Question

Briefly describe what an exception is.

Short answer

Short Answer: An exception is an event that arises when a program encounters an error, invalid data input, or unexpected condition, disrupting its normal flow of instructions. These events can occur due to various reasons, such as invalid user data input, accessing unavailable resources, runtime errors, or out-of-bounds access to data structures. Programmers can handle exceptions using try-catch blocks to maintain the normal flow of the program while addressing the issues.

Step-by-step solution

Definition of an Exception

An exception is an event that occurs during the execution of a program when the program encounters an error, invalid input or an unexpected condition. Exceptions disrupt the normal flow of the program's instructions.

Why Exceptions Occur

Exceptions may occur for various reasons, such as: 1. Invalid data input by the user 2. Unable to access resources like a file or a database 3. Runtime errors in the program, such as arithmetic operations like division by zero 4. Out-of-bounds access to arrays or other data structures

Handling Exceptions

In most programming languages, exceptions can be handled using try-catch blocks. The code that may encounter an exception is placed in the try block and the corresponding catch block is used to handle the exception if it occurs. This allows the programmer to maintain the normal flow of the program while also dealing with any errors or exceptions that may arise.
