluphi uhlobo oda).

Cabanga ngezenzo ejwayelekile ye afanayo eyodwa-ntathu:

1) Incazelo afanayo, lapho u-n - enanini lama-elementi ngokulandelana, mas - uhlobo zimise afanayo eyodwa-ntathu of integers 5, A - uhlobo mas variable, isb elibanzi uhlobo eyodwa-ntathu afanayo 5 integers

2) izakhi ukulandelana ikhibhodi input

3) lokukhipha ukulandelana izakhi esikrinini

4) Ukugcwalisa ngekulandzelana asebentisa okungahleliwe inombolo generator

5) ukuguqulwa (ukuguqulwa) element afanayo ngamunye, isb ukushintsha inani layo (isibonelo ukuncipha ntathu ngamunye isici afanayo 6)

6) Ukunqunywa inani izakhi ukulandelana kukhona S variable - isamba izakhi

7) Quantification izakhi afanayo wanelise isimo esithile (isibonelo sokunquma enanini lama-elementi, inani elikhulu 4), lapho k - nenani izici eziningana ezinjengolwazi

8) Ukunqunywa extremum (esiphezulu noma ubuncane element afanayo), lapha imiz - ubuncane ukubaluleka phakathi izakhi afanayo, k - neenomborosikhundla (Inkomba) iyona element encane kunazo zonke afanayo

Njengoba wazi, ukuze zonke eziguquguqukayo, ezichazwe esigabeni Uhlelo Var e Pascal izinhlelo, inombolo ethile amabhayithi kwimemori lwabelwe lapho isimiso siqala. Lokhu kunqunywa uhlobo variable, isibonelo, uphawu ingenye ibhayithi, uhlobo inamba - amabhayithi ezimbili, uhlobo real - amabhayithi ezine. Ngakho-ke, lapho ubukhulu ngamakhono ahlukahlukene ingenkulu, uhlelo akudingi semali RAM. Kungenjalo, uhlelo kuyodingeka uthole ezinye izindlela ukuze ihlanganise amalungu afanayo, isibonelo, ifayela noma inqwaba nge izeluleko.
