feilhåndteringen

Feilhåndtering, also known as error handling, is a programming technique used to manage and respond to errors or exceptional conditions that may occur during the execution of a program. The primary goal of error handling is to ensure that a program can continue to operate smoothly or fail gracefully when an error occurs, rather than crashing or producing incorrect results.

In many programming languages, error handling is implemented using constructs such as try-catch blocks, exception handling, or error codes. When an error occurs, the program can "throw" an exception, which can then be "caught" and handled by the appropriate code block. This allows the program to respond to the error in a controlled manner, such as logging the error, displaying an error message to the user, or attempting to recover from the error.

Effective error handling is crucial for creating robust and reliable software. It helps to identify and fix bugs, improve the user experience by providing meaningful error messages, and prevent security vulnerabilities. By incorporating error handling into the design and implementation of a program, developers can create more resilient and maintainable code.
