What type of errors does a programming runtime error typically indicate?

A programming runtime error typically indicates bugs that were not handled during the design phase. During execution, the program encounters scenarios that the programmer did not anticipate or account for, leading to unforeseen consequences that disrupt the normal flow of the program. These errors often arise from improper handling of user inputs, resource allocation issues, or unexpected states that can be reached during execution.

When designing a program, it is crucial to handle potential exceptions and edge cases that may not occur during initial testing. A runtime error serves as a reminder that there are underlying assumptions in the code that were not robustly validated, meaning that the program cannot continue to execute as intended under certain conditions. Therefore, understanding and addressing these bugs during the development phase is essential to creating stable and reliable software.
