runtime error

A programmer sees a runtime error message on their computer screen.

Definition
  1. Noun:
    • A software error that occurs during program execution: A "runtime error" is a type of computer program error that happens while the program is running (executing), as opposed to errors detected during compilation. It indicates a flaw in the program's logic or arithmetic that prevents normal continuation.
Usage
  • The term "runtime error" is used to describe a specific class of software failures. It is typically encountered by users or developers when a program crashes or displays an error message during operation.
  • It is a countable noun (e.g., , ).
Examples
  • Noun:
    • The application crashed due to a runtime error in the calculation module.
    • Debugging tools help programmers identify the source of a runtime error.
    • A common runtime error is division by zero, which the program's logic failed to prevent.
Advanced Usage
  • "to throw/cause a runtime error": Used to describe the action of a program generating this error.
    • The faulty input data caused the program to throw a runtime error.
  • "runtime error handling": Refers to the techniques in programming designed to manage and respond to these errors gracefully.
    • Good runtime error handling can prevent a program from crashing unexpectedly.
Variants and Related Words
  • Runtime (n): The period during which a program is executing. (e.g., )
  • Logic error (n): A broader category of programming mistake that leads to incorrect output or behavior, often causing a runtime error.
  • Exception (n): In many programming languages, a runtime error is represented and handled as an "exception."
Synonyms
  • Execution error: An error that occurs during the execution phase of a program.
  • Program crash/failure: A general term for when a program stops working, often due to a runtime error.
Related Phrases
  • "Catch a runtime error": In programming, to use a structure to detect and manage an error when it occurs during execution.
    • The try-catch block is used to catch a runtime error and display a friendly message.
  • "Unhandled runtime error": An error that occurs but is not managed by the program's code, typically causing it to terminate.
    • An unhandled runtime error caused the software to close abruptly.
Related Idioms

(Note: As a technical term, "runtime error" is not commonly used in figurative idioms. Its usage is almost exclusively in computing contexts.)
