Nooca A habeysan - soo diyaariyeen hal dhinac-cabbir ah

Waxbarashada aasaasiga ah ee barnaamijyada, marka hore (ama labaad) borogaraam mustaqbalka yaqaan fikirka ah "dagaal isugu diyaariyeen ka mid waji leh." Pascal, sida luqado kale, u ogolaanaya in ay la shaqeeyaan sida dhismeedka data. Fogaato ama waxaa loo baahan yahay kaydinta dhisan oo doorsoomayaasha kasta. Xaaladaha intooda badan, set this ee xubno ka tirsan tahay nooca la mid ah. Tusaale ahaan, liiska kooxda tababarka ka kooban karo 25 xubnood, kuwaasoo mid walba uu yahay variable ka mid ah string nooca in uu haystaa magaca iyo magaca ardayga.

Tani waa waxa u ogolaanaya in ay ogaadaan hal-cabbir ah isugu Pascal, taas oo ah set ah amar ku bixiyay in xubno la mid ah. Waxa uu tilmaami karaa xubin kasta oo isku xigxiga sida isticmaalaya ID la mid ah oo la mid ah index - tirada isku xigxiga. Sidaa darteed, arrays kuwaas waxaa loo yaqaan mid waji leh.

Waa tiradoodii iyo xubno isku xigxiga badanaa bilaabataa mid, i.e. element ugu horeysay ee uu leeyahay tiro ka mid ah serial 1, taas oo waa wax macquul ah. Si kastaba ha ahaatee, haddii loo baahdo, kala duwan oo index wuxuu noqon karaa mid si buuxda loo aabo yeelin, shuruudaha ugu muhiimsan ee sida indices sameeyaa ama abyoonayaasha ama characters (nooc si).

Tixgeli falalka caadiga ah ee la isugu soo hal-cabbir ah:

1) Description of isugu soo diyaariyeen, halkaas oo n - tiro xubno isku xig xiga, mas - nooca loo diyaariyey dagaal isugu diyaariyeen hal-cabbir ah abyoonayaasha 5, A - nooca mas variable, i.e. variable ah nooca hal-cabbir ah isugu soo of 5 abyoonayaasha

2) xubno la isku xigxiga aqbasho keyboard

3) Output isku xigxiga ee xubno shaashadda

4) Buuxinta xigxiga la isticmaalayo matoor lambarka aan sugnay

5) Isbadal (beddelid) ee element soo diyaariyeen kasta, i.e. beddelo miraheeda (tusaale u ah hoos u waji leh ee element kasta isugu soo 6)

6) Determination of qadarka xubno isku xigxiga waa S variable - wadarta ee canaasiirta

7) Quantification xubno isugu soo dherginaya xaalad gaar ah (tusaale u ah go'aaminta tirada cunsur, tiro badan oo ah 4), halkaas oo k - tirada qaybaha sida

8) Determination of extremum ah (ugu badnaan ama ugu yaraan element safi), halkan min - qiimaha ugu yar ee ka mid ah xubno isugu diyaariyeen ka, k - tirada horsanaanta (index) waa element ugu yar ee isu safi

Sida aad ogtahay, waayo, doorsoomayaasha oo dhan, kuwaas oo tilmaamay in barnaamijka Var qaybta barnaamijyada Pascal, tiro ka mid ah qaar ka mid ah bytes ee xasuusta waxaa loo qoondeeyey markii barnaamijka bilaabo. Tani waxaa lagu go'aamiyaa nooca variable ah, tusaale ahaan, calaamad u ah mid ka mid byte, nooc ka mid ah abyoonaha - laba bytes, nooca dhab ah - afar bytes. Sidaa darteed, marka aragti ah ee isugu soo ma aha weyn, barnaamijka uma baahna xaddi weyn oo RAM. Haddii kale, barnaamijyada waxay yeelan doonaan in la helo siyaabo kale inay ka qaybgalaan oo isdiyaarin kara, tusaale ahaan, in file ama in a taallo la tilmaamo.
