I roto i te hōtaka, he mea nui ngā pūkenga e kore anake te reo, engari ano hoki i te māramatanga o te mea te kawenga mō te aha. Ko e tika ana hoki te taea o angitu reira kapa, me i roto i te tuhinga e kitea e koe i roto i te mea i te taiao kaiwhakahaere, he aha te hiahiatia reira, he aha e nga āhuatanga. Ka hoki ki reira kia kōrero i roto i ngā whānui whakawhiti me te waehere wana, me hoki nei te tono ai.

He aha te mea te kaiwhakahaere herenga?

Na (ranei, i ētahi wā, he ako peka herenga) huaina ko te hoahoa reo hōtaka. E whakarato ana mahi o te rōpū i whakaritea ranei. Ko he taea tenei anake, no te te huru kitea o te pono o te tetahi kīanga arorau ranei tohutohu riro i te kaiwhakamahi (taputapu kaiwhakahaere) i roto i te whakatinanatanga.

whakaahuatanga General o te tono

whakamahia tauākī here te ka te raveraa i te waiho i etahi huinga o whakahau (whakahau iti), tei runga i ranei reira ko ki te mahi i te āhuatanga whakatau ranei. E taea hoki te whakamahi i te reira ki te tirohanga ki te pekapeka. Ko tetahi o toru whakaaro taketake, e kua whakamahia i roto i te hōtaka hanganga.

tauākī peka here

Tuatahi kia digress o te moka, me te mahara peita rawa rongonui Vasnetsov Victor Mikhailovich, "Knight i nga Crossroads", tuhituhia i roto i te 1878. faataa te reira i te hero e tu ana i te pekanga o te ara, me te whakatau i te wahi ki te haere. Waihoki, mahi te kaiwhakahaere te huru. Na, ki te ka manako te kaiaka te tuku ki te haere i roto i te kotahi aronga, engari ka haere ia ki runga ki te peka kotahi. Ka taea e te kōwhiringa e kotahi anake. Ki te kōrero tatou e pā ana ki te operator herenga, ka mahi i te reira anake, no te tona faaiteraa arorau he "pono". Te nuinga o ngā reo hōtaka ki te tautapa i whakamahia e te reira i te kupu matua, ki te. Pea te wā hanga, ka takina kotahi huru tuatahi, na tetahi, ka he tuatoru, he hauwhā, a na i runga i. Kia titiro a ki tenei i roto i te taipitopito atu. He aha e nga momo rerekē o ngā tauākī herenga? e toru katoa o ratou:

1. tauākī Herenga, i roto i nei i reira ko te kotahi anake manga. titiro reira (Pine) e whai ake: Ki te reira e whakamana i nga tikanga e tika ana i te mutunga kapa. Tātaitia te rorohiko te motokā, ahakoa te uara arorau o te tohu o te pono. Ki te ko te taua ki te hunga o te tahi atu wahi o te hōtaka te huru, haamata te reira ki te mahia waehere noa te mutunga kupu matua. I roto i te assembler he wātea anake ki te kaihātepe tenei puka o te mahi. Kia hoki kia te reira i taua e i roto i te mutunga i reira ka waiho he tetahi kupu matua, a ka hiahia koe ki te kia tupato e kore ki te huanga tetahi anō.
2. tauākī Herenga, ai nga manga e rua nei. titiro reira e whai ake: Ki te te huru i homai ka command1 command2 atu mutunga. Whakamahia tenei hangä hōtaka i roto i te wā i reira he mea tika i ai kua whakamana tika tetahi o nga kapa. Na reira, ki te ko te huru pono, na te wahi tuatahi o te waehere - ki te kahore te tuarua. I roto i ētahi wā, e hiahiatia ana he otinga taua te.
3. operator Herenga ki te maha o ngā āhuatanga. titiro reira e whai ake:
   ki te te huru tuatahi ka aha ki te mahi i
   atu ki te ki te kore e te huru tuatahi pai, tirohia te whai ake ka aha ki te mahi i
   atu, ki te tirohia i te tetahi tikanga katoa e tetahi Na te aha ki te mahi i
   atu, ki te kahore he tika e kore kōwhiringa i te runga ake, ka e rere te whakahau mutunga

Ka rite ki a koutou e taea te kite, whakamahi te operator herenga he hoahoa rerekē. Ratou whakatinanatanga e wahi raupapa. e kore te mea e āhuatanga taea (i technique noa), i roto i nei e timata te mahi waehere i te mutunga - tonu i te timatanga.

