"Pascal" - he reo ... "Pascal" mō tīmata: Whakaahuatanga

I roto i te nui o te Tukutuku Ao Whānui, ka taea e kitea e koe i te rota o ngā hōtaka i roto i te reo "Pascal", engari nui atu uaua ki te feruri i roto i pehea mahi ratou, a ka kua whakaritea i runga i te aha pūtake. Kia titiro tahi o nga taketake o te hōtaka!

reo Algorithmic: ariā taketake

I roto i te kupu kīwaha whakamahi tatou i te wae taketake: te pūāhua, kupu, kīanga me ngā rerenga kōrero katoa. reo Algorithmic hoki kua he hanganga ōrite, engari e karangatia ona wāhanga rerekē. Kei te korero tatou e pā ana ki ngā hanganga taketake, kīanga me ngā tauākī. enei wae katoa hanga he hanganga aroākapa, rite i hanga te ia huānga ngā i te runga ake.

Tohu reo algorithmic - ko ngota wehewehe whakamahia mō te tuhituhi waehere.

hoahoa Basic - ko nga wae iti e whai ratou ake tikanga.

E hanga e kīanga reo Classic i te wae e rua i runga, me te whakanoho i te tikanga mō te te kimi i te uara e hiahiatia ana.

Ko te operator te kawenga mō te whakaahuatanga o te huringa tauwhāiti i te mea e tika ana mo te mahi tika o te hōtaka. He kia maha ngā, ki te tika - me te mahi i te hōtaka, he mahi uaua. I roto i taua āhuatanga, kei te ngā ratou i roto i te taua poraka pūhui ranei tauākī.

Reo "Pascal"

He he maha nui o ngā reo hōtaka. "Pascal" (mō te tīmata i reira e te tahi mau painga) ko tetahi o ratou. tito Ko tōna pū te o tau, reta, me pūāhua motuhake. Tenei ko te rārangi o ratou:

• 26 pūmatua me Latin reta pūriki ;
• ahungarua pūāhua;
• tekau mati;
• limiters;
• tohu mahi;
• specifiers;
• i whakatoea e te pūnaha (mahi) o te kupu.

Haunga nga mea timatanga i runga, no reira ki te huinga o taketake "pātea" e kore e taea te whakamahi i roto i te hanganga me te whakapuaki o waiho e tohu rua.

ngā hanganga reo Elementary

"Pascal" mō tīmata ngā aho, tau, me ngā ingoa.

Ko te tau e whakamahia ana i roto i te waehere raro arotake, kei te nuinga o te reo papatono tuhituhia i roto i te pūnaha ira. Ka taea e kia ratou e rua tūturu me katoa, i hanga kaua hoki e whakahuatia o te tekauira. Ki te he pai te maha, e taea te mahue tohu ona.

"Pascal" - ko te reo hōtaka algorithmic i ai nga aho he he raupapa o ngā pūāhua, kati i apostrophes. Ki te hiahia koe ki te whakamahi i te pakini ano, tenei tohu he utu te whakahua rua.

Ingoa - he raupapa e haamata ki te pukapuka, me te kia roto i roto i ona tau hanganga. E huaina TT tūtohu, momo, taimau, mahi, ngā tukanga, taurangi, ngā, a tae noa kōwae. Hanga pūwehe taea e koe te whakamahi i te pūāhua ahungarua. Ka taea e whai i te rota o te huru te ingoa, engari ka lau te taupatupatu anake te pūāhua tuatahi 63. "Pascal", te whākinga o e ai mea na uaua, e kore e pera whakamataku, na e kore rere ki te e wehi, me te ki te kati i te whārangi pūtirotiro!

Ka rite ki e rāhuitia te pūwehe reo i te whakamahi i nga ingoa paerewa o taimau, ngā tukanga, momo o ngā kōnae, ngā mahi, me te kīanga pūnaha.

Te whakapai ake i te kitenga o e tauturu i te āputa i te waehere, engari he mea utu te haamana'oraa e kore e taea e ratou te faaite i te ingoa me te tau i roto i te waenganui.

Wetereo reo algorithmic

Me mutu ia aho ki te irapiko i roto i te hōtaka, i tuhituhia i roto i te reo e whakaaro tatou ( "Pascal"). haapii Informatics nga tauira me ngā ākonga, a ka taea ki te matau i enei ture ratou koe!

Ko te kopipiko (;) - he tohu te whakarite, e te parau e pā ana ki te mutunga o te raina o nāianei, me te hiahia ki te neke ki te tetahi hou. Ko te kahore hoki te whakahau mahi e taea e: const, var, timata me etahi atu.

Ko te operator kati te mutunga hōtaka, na i muri i tika i te reira mua e te wāhi. I te tahi taime e taea i roto i waehere e rave rahi āpitihanga, na te timatanga me te whakamutunga o ka wehea e te kopipiko te poraka.

Hei tautapa i te uara motuhake o te tāupe te aroaro o nga i waenganui haina he tika ki te hoatu i te kopirua. Hei tauira, haere koe ki te whakaturia n = 13, me te waehere e haere ana ki te titiro rite n: = 13.

Ki te ako koe i te ture, ka taea tino hohoro koutou ako ki te tuhituhi waehere pūmanawa kahore hapa wetereo.

tauākī reo Classical "Pascal"

Programmed waehere tono heke mai auau, me te whakatinana i te reira ki tetahi mahi he taea i te tikanga o ngā huarahi rerekē. Ko te whakamahia te reo "Pascal" mo tenei whakaaro ngā ngā. Katoa o ratou, e kore e taea e matou whakaaro, na reira, ka matau tatou ki te torutoru anake.

