Ulwimi lokuprograma BASIC nembali yayo

History of Programming Languages uyazi imizekelo emininzi xa kukho revolution yokwenene kakhulu kweenkqubo. Imbali ulwimi BASIC senkqubo - kanye oko. Ukusuka ulwimi elincinane, ngaphantsi-ofanayo ekufundiseni, uye waba umgangatho yokwenene phantse kuzo zonke lwenkqubo iilwimi.

ulwimi BASIC lokuprograma waphuhliswa Thomas uKurtz noYohane Kenema ngo-1964 ngenjongo yokufundisa abafundi iziseko iinkqubo. Ulwimi wajika elula, ecacileyo, kunye ujongano ngokwanelisayo lula. Injongo ababhekisi phambili kwacaca: kwakufuneka ulwimi olulula lokuprograma leyo kuba zombini ezifikelelekayo. Nazi amalungiselelo ezisisiseko ngqalelo "Boyise 'of BASIC:

1) lula ukusetyenziswa;

2) Mass;

3) ulwazi;

4) Ulwimi kufuneka ixhase ubuchule umkhondo neempazamo ezichanekileyo;

5) Le ulwimi kufuneka kufuna ulwazi hardware kakhulu;

6) ulwimi lokuprograma kufuneka abe unxibelelwano phakathi umsebenzisi kunye operating system.

Ngenxa yoko, iye yasetyenziswa kwezinye amaziko amaninzi emfundo. kweminyaka 11 kamva, xa ihlabathi igcwale izigidi ulwimi olutsha microcomputer lokuprograma BASIC abanomdla Bill Gates kunye noPawulos Allen, abantu wadala Microsoft. Ngabo, ukusebenza kunye, ukuphuculwa uguqulelo lwe BASIC ngenxa yayo iikhompyutha okokuqala, nto leyo isebenze nkqu 4k of RAM (!).

Emva kwexesha elithile, oko uguqulelo yabo iye yaba ngomnye isetyenziswe qho yaye ethandwa iilwimi kweenkqubo. Ngexesha lokusekwa BASIC ulwimi lokuprograma rhoqo bazama ukuvala, abaninzi bangathanda ukufumana amaphutha ukuvala ukusetyenziswa kolwimi. Nangona kunjalo, kunye kokufika kweekhompyutha IBM, liye laba lilitye BASIC ulwimi lokuprograma engundoqo, nto leyo ijolise kwi kwabanye. Kubalulekile ukuphawula ukuba wayesele ngokuba GW-basic. Emva koko beza engundoqo kwiinqwelo evela kwinkampani Borland kunye Quick esiSiseko. Zonke iinguqulelo zaye zaphuhliswa kamva, ngokuyimfuneko ibhalwe ngendlela eya ukugcina wokuhambelana yangaphambili. Nkqu uguqulelo zakutshanje yale ulwimi lokuprograma lisebenza ndizekela kwasentloko, kunye uhlengahlengiso ezincinane.

Kwaye emva koko kwafika ixesha Microsoft. Ukuqala 90: indlela yokusebenza iifestile kuthinjwa phantse yonke imarike software, wonke umntu wavuya ukubona konke - ngaphandle badwelisi benkqubo. ubomi babo baba isihogo. Ukudala indlela, iifestile ezininzi eziqhelekileyo elula, kuyimfuneko ukuba ukubhala elwandle ikhowudi amaphepha, ukutshintsha iifonti yokubhala, yaye ekugqibeleni ukuba 'sisondele' window ezintsha. Kodwa kufuneka siqonde ukuba inzuzo enkulu kakhulu neengxaki, yaye ekugqibeleni, uguqulelo yesithathu kwinkqubo yokusebenza iye yaba umgangatho lwehlabathi le PC.

Kukho imfuneko kwi ukuguqulwa BASIC. Ngoko ke, lo ulwimi lokuprograma BASIC waziwa Microsoft Visual Basic. Malunga izicwangciso nenxa nkampani lalingekafiki ayaziwa ke loo nto, nangenxa non-iingcali ababhekisi phambili ziye kujoliswe ikakhulu ulwimi olutsha lokwakha. inkqubo senkqubo, kuphunyezwa Visual Basic, wenza kube lula ukuhambisa kude isakhiwo elinzima iifestile ukudala kwinqanaba kakuhle inkqubo, hayi ukuba inani elikhulu ulwazi. Isikhonkwane yokugqibela kule bhokisi, nto leyo phantse kungcwatywa abanye, iintlobo ezinjalo iilwimi lokuprograma kakhulu elungileyo efana Fortran kunye NjengoPascal, waye uphuhliso ntlobo zezicelo BASIC.

Okwangoku, ulwimi lokuprograma BASIC zithandwa kakhulu kangangokuba phantse yonke wenkqubo self-nokuhlonipha uyazi, kwaye bakwazi ukulisebenzisa. Kufuneka kuqatshelwe ukuba ezisetyenziswa kwizicelo ezifana ofisi Microsoft kunye Internet Explorer. Kodwa mhlawumbi omnye amasimi ezibalulekileyo isicelo, ulwimi BASIC lokuprograma, waba ukuphuhlisa kunye nokuqwalasela izicelo kwindawo .NET le. Ukongeza, uphuhliso entsha ibandla Bill Gates, Microsoft C ++ ivula kubasebenzisi uluhlu omkhulu okunokwenzeka, kwaye zonke Bulelani ukuya kooprofesa ezimbini ukusuka Dartmouth College.
