Chapter 12: Problem 3

If an exception is thrown and the program does not handle it, what happens?

Short Answer

Expert verified

Answer: The consequences of unhandled exceptions include loss of unsaved data or progress, unexpected application termination, and potentially incorrect application behavior.

Step by step solution

Understanding Exceptions

Exceptions are events that occur during the execution of a program indicating an error or an exceptional condition. When an exception is encountered, the normal flow of the program is disrupted, and the program jumps to a specific code block called an exception handler.

Handling Exceptions

To handle exceptions, most programming languages support the use of a try-catch block. A try-catch block is a code structure that allows the program to execute some code (within the try block) and catch any exceptions that might occur (within the catch block). If an exception occurs, the program control is transferred to the catch block where the exception can be processed or logged.

Unhandled Exceptions

If an exception is thrown and the program does not handle it (i.e. there is no catch block or an appropriate exception handler), the unhandled exception causes the program to terminate abruptly. This is because the program cannot continue its normal execution, as it does not know how to resolve or react to the error that has occurred.

Consequences of Unhandled Exceptions

The consequences of unhandled exceptions include the loss of any unsaved data or progress, unexpected application termination, and potentially incorrect application behavior. It is essential to handle exceptions properly in any program to ensure smooth execution and prevent unexpected termination.
