Seventh Class (Parameter)

Seventh class material (function with parameter, Instance Variable)

Function with parameter

public static void Main(string [] args)

This is called function with parameter, Here (string [] args) is called parameter.

'string' is Data type ' [] ' is array and 'args' is name of variable or name of array.

Example : 1


using System;
class arr
{

public void abc(int a, int b)
{
int c=a+b;
Console.WriteLine("Sum is : "+c);
}
public static void Main()
{
arr d=new arr();
d.abc(3, 5);
}
}

Instance Variable and instance function/method/behaviour



using System;
class Instance
{
int a, b, c;
public static void Main()
{
Instance i=new Instance();
i.a=2;   //we can declare here also like this    i.a=2;i.b=3;
i.b=3;
i.c=i.a+i.b;
Console.WriteLine("Result is : "+i.c);
}
}

Instance Function

using System;
class Instance
{

public void Roy()
{
      Console.WriteLine("this is Believe Techno");
}
public static void Main()
{
Instance i=new Instance();
i.Roy(); //it called instance function

}
}

Access Variable and Function without instance.

using System;

class roy

{

public static int a,b,c;

public static void believe()

{

Console.WriteLine("Hi static function");

}

public static void Main()

{

                believe();   //we dint need here to make object or instance..

a=3;b=4;

c=a+b;

Console.WriteLine("Result is :"+c);

}

}

Non static variable cannot access in non static function without instance but static variable can directly access to the static function.
