Introduction
Public access specifier means, any public
member can be accessed from inside and outside the class. Public access
specifier allows a class to expose its member variables and functions
to other functions and objects.
Example
using
System;
using
System.Collections.Generic;
using
System.Linq;
using
System.Text;
namespace
public_access_specifier
{
class
rectangle
{
public
double length;
/*Public member variable define
Length and width , which can be access in
main() function, using
in instance of the rectangle class , named rect. */
public
double width;
public
double ReturnArea()
/*The member function ReturnArea()
and Display() can also access
variables directly
without using any instance of the class*/
{
return length *
width;
}
public
void Display()
{
Console.WriteLine("Length={0}",
length);
Console.WriteLine("Width={0}",
width);
Console.WriteLine("Area={0}",
ReturnArea());
}
}
class
ExecuteArea
{
static
void Main(string[]
args)
{
rectangle
rect = new
rectangle();
rect.length = 4.5;
rect.width = 3.5;
rect.Display();
/*The member function Display()
is also declare Public, so can also be accessed
from main() using in
instance of the Rectangle class, named rect */
}
}
}