Hei tauira, mā te tīpako i te kaiwhakahaere e taea te whiriwhiri tetahi o nga ara kē o rere te hōtaka. Tawhā i roto i tenei take ko te faaiteraa o te momo raupapa. Ko reira te mea he arai: e kore e taea e tenei kī tīpakonga no ki te aho momo tūturu ranei.

i reira ano he tauākī ohipa, here, hiato, me te kau, me te rota o te tahi atu haumi whaihua. Knowledge o anake etahi o ratou e āhei ki a koutou tuhituhi waehere ki taumahinga pai. e kore kia tukino hoki ngā, no te mea o ratou tokomaha nui hanga te hōtaka uaua ki te patuiro taupatupatu, puputu'u, me te tino uaua ki te kite tangata ke.

Ko te kaiwhakahaere taumahi

Tenei faaiteraa Ko te kopirua me haina "rite". Kei te whakamahia te reira ki te tautapa i te tāupe motuhake o te uara ngā. He mea nui ki te mahara e kia te taua i roto i te kaupapa e kore ratou e hāngai ki te katoa, me te momo tūturu, aua te momo o ngā kīanga tāupe me. Anake i roto i te āhuatanga i taua e whakatika faafariuraa.

tauākī pūhui

"Pascal" - he reo hōtaka e whakamahi ana i te raupapa o ngā tauākī hōtaka noho kopakia ana i roto i te taiapa motuhake. Ko reira e pā ana ki te hanganga hiato, timata me te mutunga o nga kupu iti. Ko te taputapu nui mo te reo algorithmic ki i te mea e taea ki te tuhituhi waehere whakamahi tikanga hanganga tenei.

kia tino rerekē ngā o te reo "Pascal", ngā i roto i te wahi o te hanganga hiato, no te mea i reira he kahore fakangatangata. kia hoki kia rerekē hohonu kōhanga.

operator Herenga reo papatono

Tenei wae whakarato te kaha ki te tirohia i roto i te wā i te huru hōtaka i tohua me te mahi i tētahi mahi i runga i te hua o tona wahi rānei. Ko te kupu, ko te whakahau here - ko tetahi o nga tikanga o te hanganga o manga i roto i te tukanga o te raveraa i tātaitanga.

Te hanganga, tauākī here ko e whai ake:

IF Na ELSE .

I roto i tenei faaiteraa atu, ka me ki te he kupu i rahuitia, te huru - te faaiteraa arorau ki te ihirangi te noho, me ngā - i tetahi whakahau whakamahia reo papatono.

Ko te hanganga o te waehere hōtaka

wāhanga Pane ngā me ngā whakamārama - he te wāhanga matua o te tono i tuhituhia i roto i te reo pērā i "Pascal" enei. hangarau Information whakahohe ai tino tūhura enei āhuatanga, me te ako e founga ki te whakamahi i tika a ratou.

te tikanga kei roto i te pane i te ingoa waehere. Hei tauira, Program MyFirst.

Ka taea e whakaahuatanga Wāhanga tikanga o whare pukapuka tūhono, kōwae, tapanga, taimau, momo, taurangi, whakaahuatanga pene o nga mahi me ngā tukanga.

Kei wāhanga whakaahuatanga o te kōwae i roto i te ingoa o whare pukapuka hono me tīmata ki te kupu rāhui whakamahi. Me waiho te reira i te tuatahi i roto i te tahi atu whakamārama katoa. kia tonu ngā ingoa Kōwae kia wehea e ngā piko.

Tetahi operator waehere e taea te hoatu te ingoa tapanga ki te kia whakahuatia i roto i te wāhanga e hāngai ana o te whakaahuatanga.

whakaahuatanga halá taea taimau i roto i te waehere i raro ki te rēhita ratou ingoa hei utu o ngā uara tau ārepa ranei.

I roto i te whakaahuatanga o te taurangi whakamahia kia ngā momo katoa kia e ka whakamahia: "var c, he, r: tau tōpū; k, l, m: char; H1, H2: pūreana;".

Kaua e wareware e "Pascal" - he reo hōtaka e titau te whakaahuatanga tuatahi obligatory o nga wae katoa whai wāhi i roto i te hōtaka.

Me mutu kuputuhi waehere ki te ira.

tauira o ngā hōtaka

"Pascal" - ko te reo māmā tenei, a ka taea e puta tika koe ki te tuhituhi waehere i muri i ako i te mōhiohio i runga ake.

Kia whakarite tatou i kawea mai kua te tono ki te mata te kīanga «Ko taku hōtaka tuatahi!»

Tauira o ngā hōtaka i runga i "Pascal" Ko te tino nui ki te matau, na tamata ki te mahi i reira tika i teie nei.

Tīmataria te
Writeln (Ko toku hōtaka tuatahi '!);
Whakamutunga.

Ko te pera ohie!

Titiro hoki waehere matatini ake, ki e taea e koe te kitea te pakiaka o te whārite pūrua. Kia whai whakaaro ki te parau tumu o te hanganga o kīanga tātai.

Te tūmanako, i pai ki a koutou i te hōtaka tauira i runga i te "Pascal".
