Explanation of Solution

Exception:

In C++, the exception is an object used to signal the unexpected error occurred during a program execution.

• An exception has been thrown when an error has been occurred in a program.

Exception Handler:

The “throw point” is a statement which uses the keyword “throw” to throw an exception which occurred while executing the program.

• After the execution of “throw” statement, the program control will move to another part in the same program to handle the exception is called as “exception handler”.
• In order to handle an exception, construct a “try/catch” block in a program.

The “try” block:

• The “try” block is starts with the keyword “try” and it contains the code which will have the possibility to generate an exception.
• The “try” block must be followed by one or more “catch” blocks which are denoted as exception handlers.

The “catch” block:

• The “catch” block is starts with the keyword “catch” and it is followed by an “exception parameter”...
