RuntimeFehler

RuntimeFehler, also known as runtime errors, are problems that occur during the execution of a computer program. Unlike compile-time errors, which are detected by the compiler before the program runs, runtime errors manifest while the program is actively running. These errors can cause a program to crash, behave unexpectedly, or produce incorrect results.

Common causes of runtime errors include issues such as division by zero, attempting to access memory that has not been allocated, invalid data type conversions, or infinite loops. For instance, if a program tries to divide a number by zero, it will encounter a runtime error because this operation is mathematically undefined. Similarly, trying to use a variable that hasn't been assigned a value or attempting to access an array element outside its valid range can lead to such errors.

When a runtime error occurs, the operating system or the runtime environment typically terminates the program and may display an error message to the user. Debugging runtime errors can be challenging as they are not always immediately apparent and can depend on specific input data or system states. Developers often use debugging tools to step through the program's execution, inspect variable values, and identify the exact point where the error originates. Proper error handling mechanisms within the code can help mitigate the impact of runtime errors, allowing the program to recover gracefully or provide more informative feedback instead of crashing.
