what is C# ?

There has been BCPL, C, and C++; Microsoft recently introduced yet another language in the same naming tradition: C# (pronounced "C sharp"). C# is a language designed to be fully compatible with Microsoft's .NET initiative while taking advantage of what has been learned from C and C++ (as well as Java).

C# is designed to be a platform-independent language in the tradition of Java. It's syntax is similar to C and C++ syntax, and C# is designed to be an object-oriented language. There are, for the most part, minor variations in syntax between C++ and C#. Main has no return type, there are no semicolons after class names, there are some (to C++ programmers) strange decisions regarding capitalization - such as the capitalisation of Main. Other a few differences, the syntax is often the same. This decision is reasonable, in light of the fact that C syntax has been used with several other languages - notably Java.

Similar to Java, C# does not support multiple inheritance; instead it provides Java's solution: interfaces. Interfaces implemented by a class specify certain functions that the class is guaranteed to implement. Interfaces avoid the messy dangers of multiple inheritance while maintaining the ability to let several classes implement the same set of methods.


Another helpful feature of C# is garbage collection. Therefore, it is unnecessary to include a destructor for each class unless a class handles unmanaged resources; if so, it's necessary to release control those resources from within the class (The Finalize function is used to clear up these unmanaged resources; it can even be abbreviated with the same syntax as a C++ destructor). Of course, C# also provides direct access to memory through C++ style pointers, but these pointers are not garbage collected until specificially released by the programmer.

Polimorfisme

Polimorfisme membolehkan objek yang berbeza meggunakan fungsi anggota(mesej) yang sama tetepi....membawa kesan yang berbeza. Kesan bergantung kepada jenis objek yang dirujuk.

contohnya....rupa bentuk geometri fungsi anggota KIRA_Luas untuk mengira keluasan objek geometri boleh juga digunakan untuk mengira keluasan mana-mana jenis objek geometri dan hasilnya bergantung kepada bentuk yang dirujuk.

Polimorfisme boleh dilaksanakan melalui perwarisan. Ia boleh membentuk sati hierarki kelas terbitan dan fungsi anggota yang berkenaan ditakrif semula untuk menyesuaikan dengan kelas terbitan. Dengan itu fungsi anggota yang sama boleh digunakan ke atas beberapa kelas yang berkaitan.

contoh :

Arahan: Keluarkan duit dari mesin ATM

objek1: mengeluarkan dari mesin ATM di Bank Islam
objek2: mengeluarkan dari mesin ATM di CIMB

Perwarisan dalam C++

Perwarisan adalah cara mengunakansemula kod yg telah dibina bagi suatu kelas yang sedia ada. Konsep ini sama seperti anak-anak mewarisi sifat ibubapa. Oleh demikian, anda boleh membina kelas yang mewarisi data ahli & fungsi ahli dari kelas yang sama. Kelas Asas adalah kelas yang sedia ada, manakala kelas Terbitan adalah kelas yg diterbitkan dari kelas Asas. Kelas terbitan mewarisi kelas asas.kaedah ini bertujuan untuk menjimatkan masa dan tenaga. Cuma anda perlu tambah(sekiranya perlu) di data fungsi atau fungsi ahli dalam kelas terbitan.


Terdapat dua kondep perwarisan dalan C++:

1. Perwarisan Tunggal:

kelas asas <----kelas terbitan C<---- kelas terbitan B

2. Perwarisan Pelbilang

kelas terbitan A <-----Kelas B -----> kelas terbitan C


Sintak bagi perwarisan ialah:

class NamaKelasterbitan: penentu capaian Kelasterbitan
{

data ahli;
fungsi ahli;
}

*penentu capaian = private, public, & protected


contoh aturcara:

class Bentuk
{
private:
int unit;
public:
int ID;
Bentuk( )
{ cout<<"Saya adalah bentuk"<< endl;
}
};

class Bulat: public Bentuk
{
public:
Bulat( )
{
cout<<"Saya bentuk bulat"<< endl;
}
}

kelas bulat mewarisi secara public dari kelas bentuk. Oleh itu data dan fungsi ahli diwarisi oleh kelas bulat. Walaubagaimana pun data ahli (private) bagi kelas Bentuk tidak dapat diwarisi oleh kelas bulat.

Schema Question 2: Practicaal Test 1

#include

class Barang
{
public:

int barang[4],purata;


public:

void bacanilai()

{ int jum=0;


for( int i=0; i<=4; i++)

{
cout<<"Masukkan barang["<< i <<"] nilai barang RM:"<< endl;
cin>>barang[i];
jum+=barang[i];

}

cout<<"jumlah terkini RM:"<< jum << endl;
purata = jum / 5;

}

void paparnilai()

{ cout<<"jumlah harga 5 barang seluruh RM:"<< jum << endl;
cout<<"jumlah purata 5 barang seluruh RM:"<< purata << endl;

}

};

void main()
{ Barang barangA;
barangA.bacanilai();
barangA.paparnilai();
}

Public, Private & Protected

C++ membolehkan pengaturcara menentukan capaian kepada ahli data dan fungsi ahli g ditakrifkan dgn menggunakan penentu capaian yang berlabel "public", "private", atau "protected".

"...ahli data atau fungsi ahli yg berlabel publis boleh dicapai dari luar kelas melalui nama sesuatu objek.."

"...manakala jika berlabel private atau protected cuba boleh dicapai oleh fungsi ahli atau fungsi rakan (friend)..."

...ini bermakna capaian private menghalang capaian dibuat dgn sewenang-wenangnya oleh fungsi yg bukan fungsi ahli kelas tersebut.

...data2 sulit biasanya dilabel sebgai provate di dalam kelas ia utk mengelakkan data diubah suai atau di rosakkan dari luar
