UHlelo Modular

iinkqubo seemodyuli isebenza kumgaqo "Yahlula kwaye lulawulo". Worth uphenyo.

iinkqubo seemodyuli kubandakanya ukuhlengahlengisa inkqubo njenge ezininzi ibhloko ezizimeleyo amancinci-ertyisi, leyo adla ngokuba iimodyuli, indlela yokuziphatha kunye nesakhiwo zizinto kakhulu ngokupheleleyo owayamileyo imigaqo ethile. Kubalulekile ukwabelana ukusetyenziswa ingcamango "unit" xa kukho imbono le syntactic unit kolwimi yenkqubo naxa iyunithi sisenokukhathazwa kwenkqubo enkulu phakathi zaziibloko eziliqela ezinokuthi kwenziwa ngohlobo iinkqubo, kwakunye kwi ngohlobo kwemisebenzi. Ukusetyenziswa iinkqubo seemodyuli kwenza kube lula ukuba lula inkqubo yovavanyo kunye ubhaqo kwangethuba iimpazamo. It enokwahlulwa ngokungqongqo imisebenzi iintsimbi-oxhomekeke kwezinye yayo, nto leyo eya kuphucula ukuhamba kweenkqubo lusekiwe. Iimodyuli ixesha ukugxeka ukutshintsha ngokwahlukileyo, leyo lula kakhulu inkqubo kwaye yenza ukusebenza iphezulu kakhulu. Ukongeza, iinkqubo seemodyuli kulula kakhulu ukuqonda, kuba modyuli zingasetyenziswa ngempumelelo iibhloko zokwakha ezinye iinkqubo.

Igama elithi "imodyuli" ngokwawo waqalisa kusetyenziswa iinkqubo ngokunxulumene ngokuqaliswa komgaqo seemodyuli xa ubhala iinkqubo. Ngeminyaka, imodyuli ebizwa ezinye uhlobo umsebenzi okanye inkqubo, leyo ibhalwe ngohlobo imithetho ethile. Ukususela ngelo xesha ayakhekanga iimfuno eyamkelekileyo, kumnqongo kuthiwa nayiphi na inkqubo ogama lingu- ukuya imigca mahlanu. Parnassus kuqala concretized kwasekwa iimfuno lomnqongo: ". Ukuze ukwenza kumnqongo ngalunye kufuneka kwanele ukuba ulwazi encinci malunga imixholo ezinye" Kubonakala ukuba ixesha lokuqala Parnassus wabumba ingqiqo ngolwazi ezimela kweenkqubo. definition kwakhe kusenza ukuba yokuba imodyuli ongathi uthunyelwe kuyo nayiphi na inkqubo single njengoko kwanala nqanaba liphezulu weqela legunya. Ukholosile ukufihla ulwazi abukhange bufikelelwe ngenxa ukusetyenziswa kwezakhiwo ezikhoyo ngelo xesha, ekubeni phantsi eziphawulekayo eziguquguqukayo zehlabathi kunye nokuziphatha kwabo Kunzima ukuqikelela kwiinkqubo ezintsonkothileyo. Kwafuneka ukwenza isakhiwo ukuba uyazimela kula variables. Yaba kuye igama mnqongo wokulinganisela, kwaye zisekelwe phezu kwawo, waza wazalwa iinkqubo yemodyuli.

Ekuqaleni bekucingelwa ukuba ukuphunyezwa kweenkqubo software enzima lingaphunyezwa usebenzisa lo mnqongo belingana kunye nemisebenzi kunye neenkqubo njengoko nokwakhiwa bamanyane ifihle iinkcukacha ukuphunyezwa subtask ethile. Kodwa Turbo UPascal ngolwimi nto ayizange ilandelwe ngokupheleleyo umgaqo iinkqubo yemodyuli. Olu lwimi akayixhasi iimodyuli yangaphakathi epheleleyo, ngenisa ukusebenza ngokwaneleyo bhetyebhetye, kuba akavumeli ukungenisa izinto naziphi na ezinye iimodyuli. Impembelelo emanyeneyo oku nesibakala sokuba kunye kunyebeleziso computer landiswa kakhulu uluhlu lwabantu lwenkqubo, leyo kunciphise ngokungqinelana nenqanaba yokuxhoba yeengcingane, kwakhokelela ekubeni uphuhliso iimodyuli yesicelo zasetyenziswa njengendlela yokudala ingxaki kwamathala kwemisebenzi kunye neenkqubo. badwelisi benkqubo abaqeqeshiweyo kuphela wasebenzisa amandla ngokupheleleyo izakhiwo zolwimi zonke izinto esakhiweni imisebenzi.

Ukuba ujonga iiyunithi UPascal ngokwembono wenkqubo, inombolo yazo kufuneka imiselwe yokubola ingxaki kwinani sub-misebenzi, elizimeleyo nganye enye. Kwimeko egqithiseleyo, umnqongo zingasetyenziswa kwisigqibo oko unyango omnye kuphela, ukuba kuyimfuneko, ukuze Namanyathelo athathwa kwingingqi ukuba ikhutshwa phandle, ukuba uzimele ngokupheleleyo kwimpembelelo kwezinye iinxalenye nkqubo kunye neenguqu ezenziwe kwisiyilo khowudi.
