overloading:-
-------------- function name same and parameters in the functions are different
class function
{
public string find_big(int a, int b)
{
//source code
}
public string find_big(float a, float b)
{
//source code
}
function overridding:-
------------------------in this function name same and the difference is inherits the 2nd class(derived class) from 1st class(base class)and
use the virtual to base class and override to derived class
virtual:-
----------
if we use virtual then the function calls once. it's c++ style
eg:-
class one
{
public virtual void display()
{
System.Console.WriteLine("one:display");
}
}
class two : one
{
public override void display()
{
System.Console.WriteLine("two:display");
}
}
