Why do we need interfaces?..

Answer / shivacharan

Reason1: In C# Multiple inheritence concept will be
implemented by Interfaces.
Reason2: When multiple ppl are working on one sigle
project, if they need to use some common functionality (for
example initializing the variables for thier modules)
instead of writing their own function name (like init,
initialize, setup etc etc) if we can write one single
function name (lets say initialize) then this function can
be implemented by any user who derives. That's it.

public interface IInitialize
{
void InitializeVar();
}
public classs Box:IInitialize
{
void InitializeVar()
{
//initializion of variables goes here
}
public classs Rectangle:IInitialize
{
void InitializeVar()
{
//initializion of variables goes here
}

this wil avoid all the confusion
