Question

Which of the following is the most preferred way of throwing and handling exceptions​

Answer 1

Answer:

Throw by reference and catch by reference.

Answer 2

The most preferred way of throwing and handling exceptions​ is to throw by reference and catch by reference.

• Throwing and handling exceptions by reference is better than by value as it is much more optimal and efficient.
• If we want to change the value of the variable later then this will cause problems if we throw and handle exceptions by value instead of reference.
• Another problem that arises is object slicing.
• Thus,  throw by reference and catch by reference  improves performance and the preferred way of  throwing and handling exceptions​
