Definition
Noun: A run-time error is a type of software error or bug that occurs while a program is executing (running). It is an error in the program's logic or arithmetic that was not detectable during compilation or initial testing and only manifests itself during the program's execution under specific conditions.
Usage
This term is used in computer science and software development to describe a specific class of program failures. - It is typically contrasted with compile-time errors, which are detected before a program runs. - A run-time error often causes a program to crash, freeze, or produce incorrect results.
Examples
Advanced Usage
- "to throw a run-time error": When a program actively generates and reports a run-time error.
- The function will throw a run-time error if the file is not found.
- "run-time error handling": The practice of writing code to gracefully manage and recover from run-time errors (often using blocks).
- Good run-time error handling prevents the application from crashing unexpectedly.
