Array

int[] a = new int[10];

int[0] = 1;

…

Valuable & Array : still same data type


Class: property

class(student)

{

int StudentId;

string StudentName;

double StudentMarks;

}

student s;

s = new student(); ←Constructor or Method

*default 0, NULL or false

Method: action

class Auto

{

string name;

double price;

string color;

int tyreNo;

}

void ChangeColor()

*every method must have return data type.

{

}

Ex.

Message()

{

Console.WriteLine("Hello. How are you?");

Console.WriteLine("What are you doing?");

Console.WriteLine("I'm waiting for you.");

}

Console.WriteLine("Before Method call.");

Message();

Console.WriteLine("After Method call.");

i, j=parameter
1,2=arithmetic


Ex.
Sum(int i, int j)

{

int sum = i+j;

return sum;

}

int d = 10;

int e = Sum(5,6);

int c = d+e;

Console.WriteLine(c);

Result 21


Ex.
void xyz()

{

return xyz; ←error (void means no return.)

}
