Answer / cool
Delegate is a strong type function pointer and it passes the
method signature for the class and class that has this
signature can use this delegates.
This is similar to Pointers in C and C++.
If we use this delegates for single method then this is
single case and if the method declared to more than one
method then this is called as multicast delegate object

Answer / subbu
Delegates are a type that references method. Normally when
we calling a method we will pass some data to that method
as input parameter. But in some scenario we might need to
pass method as input parameter to other method in such case
we can use delegate.
Delegate wraps any method which matches its signature,
calling a delegate result in calling a method so this gives
the ability to call the method programmatically based on
our business needs.
