Error codes are a systematic representation of error conditions in a digital system. These codes serve as a codebook for how a system should handle unexpected or invalid input, allowing it to respond appropriately.
How they work:
An error code is typically a numerical value associated with an input or operation.
The code represents a specific type of error, such as "Syntax error" or "Invalid input."
Each error code is associated with a specific interpretation, making it clear how the system should handle the error.
When an input or operation encounters an error, the system interprets the error code and takes appropriate action, such as displaying an error message, halting the process, or logging the error.
Examples:
In a calculator, an error code of "Syntax error" could indicate an invalid expression.
In a database system, an error code of "Data not found" could indicate that the requested data is missing.
When a program attempts to access an invalid file, an error code could indicate an open file or a path not found.
Benefits of using error codes:
They ensure that the system handles errors gracefully and predictably.
They provide clarity and consistency in error reporting.
They facilitate debugging and troubleshooting by providing clues about the cause of the error.
Additional notes:
Different digital systems may use different error codes.
Error codes can be hierarchical, with multiple codes representing nested or cascading errors.
They can be used to represent both runtime and compile-time errors
