Week 11

Question 1

Jenis polymorphism?

Answer 1

1. subtype polymorphism, runtime polymorphism
2. parametric polymorphism, compile-time polymorphism
3. ad-hoc polymorphism, overloading

Question 2

perbedaan static dan dynamic binding?

Answer 2

static binding:

1. early binding
2. pengecekan tipe data variable terjadi saat compile time

dynamic binding:

1. late binding
2. run time evaluation

Question 3

pure polymorphism pake jenis binding apa?

Answer 3

dynamic binding

Question 4

parametric polymorphism pake jenis binding apa?

Answer 4

bisa static atau dynamic

Question 5

overloading dan overriding pake jenis binding apa?

Answer 5

static binding

Question 6

syntax pure virtual function? yang tidak memiliki implementasi. class dengan pure virtual function adalah abstract base class

Answer 6

virtual void function() = 0;

Question 7

standar c++ pake static binding. supaya dynamic pake apa?

Answer 7

virtual keyword

Question 8

overriding terjadi saat? perlu inheritance

Answer 8

sebuah function dalam base class punya nama, return type, dan parameter yang sama dan ditulis ulang dalam derived class

Question 9

karakteristik subtype polymorphism?

Answer 9

1. butuh inheritance
2. static binding / early binding
3. compile time
4. overriding function
5. different scope, different class

Question 10

karakteristik parametric polymorphism?

Answer 10

1. execute same code for any type

2. compile time

Question 11

ad-hoc polymorphism?

Answer 11

1. function with same name, act differently
2. overloading function
3. no inheritance
4. static binding
5. compile time

Question 12

syarat urutan overloading?

Answer 12

1. jumlah
2. tipe
3. urutan

Question 13

2 jenis virtual function?

Answer 13

1. pure virtual function

2. quasi virtual function

Question 14

ad hoc polymorphism also called as?

Answer 14

overloading

Question 15

overriding happen only in?

Answer 15

inheritance

Question 16

when overriding happen?

Answer 16

when a function in the base class, with the same name, same return type, and same parameters is re-written or being overwrite in the derived class.

Question 17

c++ by default use what type of binding?

Answer 17

static binding

Question 18

pure virtual method?

Answer 18

only declaring the function prototype / has no implementation. task of function is not defined yet.

contoh:
virtual void function() = 0;

Question 19

abstract base class?

Answer 19

a class with a pure virtual function

Question 20

quasi virtual function?

Answer 20

contain a minimal function, usually blank statement, that should be done by the body function. 
contoh:
class myClass{
    virtual void function() {;}
};

Question 21

if class contain at least one pure virtual method called?

Answer 21

abstract class

Question 22

what is interfaces?

Answer 22

classes that contain abstract methods

Question 23

pure polymorphism?

Answer 23

selection of the appropriate function in a class hierarchy based on the “true” type of the object.

Question 24

Perbedaan static dan dynamic binding?

Answer 24

static:

1. early binding
2. compiler resolve the type of a variable at compile time
3. based on type, including pointer type

dynamic:

1. late binding
2. run time evaluation of the “true” type of an object
3. default in Java

overloading and overriding is (generally) static binding.
parametric polymorphism is either static or dynamic
pure polymorphism is dynamic binding

Question 25

apa itu subtype, parametric, dan adhoc polymorphism beserta code nya?

Answer 25

ayo!

Question 26

Jenis polymorphism yang mengeksekusi code yang sama utk tipe yang berbeda yaitu?

Answer 26

parametric polymorphism
