what is the purpose of an Interface ?

Hi,
Suppose, i have an interface A and i implement that in a class....

interface A
{
void show();
}

Class implementInterface: A
{
void show()
{
Console.WriteLine("dotnetfunda");
}
}



Now, if i have to define a method in a class then what is the purpose of declaring a skeleton somewhere else ?

Any help is appreciated.....
Thanks and Regards
Akiii

As I know, C++ level languages has multiple inheritance features and in .net for the same we uses interfaces. This feature is not for small apps.
