the benefits of exception handling are as follows, (a) Exception handling can control run tune errors that occur in the program. (b) It can avoid abnormal termination of the program and also shows the behavior of program to users. (d) It can separate the error handling code and normal code by using try-catch block.
What are the advantages of exception handling Mcq?
