Lipotso Tse Botsoang Hangata

Li-arrays ho Forth ke eng, 'me li sebetsa joang?

Litlhophiso ho Forth ke liboloko tsa memori tse tsamaisanang tse fanoeng ka mantsoe a kang CREATE le ALLOT. Ho fapana le lipuo tse ngata, Forth ha e na mofuta o hlophisitsoeng o kopaneng. Sebakeng seo, o hlalosa li-arrays ka ho boloka lisele tsa memori le ho li fihlella ka arithmetic ea aterese. Mokhoa ona o thehiloeng ho stack o o fa taolo e tobileng holim'a mohopolo, o etsa hore Forth arrays e be bobebe hape e sebetse hantle bakeng sa litsamaiso tse kentsoeng le mesebetsi ea maemo a tlase.

O tsebahatsa jwang le ho qala sehlopha ho Forth?

Ho phatlalatsa sehlopha ho Forth, sebelisa CREATE myarray 10 CELLS ALLOT ho fana ka sebaka bakeng sa likarolo tse 10. U qala litekanyetso ka lentsoe la lebenkele ! 'me u li fumane hape ka fetch @. Mohlala, 42 myarray 3 CELLS + ! e boloka 42 ho index 3. Taolo ea memori e hlakileng ea Forth e hloka lipalo tsa index, empa sena se fana ka ponaletso e ke keng ea lekanngoa mabapi le hore na data e bolokoa le ho fihlella joang.

Ke maemo afe a tloaelehileng a ts'ebeliso ea Forth arrays ho nts'etsopele ea sejoale-joale?

Li-arrays tsa pele li sebelisoa hangata lits'ebetsong tse kentsoeng, nts'etsopele ea firmware, balaoli ba nako ea nnete, le khokahano ea lisebelisoa moo ho sebetsa hantle ha memori ho leng bohlokoa. Li boetse li tumme mecheng e sebetsang e thehiloeng ho stack le lipuong tse ikhethileng tsa domain. Bahlahisi ba hlahlobang Forth hammoho le likhopolo tse ling tsa lenaneo ba ka fumana lisebelisoa tsa ho ithuta tse hlophisitsoeng sethaleng se kang Mewayz, e fanang ka li-module tse 207 tse buang ka lihlooho tse sa tšoaneng ho $19 / mo ho thusa ho haha ​​litsebo tsa tekheniki tse phethahetseng.

Forth arrays e fapana jwang le mefuta ya dipuo tse ding tsa mananeo?

Lihlopha tsa pele ha li na ho lekola mellwane, indexing ea othomathike, le syntax e ahelletsoeng ka har'a lipuo tse kang Python kapa C. Ka bowena u bala litheolelo tsa memori u sebelisa CELLS le lipalo tsa pointer. Ha ho li-multidimensional array primitives - u li sebelisa ka bouena. Moralo ona o bobebe o bonts'a filosofi ea Forth ea ho ba bonolo le boikarabello ba mohlophisi, e fellang ka khoutu e nyane e kopantsoeng le ts'ebetso e potlakileng, e loketseng tikoloho e haelloang ke lisebelisoa.
