Wakavanzwa pasi pebumbiro remitemo, mutauro unopera simba, uchishuva kudzidzwa.
Nezvekunyora uku, mubvunzo wekuti "programming mutauro wekutanga kudzidza" unodzosera 517 miriyoni mitsva yekutsvaga. Imwe neimwe yemasaiti aya inorumbidza mumwe mutauro chaiwo, uye 90% yavo inozopedzisira yakurudzira Python kana JavaScript.
Pasina imwezve ado, ndinoda kuenda pane rekodhi ndichiti ese aya 517 miriyoni mawebhusaiti haana kunaka uye kuti mutauro waunofanirwa kudzidza kutanga ndewe. fundamental logic.
Kungoziva macode hakuna kukwana. Musika uyu wakazadzwa nevakapedza kudzidza kuzvikoro uye makosi zvekuti chinzvimbo chejunior chakatomira kuvapo*. Kuti ubudirire munyika yanhasi, iwe unofanirwa kukodha uye kuve nepamusoro-soro kufunga kune musoro.

Chidzidzo changu chekutanga chesainzi yekombuta
Kuratidzwa kwangu kwekutanga kusayenzi yekombuta yaive sarudzo yandakatora mugiredhi regumi. Pazuva rokutanga chairo, ndichipinda mukirasi, ndakafara kuona pamberi pangu nhamba huru yemabhakiti eaizikirimu nemitoo yakasiyana-siyana. Mushure mekunge munhu wese agara, mudzidzisi akazivisa:
“Nhasi ticharavira maaizikirimu ega ega. Asi nechimiro chimwe chete: iwe unofanirwa kuita runyoro rwemirayiridzo chaiyo yekugadzirira dessert, uye ini ndichaitevera. "
"Hapana dambudziko," ndakafunga, "chidzidzo ichi hachizotora nguva refu." Mukati meminiti imwe chete kana zvakadaro ndakanga ndanyora pasi resipi yakakwana yeaizi cream yezviroto zvangu:
- Nyora uye uise zvipunu zvitatu zve raspberry ice cream mundiro
- Vhura muto wechokoreti uye uwedzere mashupuni maviri mundiro imwechete
- Wedzera whipped cream mundiro
- Zvisasa zvose netsvimbo yehuga uye uise cherry pamusoro
Mudzidzisi wangu—“kombiyuta” iri mudimikira rakanaka iroro—akaita zvokunyomba, kuita sezvandakanga ndisati ndamboona. Akatanga kukwenya ice cream bucket nechikapu asina kana kubata chivharo chacho.
"Zvakanaka, asi unofanira kutanga wavhura!" - Ndakadanidzira, ndichiedza kuwana kurapwa nekukurumidza sezvinobvira.
“Hauna kunyora izvi mumirairo, uye ini handina kukwanisa kukugadzirira ice cream. ZVINOTEVERA!"
Ngatikurumidzei kuedza #2
- Vhura raspberry ice cream nekubvisa chivharo
- Nyora uye uise zvipunu zvitatu zve raspberry ice cream mundiro
- Vhura muto wechokoreti uye uwedzere mashupuni maviri mundiro imwechete
- Wedzera whipped cream mundiro
- Zvisasa zvose netsvimbo yehuga uye uise cherry pamusoro
Zvakanaka, ikozvino hapafanirwe kuve nematambudziko. Zvingoitika, ndakaita shuwa kuti zvese zvinongedzo pakugadzira yangu yekubika shasha yakavhurika.
Mudzidzisi akabvisa chivharo, akakweva ndokuisa zvikopu zvitatu zveaizikirimu mundiro. “Pakupedzisira, aizikirimu yangu yakanaka yakatanga kuitika!” Akabva avhura muto wechocolate ndokuisa zvipunu zviviri mundiro. Haana "kuwedzera chokoreti muto kubva pamaspuni maviri" - usafunge kudaro - iye, hongu, akaisa zvipunu ivo pachavo mundiro. Hapana muto mavari. Zvakare, handina kunetseka kunyora zvese pasi chaizvo. Mushure mekunge zvimwe zvaitwa mumweya mumwechete, ndakagamuchira mbiya yeaizikirimu uye maspuni maviri, asingaonekwe pasi pegungwa rekamuki. Pamusoro paive netsvimbo yetsvigiri.
Zvinoita sekuti panguva ino zvakazondijekera: komputa inonzwisisika mune vacuum. Haazivi nezvemamiriro ezvinhu akapoteredza uye haaiti fungidziro. Anoita mirairo yakanyatsogadzirwa uye anoitevera izwi neshoko.
Mhedzisiro yangu yekupedzisira yaive mhedzisiro yenguva refu asi yakakosha yekuyedza uye zvikanganiso:
- Kana usati watoita kudaro, vhura imwe neimwe yemapakeji anotevera: raspberry ice cream, chokoreti muto, kamu cream, shuga tsvimbo.
- Bvisa mbiya woiisa pamberi pako
- Tora ice cream scoop woisa zvipunu zvitatu zve raspberry ice cream chimwe nechimwe mundiro. Isa ice cream scoop zvakare panzvimbo.
- Tora chirongo chechokoreti muto, tora muto uye udururire zviri mupunu mundiro. Dzokorora nzira yekuchera uye yekudira imwezve nguva. Isa chipunu nechirongo zvakare panzvimbo.
- Tora pasuru yeyakarohwa cream yakatarisa pasi uye, uchiibata pamusoro pendiro, uidururire pamusoro peaizikirimu kwemasekonzi matatu, wozodzosera pasuru yacho kunzvimbo yayo.
- Tora chirongo chetsvimbo yeshuga, udira matanda makumi mana mundiro uye udzorere chirongo.
- Tora imwe cherry kubva mundiro ye cherries uye uiise pamusoro pe ice cream.
- Ipa mudzidzi ndiro ine aizikirimu yapera uye chipunu.
Pfungwa yekupedzisira yaive yakakosha, nekuti pasina iyo, nguva yekupedzisira mudzidzisi akangotanga kudya ice cream yangu.
Asi iyi ndiyo programming. Kunetsekana kwekugadzira yakangwarira seti yemirairo yekombuta. Chaizvoizvo, izvi ndizvo izvo mutauro wega wega wepurogiramu unouya pasi - kunyora mirairo.
