Runtime Error
A runtime error is a type of software error that occurs during the execution of a program, after it has been successfully compiled or interpreted. It typically happens when the program encounters an unexpected condition, such as invalid input, memory issues, or logical flaws, causing it to crash or behave incorrectly. Runtime errors are distinct from compile-time errors, which are detected before the program runs.
Developers should learn about runtime errors to effectively debug and maintain software, as these errors directly impact user experience and application stability. Understanding runtime errors is crucial for implementing robust error handling, logging, and testing strategies to prevent crashes and ensure reliable performance in production environments. This knowledge is essential across all programming domains, from web development to embedded systems.
