Run time error

Run time error, also known as a runtime error, is an error that occurs when a program is in execution, or “running”. Unlike a compiler error which occurs when a program is translated from a programming language into its binary form, a run time error occurs when an application is running and due to the combination of code and data, the application is not able to complete its work.

Run time errors can either be fatal, meaning the program is unable to continue its work, or the error may be recoverable, meaning the program can use techniques such as exception handling to recover from the error and continue working. The cause of a runtime error can vary, including incorrect or incorrect input, incorrect calculations, bugs in the program, or data that is unexpected by the application.

One of the most common types of run time errors is a memory access violation, which occurs when a program attempts to write, read, or execute memory that it is not authorized to do so. This can happen due to incorrect data values, incorrect pointers, memory leaks, or buffer overflows.

In order to prevent the occurrence of run time errors, it is necessary to perform code reviews, use debugging tools, and test for errors. It is also important to use built-in exception handling wherever possible in order to handle any unexpected data or circumstances.

In conclusion, run time errors are errors that occur when a program runs, and can range from fatal errors that stop the program from working to recoverable errors that can be dealt with using exception handling. In order to detect and prevent run time errors, it is important to perform code reviews, use debugging tools, and test for errors.
