He aha e nga momo raraunga i roto i Pascal?

A, no te papatono i roto i Pascal (Pascal) kia tīpakohia momo o te hōtaka Pascal raraunga. Ko te rorohiko nui ki te mahino e i roto i te tikanga ki te whakahaere i tona wāhi hōtaka ki te rokiroki i nga kapa e kore anake tohaina i roto i te mahara, ko te raraunga i runga i nei mahi enei whakahau.

E wehea momo raraunga katoa i roto i Pascal ki e rua ngā rōpū: ohie, me te hanganga. Hoki ia momo o te raraunga i homai te he maha etahi o bytes. Hoki ngā momo ohie e: ngā momo tau tōpū (paita, tau tōpū, me ētahi atu), momo Material (tūturu, kotahi, me ētahi atu), Boolean (boolean,), momo pūāhua (char), tatau me te momo wā. He momo raupapa katoa o ratou, anake te momo tūturu me e te āhuatanga i roto i taua whai ratou he huinga iti o ngā uara whakahau. Hei tauira, he tāupe he paita momo, e taea te tango uara mai i 0 ki te 255 urutomo. Taua momo raraunga i roto i Pascal tukua ki te tono i te mahi Pred (Tātaitia te uara o mua) me Succ (computes uara muri), iti (vychislyaetet momo uara iti), me te High (Tātaitia te momo uara nui), Ord (tohutoro Tātaitia te uara o te tau tāupe nāianei).

Tetahi wahi rite te uara momo ohie e kotahi anake maramara, i.e. kotahi tau tōpū, he tau hautanga he tohu ranei. Ngā Tāupe whai momo raraunga ohie, me whakaahuatia Pascal i roto i te wāhanga Var (poto o taurangi -. Taurangi).

Te tāupe i roto i te hōtaka i roto i Pascal whakaaro ki te kia tino tohua, ki te te mea he ingoa (ID), te momo me te uara tuatahi. Ko te ingoa o te tāupe whakamahia ki te kōrero ki reira e tetahi kaiwhakahaere. Ko te momo raraunga āta te kanohi whānui (e ai tango uara tāupe), te ngā mahi i roto i nei kia whai wāhi ai reira, te nui o te mahara e hiahiatia ana mō te rokiroki i te tāupe i roto i te mahara. Na reira, ki te whakaoti i te raruraru kia ahu ki te whakaiti i te maha o ngā taurangi me te kōwhiringa kouma o momo.

momo hanganga e he huinga whakahau o ngā taurangi o ngā momo ohie. Ko ētahi o ēnei: ngohi (ngohi), huinga (huinga o), string (string), ngā kōnae (kōnae), record (record). E whakaahuatia momo raraunga hanganga i roto i Pascal i te momo wāhanga (momo wāhanga whakaahuatanga).

Ngohi - nga momo tino noa o hanganga, whakamahia te ina e hiahia ana koe ki te rokiroki me te tukatuka i te huinga whakahau o ngā taurangi o te momo kotahi (tetahi momo ohie). E kotahi-ahu, e rua-ahu, maha-ahu huānga. He tauira o te ngohi kotahi-ahu taea te mahi rite te rārangi o ngā ākonga i roto i te moheni akomanga, kōmaka i te ana'iraa piapa, te wahi ia ākonga he tau rangatū ahurei. He tauira o te ngohi e rua-ahu - te wāhi o te nohoanga i roto i te whare pikitia (takoto ia nohoanga e rua inenga - te tau rarangi me te tau nohoanga).

iti te āhuatanga o pērā ngohi disordered, me te maha o ngā huānga e ki 255. Kei te string o te huinga whakahau o pūāhua me ko reira tino rite ki te ngohi, Heoi, ka taea e te tohu anake hei āhuatanga o te aho.

Kōnae - Ko te ngohi kotahi tenei, ko te tokomaha o ngā āhuatanga i roto i reira e taea te huri i te akoranga o te hōtaka. Hopu Ko te huinga o ngā momo rerekē o te raraunga.

Na roto i te ako ki te whakamahi i ngā momo raraunga i roto i Pascal, e taea te whakatinana mahi rawa matatini, me te ngā.
