A delegate is a reference pointer to a method. When it is called, it gives notification to all methods that reference the delegate. It allows us to treat a method as a variable and pass method as a variable for a callback. The basic idea of a delegate is exactly the same as a subscription magazine. Anyone can subscribe to the services and they will receive the update at the right time automatically.
TYPES of Delegate:
1.Single Delegate:- It can reference to only single method at a time.
2.Multicast Delegate:- It can store the reference of multiple methods at a time.
