Ndedzipi dziri muForth uye dzinoshanda sei?

Arrays in Forth mabhuroko endangariro anosanganisirwa akagoverwa uchishandisa mazwi akaita seCREATE uye ALLOT. Kusiyana nemitauro mizhinji, Forth haina mhando yakavakirwa-mukati. Panzvimbo iyoyo, iwe unotsanangura arrays nekuchengetedza ndangariro maseru uye nekuawana kuburikidza nekero arithmetic. Iyi stack-based approach inokupa kutonga kwakananga pamusoro pendangariro, zvichiita kuti Forth arrays ireruke uye inonyatsoshanda kune akamisikidzwa masisitimu uye yakaderera-level programming mabasa.

Unozivisa nekutanga sei rondedzero muForth?

Kuzivisa array muForth, shandisa CREATE myarray 10 CELLS ALLOT kugovera nzvimbo yezvinhu gumi. Unotanga nezwi rechitoro ! wozvitora nekutora @. Semuyenzaniso, 42 myarray 3 CELLS + ! inochengeta 42 pa index 3. Forth's explicice memory management inoda ma manual index calculation, asi izvi zvinopa pachena kusinga enzaniswe kuti data rinochengetwa uye rinowanikwa sei.

Ndedzipi makesi ekushandiswa akajairika eForth arrays mukuvandudzwa kwemazuva ano?

Yemberi arrays anowanzo shandiswa mumasisitimu akaiswa, kusimudzira firmware, real-time controllers, uye hardware interfacing uko kushanda kwendangariro kwakakosha. Ivo zvakare vane mukurumbira mune stack-based virtual muchina uye domain-yakananga mitauro. Vagadziri vanoongorora Forth pamwe nemamwe maprogramme concepts vanogona kuwana zviwanikwa zvekudzidza zvakarongwa pamapuratifomu seMewayz, iyo inopa mazana maviri nenomwe modules inovhara misoro yakasiyana pa$19/mo kuti ibatsire kuvaka hunyanzvi hwekuita hwakakwana.

Ko Forth arrays inosiyana sei nearrays mune mimwe mitauro yekuronga?

Zvirongwa zvekumberi hazvina miganhu yekutarisa, indekisi ye otomatiki, uye sintakisi yakavakirwa-mukati inopihwa nemitauro yakaita sePython kana C. Iwe unoverengera mamemory offset uchishandisa CELLS uye pointer arithmetic. Iko hakuna multidimensional array primitives - unozviita iwe pachako. Iyi minimalist dhizaini inoratidza huzivi hwaForth hwekureruka uye basa remugadziri, zvichikonzera diki kodhi yakaunganidzwa uye nekukurumidza kuuraya, yakanakira nharaunda-ane zviwanikwa.
