I found the last question interesting.
16.How can i restrict creation of objects of a class upto five only?

Well I believe it can be done by have SingleTon Class which can be instantiated at max five times.This is the way you will go for it.
1.Create a public class.
2.Make its contructer as private.(No outside object can instatiate it)
3.Write a public Static Method CreateInstance that creates the instance of tyhe class on demand and keep a class member to track the number if instance.
4.If the number of instance exceeds 5 then dont create instance rather use an earlier instance.
It goes like this:


publicclassClass1
{
privatestaticint counter = 0;
privatestaticClass1 instance;
privatestaticObject obj = newObject();
private Class1()
{
}
publicstaticClass1 CreateInstance()
{
lock (obj)
{
if (counter > 5)//couter > 0 means instance is not null
{
return instance;
}
else
{
counter++;
instance = newClass1();
return instance;
}
}
}
}
