A Delegate that points to more than one method is called a Multicast Delegate. Multicasting is achieved by using + and += operator.
Consider the Example from question 32.
There are two subscribers for deathEvent, GetPatInfo, and GetDeathDetails. And hence we have used += operator. It means whenever the myDel is called, both the subscribers get called. The delegates will be called in the order in which they are added.
