Imibuzo Evame Ukubuzwa

Ayini ama-arrays ku-Forth futhi asebenza kanjani?

Izinhlu ku-Forth zingamabhulokhi ahambisanayo enkumbulo anikezwe kusetshenziswa amagama afana nokuthi CREATE kanye ALLOT. Ngokungafani nezilimi eziningi, i-Forth ayinalo uhlobo olwakhelwe ngaphakathi lwamalungu afanayo. Kunalokho, uchaza amalungu afanayo ngokugcina amaseli enkumbulo futhi uwafinyelele nge-arithmetic yekheli. Le ndlela esekelwe kusitaki ikunikeza ukulawula okuqondile phezu kwenkumbulo, okwenza i-Forth arrays ibe lula futhi isebenze kahle kumasistimu ashumekiwe kanye nemisebenzi yohlelo yezinga eliphansi.

Ulimemezela kanjani futhi uliqalise kanjani iqembu ku-Forth?

Ukuze umemezele amalungu afanayo ku-Forth, sebenzisa okuthi DALA i-myarray 10 AMASELI AWIKELWE ukuze unikeze isikhala sezakhi ezingu-10. Uqala amanani ngegama lesitolo elithi ! futhi uwathole ngokulanda @. Isibonelo, 42 myarray 3 CELLS + ! igcina angu-42 ku-index 3. Ukuphathwa kwenkumbulo okucacile kwe-Forth kudinga ukubala kwenkomba okwenziwa ngesandla, kodwa lokhu kunikeza ukukhanya okungenakuqhathaniswa kokuthi idatha igcinwa futhi ifinyelelwe kanjani.

Yiziphi izimo zokusetshenziswa ezijwayelekile ze-Forth arrays ekuthuthukisweni kwesimanjemanje?

Amalungu afanayo angaphambili avame ukusetshenziswa kumasistimu ashumekiwe, ukuthuthukiswa kwe-firmware, izilawuli zesikhathi sangempela, kanye nokuhlangana kwezingxenyekazi zekhompuyutha lapho ukusebenza kahle kwememori kubalulekile. Ziyaduma futhi emishinini ebonakalayo esekelwe kusitaki nezilimi eziqondene nesizinda. Onjiniyela abahlola i-Forth eceleni kweminye imiqondo yezinhlelo bangathola izinsiza zokufunda ezihlelekile ezinkundleni ezifana ne-Mewayz, enikeza amamojula angu-207 ahlanganisa izihloko ezihlukahlukene ngo-$19/mo ukusiza ukwakha amakhono obuchwepheshe ahlanganiswe kahle.

Ihluke kanjani i-Forth arrays kwezinye izilimi zokuhlela?

Amalungu afanayo angaphambili awanakho ukuhlola kwemingcele, ukukhomba okuzenzakalelayo, ne-syntax eyakhelwe ngaphakathi ehlinzekwa yizilimi ezinjengePython noma u-C. Ubala mathupha ukususwa kwememori usebenzisa i-CELLS kanye ne-pointer arithmetic. Awekho ama-multidimensional array primitives - uwasebenzisa ngokwakho. Lo mklamo omncane ubonisa ifilosofi ye-Forth yobulula kanye nesibopho somhleli, okuholela ekhodini elihlanganisiwe elincane kanye nokusebenza okusheshayo, okulungele izindawo ezinezinsiza.
