Indlela ukudala itafile inyaniso ngenxa yokubonakalisa ezinzima zilandelelana

Namhlanje siya kuzama ukucacisa nokudala indlela itafile inyaniso kokuvakaliswa ngendlela esengqiqweni. Qaphela ukuba algebra Boolean ifunyenwe, ubuncinane imisebenzi emithathu yoviwo karhulumente emanyeneyo. Ukuba ufunda eli nqaku, ngoko ngokuqinisekileyo ufumane amanqaku ngakumbi ukuhlolwa kwinzululwazi yekhompyutha.

imisebenzi

Phambi kokuba wenze netafile inyaniso, sinikela aqhelane nokusebenza algebra Boolean.

Siya kuqala abazana wethu umsebenzi kuphika. Libizwa ngokuba inversion. Nanku umzekelo: ". Namhlanje Ndiza-bhanya" ibinzana Faka kuyo isichasi, ngenxa esinayo: "Namhlanje andiyi Ndisaya-bhanya."

Ngoku makhe sithethe malunga nemisebenzi phinda Ukongeza, aljebra Boolean, kuba amagama - kubanjiswene kunye disjunction ngokulandelelana. Masithi sithi, "hamba uye movie, ukuba ufunde isifundo kunye inkunkuma vynesesh". Kwesi sivakalisi igama elithi "yaye" yenza umsebenzi ngesihlanganisi, yaye "ukuba" - disjunction.

Umphumela onengqondo - oku omnye umsebenzi logic unzima iqulethe amabinzana ezimbini: i imeko kunye yoko. Ukuba ukuchaza ulwimi Russian, isindululo yakhelwe ijikeleze ndlela ilandelayo: "Ukuba ixesha ukufunda iincwadi, ngoko hamba uye iimovie." Inxalenye isindululo phambi kokuba kwesishumi - imeko kwaye emva kokuba kwesishumi - njengesiphumo.

Ngoku, ngokufutshane malunga umsebenzi ukulingana okanye esilingana. Ukuze acha- ulwimi Russian kule meko kunzima. Kuba ukulingana kufuneka sikhumbule ukuba la mabinzana mabini anezinto mhlawumbi bobuxoki okanye yinyaniso, ngoko isiphumo HIV, oko ilingana omnye.

algorithm

Ngoku siza kuthetha ukwenza indlela itafile inyaniso kwinzululwazi yekhompyutha, okanye mandithi, siza kuxubusha algorithm yezenzo zethu.

Betafile ukuzoba, kuyimfuneko kuqala ukufumanisa inani iiseli, lwemiqolo nemihlathi. Siza kwenza konke inyathelo emva kwelinye.

• Siza kuqinisekisa inani lemiqolo. Ukuze wenze oku, ukubala inani variables ifakiwe elithi, limise ezimbini kule nombolo. Umzekelo, ukudala itafile inyaniso, yaye ngakumbi kanye ukuchonga inani imigca kokuvakaliswa yezahlukileyo ezintathu? Ezimbini aqonde kumlinganiselo wesithathu uze ufumane ezisibhozo. iminqwazi ngaphandle, kufuneka thina imikrozo ezisibhozo.
• Ukuze kubonwe inani lwemihlathi, kufuneka ukuba ukubala kunye nemisebenzi inani elithi. Umzekelo, ngokubhekiselele HEA * C + B kuzo zonke zontathu imisebenzi. Lokuqala - i kuphika, ukuvumelana - phindo leyesithathu - ngaphandle. Ngoko ukuze bazalise amaxabiso lwemisebenzi kufuneka thina imiqolo emithathu. Kodwa kufuneka athathe ingqalelo into yokuba ibinzana elithi yethu iqulathe kweziganga ezithathu, kwaye kufuneka ukuba ugcwalise nendibaniselwano zazo kunokwenzeka, ukudibanisa izithethi ezintathu. Iyonke uphendulela 6.
• Okulandelayo, yiya sengigqi lwendibaniso kweziganga kunye kwetafile ukugcwaliswa kunokwenzeka. Qiniseka ukuba siqwalasele ophambili imisebenzi.

Umzekelo lokuqala (variables ezintathu)

Sinikezela wena ukusombulula le ngxaki zilandelayo: ukubala ukuba zingaphi iindibaniso ukwanelisa imeko F = 1 ibinzana (HEA + B) + A * HEC. Ngoku, ukuba ukwenza njani itafile inyaniso ukusombulula le ngxaki. Enlists uncedo ekwenzeni algorithm isenzo.

1. Inani lemiqolo = 9 (ezisibhozo imidibaniso kweziganga + omnye umgca - ikepusi itafile).
2. umsebenzi kuqala: 1- inversion 2 - Ukudibanisa elikwizibiyeli-3 - ukuba inversion of C 4 - phindo, 5 - Ngaphezu.
3. Inani Columns = 8.
4. Ukudrafta iitafile kunye nokugcwaliswa.

1. Ukufumana impendulo yombuzo.
2. impendulo Rekhoda. Impendulo: 6. Qaphela ukuba imeko yomsebenzi ucelwa ukuba zingaphi iindibaniso wonelisekile, kodwa musa bacele ukuba ukuzibala.

Umzekelo wesibini (variable 4)

Sinikezela ukuba ucinge: indlela yokwenza itafile inyaniso ngenxa ifomula: A * B * HEC + D? Yintoni liyangqinelana nenani lwendibaniso: F = 0.

Siza kuphumeza ngamnye algorithm efanayo. Inani lemigca kule meko yandiswa kwi-17, ze kwikholam - ukuya 8. imisebenzi ephambili:

1. A * B;
2. HEC;
3. phinda iziphumo umsebenzi wokuqala nowesibini;
4. Ukudibanisa japan operation wesithathu ixabiso variable D.

Sicebisa uzama ukwenza wena bagcwalise itheyibhile uze athethane iziphumo kweli candelo nqaku.

Ukususela itheyibhile ngenxa sigqiba: le meko uyaneliswa imidibaniso 7 ezahlukeneyo nesebenzayo.