Tauira "Pascal"

Ki te mārama me pēhea te mahi i te reira, whakaaro tatou ki te whakaaro i te hi'oraa o tetahi o nga reo hōtaka tino rongonui. tauākī Herenga i roto i te "Pascal" taea e ohie matatini ranei. Ko te momo tuatahi - he momo o tohu =, <,>, me te rite. He tauākī here matatini i roto i Pascal taea te tango i te puka e whai ake nei:

ki te te> = y
ka
Op: = Sqr (ay)
atu
tuhituhi (He uara muhu);

He aha te mea he pana?

He aha te mea he pana? Āhuatanga o tona hoahoa ko e kua reira i te iti rawa e rua peka. Otiia anake e taea te mahi ia tetahi, whakatakotoria i mua tawhā e kua computed kīanga matua. A paraparau o te rerekē ki te tohutohu mua kia utu koutou whakarongo ki te meka e kore e te kaupapa hoki he uara Boolean, me te katoa, me te te momo e taea te hoatu ki a ia. taea hoki te te kawea te reira i roto i roto i te tahi mau reo hōtaka, whakaritea ki nga aho kuputuhi.

History o te whanaketanga

Tuatahi whakamahia e te rōpū, e tohu ana i te whakawhitinga o te tūtohu tatau. kī reira faaiteraa, mahi e rua rite te kaikōwhiri, e hoki he tōpū, me te huinga o tohutohu whakawhitinga. Kei te mahi ana Whakahaua, te uara motuhake tatau, whakamahia nei te rite he tau tapanga i roto i te rārangi katoa o whakahau hoki i reira te mea he pokarekarenga me te whakarongo o te mīhini.

Ka taea te kite i whakaaro rite i roto i te reo hōtaka pērā i "Basic" me "Fortran". E kore e taea e tatou te mea e he tino ratou i roto i o te rā, no te mea noa nei e taea te whakamanamana ratou tino tōtika nui, ki te kōrero tatou i roto i te whānui e pā ana ki hōtaka. tauākī Herenga whakamahia e te i roto i ngā reo hou, ko te hanganga matatini ake, e pä mahi. Haere hoki ki te takenga mai o tenei tūemi, e hiahia ana ahau ki te tāpiri i taua mo te faaotiraa o te manga e tika ana e kore he e tika ana ki te raupapa tukanga, me te whakatairite i te hua ki te faaiteraa o te tahi atu uara. haere noa i runga i te lekooti i roto i te ngohi mahara o ngā tohutohu peka herekore, i roto i nei kei tō wāhitau. A, no te he tohu tika e te tatau noa te mōhiohio e tika ana. Na riro te tere o te hōtaka motuhake o te maha o ngā tūtohu.

I roto i te reo hōtaka hou, e whānui nei whakamahia i te kau, whakawhiti taea hoki te hangaia te operator rite te tepu whakawhitinga tënei o nga kapa, e kawe i te kaupapa o te aro i runga i nga mongamonga tika o te waehere, kahore āhuatanga rerekē. Me pēhea e tu ratou mo? Ko te reo hōtaka taumata-tiketike, i nuinga o te wā, te whakamahi i te ingoa take, swithc e rua ranei.

Āhuatanga tātai kīanga Boolean

He mana nui i runga i te āhua o e te hōtaka ki te tauākī herenga kia mahi i, renders whāngai i roto i ia take i te tätaitanga arorau o kīanga herenga. E rua ngā rautaki matua.

1. Whakaoti tātaitanga. tātai tatou tawhā katoa ki te uara whakaratohia, a ka I.
2. tātaitanga oti. Motuhake whakaaro katoa kōwhiringa. Ki te aro mātai ana te faaiteraa ki "pono", ka tinihanga te kōwhiringa i muri. E ohipa te reira i roto i te take o RĀNEI.

mutunga

ngā herenga He hoahoa rawa hāneanea ki hōtaka. Ki te to ratou awhina, ko reira taea ki te whakatinana ngāwari whakaaro uaua, kahore he ki te whakaaro o te tangata.
