Presentation Transcript

  1. C++ Programming Practice Time Week 6.

  2. This • Pointer for current executing instance

  3. Practice : Static Member Member not on instance, but on definition Share-able in all instance of same class

  4. File Separate Implement Define

  5. Practice : Friend • Please Check Professor’s Material

  6. Practice : Operator Overloading • Overload • operator << (int Int_Val) {printf(“%d”, Int_Val;)} • operator << (const char* pCh) {printf(“%s”, pCh;)} • … • Override • Base Class function f_A • Derived Class function f_A • BaseClass *pBc = new DerivedClass(); • pBc->f_A(); //Derived Class function f_A will be called

  7. Inheritance • ex) • Room • Rm_Quiz, Rm_Dead, Rm_End

  8. Method Overriding

  9. Protected • Allowed • Inner • Derived Class • Denied • Outer • Derived’s Derived

  10. Constructor Chain • Base Class : Room • Derived Class : Rm_Dead • When Rm_Dead created. • 1) Room’s constructor called • 2) Rm_Dead’s constructor called • From Deep, To Shallow

  11. Polymorphism • Override • Base Class function f_A • Derived Class function f_A • BaseClass *pBc = new DerivedClass(); • pBc->f_A(); //Derived Class function f_A will be called • Type : BaseClass • Instance : DerivedClass

  12. Protected • Derived class will implement virtual function for its purpose

  13. The End of Week 6.
