Null Coalescing Operator (??)1) A syntax used to check null and assign a default value if null2) This operator can be used with Nullable types as well as reference types.3) This operator can be represented as x ?? y. Here, x and y are left and right operand. Left operand(x) can be nullable type while right operand should have non-nullable value. If the value of x is null then the syntax return the value of y else value of x will be returned. Means value of left operand will be returned if its value is not null else the value of right operand will be returned.Why should we use Null Coalescing Operator (??)?There are numerous of uses/advantages of Null Coalescing Operator:1) It helps in preventing InvalidOperationException. 2) It helps in defining a default value for a nullable item as we did in above program.(assigning a default value 33)3) It removes many redundant "if-else" conditions and makes the code more organized and readable.
