  1. Programim C++ Klasat, Objektet, Instancat, Metodat (Shembuj)

  2. Hyrje • C++ u ndertuasinjeurelidhese midis OOP dhe C, gjuha me popullore e programimitteprogramevekomerciale ne treg. • Llojiitedhenave (data type) natregon per: • Madhesine ne memorieqenxe • Cfarellojinformacionimundtembaje • Cfareveprimeshmundtekryhenmbite • Ne ndertojmellojeterejatedhenash, sepsenaduhetteballafaqohemi me situatakuvetemnumratdhekarakteretnukmjaftojne (data types tipike)

  3. Llojeterejavariablave • Llojet e rejatetedhenave, krijohen duke deklaruarnjeklase (class) • Njeklase, eshtenjebashkesivariablash – zakonishtllojetendryshme – tebashkuara me njebashkesifunksioneshqekanelidhje me njeratjetren. Psh: njemakineeshtenjebashkesirrota, dyer, pasqyra, xhama, etj. Dheajoecen, ndalon, shpejton, kthehet, etj.

  4. Member Variables dhe Member Functions • Njeklase (class) mundesonqetebashkoshveprimetdhepjesetperberesene njekoleksion, dheketekoleksion ne e quajme OBJEKT(object). Kjo ka shumeavantazhe. • Variablat (ndryshoret) ne njeklasenjihensi: member variables ose data variables. Ketojanevariablat e klases (class variables) dhejanepjesetperberesetemakines: rrotat, timoni, pasqyrat, etj. • Funksionet ne njeklase, zakonishtmanipulojnevariablat (member variables). Ketonjihensi member function, osemetoda (methods of a class). Metodat e makines do teishin: nisu(), mbajFrena(), kthehu(), etj.

  5. DeklarimiiKlasave • Per tedeklaruarnjeklase, perdoretfjalakyce: class e ndjekurngakllapa{ , me pas listohen data members dhefunksionetqe do tepermbaje, dhe ne fund mbyllet me } • class Cat { unsigned intitsAge;unsigned intitsWeight; void Meow(); } • Kurdeklarojmenjeklasenukrezervojmendonjehapesire ne memorie. NjeklaseMace do tekishte data members per moshen, ngjyrendhepeshensiedhe methods per flen(), vrapon(), mjaullin() MosHarro: C++ eshte case-sensitive

  6. DeklarimiiObjekteve • Njeobjektillojitteriqejukenikrijuar, deklarohet ne tenjejtenmenyresikursedeklarohetnjevariabelitipit standard. Psh: • unsigned intMosha; //deklarojnjeinteger • MaceFrisky; //deklarojnjemace • Nëkëtërast Frisky eshtenjeobjekt e llojit Mace – ngjashem me Mosha, qeeshtenje variable e llojit unsigned integer • Objektieshtenjeinstancë e njeklase.

  7. Aksesimii ‘Anetareve’ tenjeKlase (class members) • Per teaksesuar members tenjeklase, perdoretpika (.) ose ne eng. ‘dot operator’. • Per tecaktuarpeshen e maces Frisky, shkruajme ne keteforme: Frisky.itsWeight = 50; • Per tetherriturnjefunksionteobjektit: Frisky.Sleep(); • Ne keterast, therritetmetodaSleep() e Friskyt. Data member objekti Method / function objekti

  8. Dhënia e Vlerave • Ne C++ vleranukijepetllojit, porvariablit! • Shembull: • int = 3 gabuar • int x = 5 sakte • Mace.itsAge=5 gabuar • Cat Frisky Frinsky.itsAge=5 sakte JepivleraObjektitjoKlases!

  9. Public VS Private • Edhepse ne ndertojmenjeklase, nukmundteperdorimtedhenat / anetaretqejane private. Per ketearsye, deklarojme: class Cat{ public: unsigned intitsAge; unsigned intitsWeight; void Meow(); } • Kjobenqe, itsAge, itsWeightdhe Meow() tejenepublike – dmthteaksesohenjashteklases.

  10. Sintaksa class classname { Access - Specifier: Member Varibale Declaration; Member Function Declaration; }

  11. Permbledhje PERDOR • Perdorfjalen class per tedeklaruarnjeklase • Perdorpiken (.) per teaksesuaranetaret e njeklase • MOS • Mosngaterrodeklarimin me caktimin. • Mosngaterroklasen me objektin. • Mosijepvleranjeklase, poranetarevetenjeobjekti
