Assertion Failed error is a run-time error that indicates that an assertion in the program failed, that is, it is triggered when the condition of the statement that checks the program status is false. It is common in software development and causes include input validation failures, invalid pointers, memory errors, and unexpected code paths, requiring resolution by debugging, inspecting the code, and fixing errors.
Assertion Failed Error
Question: What is Assertion Failed error?
Answer: The Assertion Failed error is a common runtime error in software development, which indicates that an assertion in the program failed. An assertion is a logical statement that checks the state of a program and triggers an error when a condition is false.
Detailed explanation:
- Assertion: Assertion is a statement embedded in the code that checks the internal state of the program. They are often used to ensure that a program behaves as expected.
- Failure: When the condition of the assertion is false, it will trigger the Assertion Failed error. This indicates that the program encountered an unexpected state and there may be a logic error or data error.
- Debugging: Resolving Assertion Failed errors involves examining the assertion that caused the error and determining what caused the assertion condition to be false. This may require debugging code, examining data input and processing, and analyzing program flow.
Common causes:
- Input validation failed (e.g., negative number or invalid format)
- Invalid pointer or null
- Memory error (e.g., access out of range)
- Unexpected code path
Workaround:
- Check the conditions that triggered the false assertion.
- Debug the code to understand what causes the condition to be false.
- Fix bugs in code to ensure assertion conditions are always true.
- If the error is caused by external factors (for example, invalid input), consider adding input validation or error handling to mitigate the problem.
